Quick question, how much that block weigh? Looks like I can replace 4 45lb plates on the bench press bar with that block. lol

Wow, won't be much of that left when your done. How long do you think it will take to hog out all of that material?

That will be one solid rear end when your done.

You know, since the program would be done already have you thought about an aluminum upgrade? Doing it out of a solid chunk of aluminum should be stronger then the cast case plus you could make it a little thicker and more ribbing.

Strength, weight savings,...

Just a thought and maybe a bad one. The casting these days is probably much better then the casting of the old days so there probably won't be much gain but I had to ask anyways.

Can't wait to see the final cut.

lol i'm pretty sure that weighs a couple hundred pounds easy. i'd be surprised if you could squat that, let alone bench it :)

Yeah, but if it works we can get rid of our cast aluminum units that will break but not bend and get a steel unit that will bend but not break.

I've looked at doing this for the last 3 years,I've yet to find a way.Cutting is really no problem,just time consuming.The material is the problem,shit moves around like crazy,especially when you need heat treating.Theres a reason they use cast metal guys,it stays straight,it will not bend, it will break from shock.Maybe if these guys are carefull and hog all the excess meat off this forging,carefully heat treat the case,and then finish all the I.D. bearing surfaces,maybe,just maybe they get a usable piece.No friggen way they could ever make a buck selling them here.That square chunk of recycled shit cost more to make and ship than what I want to pay for the case.But hats off to these guys for having the balls to do this,I wish them all the luck in the world.I'm not flaming here at all,just telling it as I see it.Randy

Mild steel doesn't have a high enough carbon content to respond to heat treatment so what you see is what you get. I'd have chosen 4130 chrome moly.

I think the important thing here is that even if the mild steel experiment fails, valuable lessons can be learned and applied to a different material.

For the record: I hope you're successful. If it fails the first time, you've got most of the work done and it just comes down to choosing materials.

CTSV_Rob
12-14-07, 12:21 PM
My post was not meant to be negative but just a question about possibly using different materials.

I work in a machine shop as well and one thing I have noticed is when you mill out that much material it will put stress into the part. For large pieces of SST (even Prodec) we usually rough cut the material then send it out to have it annealed to remove any stresses that the initial maching may have put into the part. Once annealed then you can do the finish cut.

Not sure how much the metal will move when you heat treat as I do not have alot of experience with this process.

As with anything that is machined it is a learning process and when you figure it out you will have the "recipe" for making that part successfully. I'm sure there will be a couple of surprises and I sure hope you push through them. Once you have done it, sell the final product but don't give away the recipe, you should profit from it.


Good luck to you and I cannot wait to see the final product.

Build it, you won't regret it. When I started my twin turbo project, there were a bunch of guys trying to give their "expert opinions" on what I was doing wrong. Most of them probably drive bone stock cars and wouldn't know where to start if they wanted to do their own mods. You'll have bumps in the road with this projects, but with some perseverence this will be an awsome project. Besides, getting there is half the fun.

I am curious what type of steel it's made out of. Somehow we leaped to milt steel. In this post CG, indicates its' 4140. Perhaps CG or Nutz can chime in the metal type.

Machining chunks of steel that size is common place in the injection molding industry. I have a small molding shop and I have one mold machined from a solid piece that is 20" x 25 x 12 thick. People make molds from everything from aluminum to tool steel. You just have to know what you are doing. These days some mills run 80,000 rpm or higher and take very small cuts so they do not heat the steel. Most molds are far more precise than what would be required for this rear end.
Machining this prototype will be time consuming/expensive. If everything works out, casting the part and machining to specs would be the way to go to keep prices down.

4130 can be normalized by heating to a cherry red heat and letting cool in still air, a simple heat treatment. 4140 is more prone to distort and crack with heat treatment. I was suggesting something better than mild steel that the average bear could handle easily. I was a journeyman machinst when I was 17 years old 50 years ago and I 've been in and out of the field ever since, grasshopper.

I think this is a great project. It's well thought out and ought to produce interesting results. Has anybody thought about approaching the problem from another angle and weld some reinforcing onto the original aluminum housing. Fifty years ago we used to weld a lug on the inside of Ford differential housings so we could screw in an adjustable bolt with a big lump of brass on it that was set for a few thousanths clearance on the back side of the ring gear. When the ring and pinion loaded up and started to separate the ring gear would hit the bolt and it would support it.

It seems to me that if there is a basic weakness in the aluminum housing that reinforcing can be TIG welded onto the outside to beef it up. Careful preheat would reduce warpage. Bearing bores could be welded up and remachined for the correct alignment. Since the housing is cast it has to be a weldable alloy. The very best facility I know of that does this kind of work is Nickson's Machine Shop in Santa Maria, California. These guys have been doing unbelievable work for over 60 years. This place oozes extreme craftsmanship. It would be well worth somebodies time to take a cracked housing to these guys and see if they think they can improve /reinforce it. It would be well worth anybodies time to just take a shop tour and see how it's done by the old school masters.

Another absolutely first class operation is Precision Engineering in Seattle, Washington. These guys also perform machining miracles.

My brother-in-law works for John Deere in Waterloo, Iowa. He makes obsolete parts from billet stock using CNC tooling that were originally made from castings that are no longer available. They bring him a print of a part that hasn't been made for 30 years and he turns it out. He also machines prototypes and makes "impossible parts". Every manufacturer from time to time designs an impossible part that it seems like it just cannot be made by humans and he figures out how to untie these Gordian knots. In my estimation he has the best machine shop job in the world and he makes really good money.

I think this is a great project. It's well thought out and ought to produce interesting results. Has anybody thought about approaching the problem from another angle and weld some reinforcing onto the original aluminum housing. Fifty years ago we used to weld a lug on the inside of Ford differential housings so we could screw in an adjustable bolt with a big lump of brass on it that was set for a few thousanths clearance on the back side of the ring gear. When the ring and pinion loaded up and started to separate the ring gear would hit the bolt and it would support it.

It seems to me that if there is a basic weakness in the aluminum housing that reinforcing can be TIG welded onto the outside to beef it up. Careful preheat would reduce warpage. Bearing bores could be welded up and remachined for the correct alignment. Since the housing is cast it has to be a weldable alloy. The very best facility I know of that does this kind of work is Nickson's Machine Shop in Santa Maria, California. These guys have been doing unbelievable work for over 60 years. This place oozes extreme craftsmanship. It would be well worth somebodies time to take a cracked housing to these guys and see if they think they can improve /reinforce it. It would be well worth anybodies time to just take a shop tour and see how it's done by the old school masters.

Another absolutely first class operation is Precision Engineering in Seattle, Washington. These guys also perform machining miracles.

My brother-in-law works for John Deere in Waterloo, Iowa. He makes obsolete parts from billet stock using CNC tooling that were originally made from castings that are no longer available. They bring him a print of a part that hasn't been made for 30 years and he turns it out. He also machines prototypes and makes "impossible parts". Every manufacturer from time to time designs an impossible part that it seems like it just cannot be made by humans and he figures out how to untie these Gordian knots. In my estimation he has the best machine shop job in the world and he makes really good money.

Maybe I'll have to break mine and take it over there. I live in Santa Maria.

4130 can be normalized by heating to a cherry red heat and letting cool in still air, a simple heat treatment. 4140 is more prone to distort and crack with heat treatment. I was suggesting something better than mild steel that the average bear could handle easily. I was a journeyman machinst when I was 17 years old 50 years ago and I 've been in and out of the field ever since, grasshopper.

You need to talk to an oldtimer at Caterpillar tractor company, now Caterpillar, inc. It was a CATERPILLAR No.12 Motor Grader. That's what it said on the side of it and what was written on the parts book. This CAT thing is what the kiddies that run the place call it now. That naming convention has only been around for twenty years or so. For that matter, when I was a kid there were still a lot of machines around that said Holt on them. Come around and tell me all about it when YOU can build a level road with an RD8 with a cable blade. In fact, I'm betting you couldn't get it started.

Still looking for a bushing encapsulated with upgraded urethane... Does anyone have one to offer?? If not, please send me someone highly recommended so I can purchase one. BMR??

Also if anyone has some information on diff lubricant: Normal operating temperature, and peak temperature. This will help in effectively testing the steel unit in my car.

Next will be a request for a suggested oil cooler to use with it, we have of course incorporated tapped locations for fittings.

Heres the fluid needs:
Three quarts of #12378261 GM Synthetic Axle Lube SAE 75W-90
One 4 oz. bottle of #1052358 Limited Slip Axle Lubricant Additive (thanks to Reed @ Cadillacfaq.com for the info)

The normal op temp that I recall was in the 195-210 range...that stuff was always hot coming out during post 'new rear' breakin.

Regarding liposuction. It reminds me of my favorite sayings: "You can't polish a turd". Think of the V as much like the wife, it runs really good and it would be nice to drive it every day, but the rear end has to be quality.:alchi:
As for how much it weighs. It is appearing to be lighter than we predicted. Not done cutting metal off yet and drilling, but at least 400 lbs. have been removed of of the near 530 lb. block! Heat treating is definatelty being considered, but probably not on the first one though.

This project is primarily being done to address CASE FAILURE and it's mounting locations. Attempts at hybrid differentials are already out there, and some are still running in cars successfully. This is a different approach.

I guess that brings up another question, do most people break their cases when they're talking about 'blowing up' their rearends or is it the internals that go?

The catistrophic failures have mostly (?all?) been case fractures. I don't recall seeing any pics of busted teeth on the ring or pinion. The 'howl/whine' domes from the defection of the weak case, the fact that the whole thing moves around so much due to the bushings attaching it to the cradle, and then fially by the suspension geometry and poor bushings connecting the cradle to the frame of the car (whihc induces wheelhop, which puts the @ss smack on the DIFF's).

Both Quaife and Torsen make replacement differential inards, which should be stronger than stock. I'm not sure this would be needed in most peoples application, as I think the bilet case would work pretty weel with the stock bits inside.

I guess the ultimate setup would be the billet case, with Quaife/Torsen internals, replacement differential bushings (come on UUC!!!), replacing as many of the softer bushings in the rest of the suspension (GM Racing Upper sway bars with hardened bushings, BMR toe and trailing arms), doing something about the cradle bushings (they have to be burned out so no one has really done a swap of those that I'm aware of), or installing some form of cradle brace (a la BMR AWHK, or KARS Cradle kit). You'd then need to beef up the half shafts (to at least the bigger '06+ ones). I would HOPE that setup would be enough to shift what breaks in the drive line somewhere else.

Watching this and waiting (and hoping it works).

My car is bone stock with resonator removed and Flowmaster Super 44 mufflers. I feel that it's necessary to test this FIRST on a stock car, and should something fail than it surely is a dud. Performance parts can take place rather quickly if I wish to turn up the heat on stress. I don't want to get into details here but I have many resources available to me here in Cleveland to make the car fast and reliable (I'm quite experienced at doing that).
Price? Well it would be foolish at this time to discuss price until this process has run it's course and I'm done spending on this first one. Rest assured, I am spending WHATEVER it takes to build this one at any cost, and will review all my options and opportunities thereafter. Believe me, if this first one works I am very well aware of the need, and fully capable to provide. I am a car guy like alot of you.
As for the complaining, I think we have been on track quite well here for the last couple weeks, and let's keep it that way! Everybody has had some nice things to say lately, and that's what keeps me around. :rant2:

I will try to say this "tactfully".......there are a lot of "experts" in this thread (I guess, including me) with advice. I personally feel these guys are on the right track. None of us like Getrag. But, these guys have been around for a long, long time. I think they "usually" make a quality part. I'm guessing here, 'cause I don't know.....GM may have asked for the diff case to be aluminium for weight savings....just a guess. I feel the "innards" are top quality parts. Why would I say that? I have very loud whining and the "grinding" while turning slow.....VERY LOUD. My dealership is going to warranty the diff next week....(I'm out of town right now). I drained the fluid a couple of days ago to "see" what's up. It came out "clear".....by that I mean no contamination or anything. It had about 2000 miles of "whining and grinding" on it. So, I'm feeling the weak case has "shifted" somehow, causing this "noise".....I think when these guys finish a case that holds its "shape" the diff will start holding up the way it was designed. Ok I'm done.

Did you call me a Psychopants? LOL. But seriously folks... Tony's point is an exvellent one. A little prudent skepticism is probably a good thing, particulalrly considering the likely cost of such a project. However, having owned a CNC race parts business at one time myself, I think it's important to note that now that the programming is done, these can be turned out by the gobs, which will ultimately lower the cost. Steel will definitely solve the problems with this rearend, particularly if it's 4340 and heat treated.

It's really a dilemma on painting ideas. We are probably going to paint THIS one red to highlight what has been designed. The other choice is definately Dupont clearcoat. I think Custom will agree that hurdles never happened, and everything went exactly as he planned (and I hoped for).

Things went well!!! The only tine consuming part I had was finding the right tool for the tricky deep pockets. I would try 2 or 3 different insert geometries and depth of cuts before got the right combo. I had to make 2 fixtures to keep chatter and part deflection to a minimum. nothing out of the ordinary when your trying to cut a part that rings like a bell. the good part about it is that all the time consuming stuff is all done. programs are proved out, fixtures are done and machining process worked like a charm!!!

I'm not questioning your knowledge of pinion defliction, I'm questioning mine!!!

Most of the failures (that I saw) involved the front pinion area of the case and plate.

All the supposed "fixes" involved bolting some reinforcement to the plate, which led to the case letting go.

Ergo, fix the case and the plate should fail next, depending on clutch dumps vs wheel hopping it so the side plate fails.

I think you should nickel plate or gun blue it. :cool2:

All intention is to have this running in my car in the next week or two. Custom has been battling a family flu bomb, and I have had some root canal issues, not to mention holiday commitments. Also hoping for good test weather here in balmy Cleveland, Ohio. Thanks for looking.

No. Focused strictly on diff housing and front support area. Most other parts are either bolt-on or have already been offered as an upgrade.

Waiting on professional paintwork to be completed:yawn:. Reassembly should be tues or weds. (right about the time the weather starts getting crappy probably). I hope to have it in my car by next weekend. Maybe a little behind though, I expect to be crawling all over the NEW V as of 9:05 A.M. Thursday morning up in Detroit.

Dang NUTZ,

Your are getting serious, aren't you ?

Let me know when you get the rear end home, if you need help with the r/r I might be able to help.

It's done! This is the NEW STEEL DIFF HOUSING.
After paint work and reassembly, I hope to have this in my car in the next week or two.

A work of art!

That IS a work of art.

How do you expect it to be on heat transfer to the outside air compared to the original? If it is not a good, it is pretty easy to set up a cooler and pump.

We have incorporated 2 tapped fitting access holes for a cooler just to be safe, and also to support road racing needs. We also designed some areas to trap air to help.
