: How many V-owners have NOT had problems with their rear differential?

I have seen the various threads talking about how the rear differential on the V is a POS and several post by people who have gone though 3, 4, 5, and even 6 differentials! From the previous posts, it would seem that every rear differential is simply waiting to self destruct. However, there has not been a recall so I doubt that every rear differential has blown apart. I was wondering how many of you have not had problems with the rear differential in your car? I have over 42k miles on my '04-V with even a few track days thrown in for fun and I have never had any problem with the rear differential. Am I the only one or are there other V owners out there without problems? Am I just one of the lucky few or is it only a matter of time?

I had the first one replaced on my '04 because it was whining and was still under warranty, however, it never broke on me. With the new one installed, I started hearing whine again after about 5,000 miles of my typical spirited driving. Since then I upgraded to a modded 408 that puts about 450 to the ground (conservatively). Somehow, some way, that thing has not exploded on me.

I think it is important to note that I almost never tromp on it in first gear...there's no point, it would just smoke the tires off. It spins pretty bad in second gear but I never rev up and launch like a drag racer. This isn't a drag car so I don't treat it like one.

Hmmm... I wonder if she'll hold up to the new 455?

04, 51K miles, still on my original diff. No smoky burnouts in 1st. I learned to stay away from that from this forum. From the polls Reed has done in the past, I originally thought there were a lot of rears breaking but that's not the case. (The rear diff still is a POS).

Pretty sure I'm on the first diff. Only had the car a few months. Its an 05 with 23K, and I do beat on it when I want to have fun.
I think most of the diffs were changed because of the whine.
Some of the members were talking about the cradle getting tweaked. Not enought to really notice, but enough to give you problems in the long run. Maybe that's why some guys replace them a few times.
It doesn't hurt to change the diff fluid from time to time.

"Be nice to your rear and it will be nice to you."
I never had any issues with mine until I took it to 500RWHP, at about 20K miles.
Then again, many with no mods have had issues (whining, not sure on detonations or failures), but no one can verify their driving style.
The rear has issues, but many seem to work through it.

Thanks to all of you that responded. I feel reassured about the rear differential. The majority of the problems appears to be caused by the type of driving. Clearly, from others posts, the rear differential was not made to take the force of a drag strip launch. What is reassuring is that the rear differential appear to do just fine with the stress of (repeated) track HPDE's.

Happy and Healthy New Year to all of you.

Should be interesting reading your impressions on this rear-end... in a new thread.
Pics of the install would helpful. (Becoming a supporting member would fix your ability to post photos and PM)

FWIW... There is an alternate opinion as to the work done at F-Body Central. See these threads:

Been beating the hell out of my 06 rear for over one year now at the dragstrip. No issues, no whine. I change the diff fluid every oil change, and I also have the BMR antiwheel hop setup. Only noise I get is the extra roadnoise from the BMR setup.

But one thing, I also have an extra 07 rear diff in the garage as a spare that I bought at the local salvage yard for 600 bucks with 4300 miles on it. I still got warranty though.

02-23-08, 06:40 PM
I have an 07 and after 4 months I started noticing a near the rear differential. I took it in and here is what ha happened:

1) brought it in and was told they couldnt see a leak.
2) 35 minutes after I picked it up it started to leak.
3) Brought it back in and had the vent kit installed and pinion seal replaced under recall.
4) picked it up and brought it home. Leak was 3 times as bad.
5) brought it back and was told by mechanic that he was going to replace differential and that when he called GM he was told that they weren't exactly sure what is causing it.
6) drove it 7 miles home and parked it because the weather was bad... Still leaking fluid.

Does anybody have any ideas on how to correct this or just some advice? After owning BMW's for 10 years I drove a friends V and was impressed by the power/ price point. I am beginning to regret that I didn't pony up and buy the M5......

02-23-08, 07:07 PM
this is the second dealer I've been to... it seems to me they did everything they could and it still isn't right. After reading all of the posts on this forum I find it hard that anyone could disagree that the diff can't handle the power. The cars has 3200 miles on it and was broken in properly... it has a brand new diff in it and still leaks.. open to ideas.. I think saying that the tech' dealer isnt good is BS.

CTSV_Rob
02-23-08, 07:16 PM
I think saying that they can't find the leak and that they have good technicians could be BS as well.

We all know the Diff's weren't designed to handle the HP properly and the car has wheel hop problems but mine is no longer stock and the rear is still quiet. I brought my car in for a leak and it turned out to be that vent mod. once they installed that I have had no problems with mine.

Now I change out the fluid about once every 7,500 and I have changed to the AMSOIL fluid. I don't want to get into an argument about which fluid is better because I really don't know. The only thing I can tell you is when I changed the fluid the first time at about 6K I found a lot of what looked like clutch material in the fluid. This abrasive material cannot be good on the internals so it is a good idea to change the fluid more often then the factory recommends.

besides, unless the case has split open the leaks should have nothing to do with the power that the Diff can handle. It would mean there is a seal problem or a leak in the drain plug for example. This is all repairable even on our Diff's so I don't understand why you don't think it could be a technician problem.

I can guarantee that Lindsay would fix this right the first time and it would be better then from the factory. Bummer is I am on the other side of the US so I hope I don't need them and I don't know where your located but I assume it's no where close either.

My post was not meant to insult you or your car and I apologize if I offended you. - Good luck with your leak.

ctsv07
02-23-08, 07:20 PM
no offense taken... the first dealer didnt see the leak.. the second dealer came highly recommended as well as the technician. He has changed diffs on another ctsv and I have no reason to believe he isnt competent.

CTSV_Rob
02-23-08, 07:30 PM
Can you tell where the leak is coming from? I assume your in snow country so getting underneath the car is probably really miserable.

I sure hope they can fix this for you becuase if you turn to an M5 I'm sure you would enjoy the car but something about the V is just intoxicating. With that said I really like the car much more with the mods I currently have installed. The headers, shifter, flywheel, sway bars, cat back, tune,.... really transformed the feel of the car, not refined but much more beast like yet the cops still don't give me a second glance.

02-23-08, 08:29 PM
CTSV_ROB: There was a pic of the leak that another forum member downloaded that looks just like mine. It started off on the left side of diff and after they added the vent kit the leak went to the right. The tech told me the kit is on the right so it makes sense to me that the leak is probably from the vent. I will take a pic tomorrow and post. I love driving the car and agree that it is intoxicating! I hope they can finally figure it because that new 09 looks mean. My lease will be up right around the time they should have the bugs out of it!

Wicked_V: I drive mine aggressive too but not like an idiot.I only had 3400 on my old diff and about 7 on the new one. i'm gonna keep my fingers crossed and hope that they fix it this time. I broke it in exactly ow they told me. I treat all of my cars/ harleys the same.. break em in slow, ride em hard, and maintain the heck out of them!

65,XXX miles. Handful of 1/4 mile passes. Plenty of hard launches (always from idle or less than 2k) on the street and 2nd gear rips and not so much as a peep or a drop of fluid leaked. I dont even wheel hop as much as I did 30k miles ago and Im running all season BFGs at 37psi.

ctsv154
08-31-08, 12:16 PM
I think a lot of the problems were wheel hop but also the seals leaking. There is hardly any fluid in our diff anyway. Add a leaky pinion seal and a leaky driver side axle seal and it doesn't take much to loose that 1.5 or so qts of oil.I had a new diff less than a year ago because of the whine. Both the pinion seal and the driverside axle seal are leaking. I have replaced the pinion seal but haven't had a chance to get the axle seal in yet. But its higher than the pinion so I'm not as worried about it as the pinion.

Just making sure the diff has the proper amount of oil in will help a lot! I drive my car very very hard. I dont try to get it to hop but sometime is hops pretty good. I have rolled backwards just a few miles an hour and than droped the clutch in first and as soon as they start to spin, grab second and spin all the way through second until they hook. I have done about anything you can imagine to that car and still no whine or anything. I think the main key is the proper amount of oil and good clean oil.

08-31-08, 11:20 PM
16,000 miles and my original diff was whining a little. That was until I got my B&B x-pipe and I don't hear the diff now. :bouncy: I launch hard and try not to make it hop.

I do have some weapage coming out of the diff sometwhere. It is gradually coating the entire side but isn't enough to drip. I still have a year of warranty left, so I will wait until it breaks.

The Harley dealer has 3 leak levels from worst to least. Leakage, seapage, weapage.

70,000+ miles on my 05 V. I only had it since May, but there is no record of a diff replacement. Had the rear pinion seal replaced on recall when I bought it. Id assume they replace the fluid at that time. I had it hop a few times pretty hard, but I won't induce hard hop anymore because it makes me cry. I sure would love a REAL hop fix! Makes me miss my Camaro. Almost as fast, but way more fun to abuse. Oh well, I love my kids.

' 04 with 46k and original diff. No leaks. The diff, and the rest of the drive train has an incredible amount of slack/backlash...the famous clunk is audible over the Corsas by nearby pedestrians...especially when my 16 year old with a brand new permit is out practicing. Between the trans, driveshaft support, and diff, I've got to do something.
I replaced the front diff mount bushing with a Delrin one...holds the diff firm, but I don't recommend it due to the transfer of pinion whine into the cabin....no noticeable whine with the stock bushing...until it self destructed.
No dragstrip or autocross here. Just a DD I drive hard year round.

Is that the original KARS III or the new one that csp3000 is selling?

I'm still on the original differential. '05V with ~36,000 miles (most with a maggie)

'04, 36K, original diff., no problem to date, no hole shots, only do WOT when already rolling. Wheel hop apparent during 1st-2nd speed shift at high rpm.

No issues with my 05; did change the diff oil with Red line 75/90 W upon recommendtion of several members on this forum.

' 04 with 46k and original diff. I replaced the front diff mount bushing with a Delrin one...holds the diff firm, but I don't recommend it due to the transfer of pinion whine into the cabin....no noticeable whine with the stock bushing...until it self destructed.
No dragstrip or autocross here. Just a DD I drive hard year round.

Still have wheel hop city even after installing the Kars III.



Where did you get a delrin front diff mount bushing? Would a urathane bushing be better? That is a shame about wheelhop with the KARS III. :tisk:

I don't have any problems with my '06 diff, and it doesn't make a peep after changing to RedLine 75w90.....the 1st diff was a different story though.

27K miles on my 06 V, and 0 problems.

Not sure if this is old news....

Wow, this thread has some legs!

Well, 9 months and 10k more miles, a couple of track days, and still no rear differential problems.

Hope to see many of you at V-day II.

Not on this subject but page 1 of 3 on the engineering analysis closing report states the cts-v population as model year 2004 2432 units model year2005 4048 units and model year 2006 only 1162 units for us market volume these #'s differ slightly under faq for 2004 then 13% over for 2005 and way under faq estimate for 2006. which do you think is most accurate? if the report is 2006's should be pretty rare. ;)

I have about 18K on mine now and a couple of track events and no whine. Time to do another fluid change though...

I use AMSOil and the GM friction modifier with no issues so far *knocks on wood*

Made it. Seems to me anything with a better durometer, such as urethane, would dampen the vibes. I believe a urethane version is commercially available. Just happen to have a chunk of Delrin handy when the need arose.
