Here is a description of how to replace the front differential bushing with an Energy Suspension 3.2125R 1-3/4" OD Rear Frame Shackle for Chevy Truck. Cost is about $20 (amazon). This is very easy and the fit is great. The only drawback it removing the exhaust if you live in the rust-belt

This was described here without pics http://www.cadillacforums.com/forums/2004-2007-cadillac-cts-v-general/282041-differential-bushing-16-diy-option.html

... so here is a version with pics!!

Take off the exhaust

Remove two rear differential bushing bolts. The bolts do not come all the way out and they do NOT need to.

Remove the front bolt and nut (be careful, you need to support the differential with a jack stand) The differential will drop down enough to service the front bushing

This is what came out of the front bushing (the outer cage stays in place - no need to try and press it out)

Next you need to cut the new bushing down so it is 2.5" overall in length. I took 1/2" off one of the halves to get the correct length.

You also need to cut the center insert down as well.

I just did this . And it was easy. And the results are amazing . Reduced wheelhop. Way stiffer. When you order the bushings it comes with two. So I have a spare. I found out the best way to get the old bushing out was a slide hammer.

seems too me that 50$ for a revshift or creative steel bushing would be worth the hassle of saving 30$. May be just me.

I know this is old, BUT... to anyone who has done this, are you leaving in the metal sleeve before installing the new bushing?

Actually the fact that you don't need to remove the sleeve means you can do it without renting special tools.

I'm wondering about the added diff whine with this bushing.

And having the sleeve still in there means there's less bushing material. It's probably only a marginal difference, but it'll be a bit more firm than the bushings that remove the sleeve.

AFAIK, Energy Suspension uses poly with a durometer that's in the same ballpark as the other bushings that are out there, so it should have the same impact on NVH.

Found this thread as I think I may be due for a replacement in the near future. Like the idea of not having to struggle with removing the sleeve from the old bushing.

Wondering how the long-term results are for this DIY bushing. Also, wondering if this bushing adds differential noise into the interior like some of the others?

Any time you replace a squishy rubber bushing with a firmer poly bushing, you're going to introduce more NVH. How much more noise, and whether it's objectionable or not, will vary from car to car and from person to person. And if your stock bushing is totally shot (as many folks have seen), you might gain a bit of gear noise being transmitted into the cabin, but lose some driveline lash/clunk noises, so the overall effect can be a positive.

Old thread revival!! Yay! I'd forgotten about wanting to do this, but now it's back on my list :) Be interested to hear any reports back on how it holds up too. I wonder if this would be at all possible with the exhaust system still in place...?

EDIT: Also, I see they have a "black" version that is the same durometer, etc, except it's Graphite Impregnated in order to help self-lubricate (wait a second... can we 'graphite impregnate'... nevermind). Would there be any advantage or disadvantage to this for the application that we're using it in (front diff bushing)?


From their site: How are these two colors different?

The only difference between the red and black parts is that most Black Energy Suspension parts are Graphite Impregnated. This serves to help self lubricate the bushings. The Red parts do not have this characteristic. Aside from the actual color and the lack of being Graphite Impregnated - the red parts are essentially the same as the black.

All done.It really wasn't too bad.My exhaust is stainless so came apart easy.Yes you have to drop the exhaust.. I have a machine shop so I turned the bushings to length but you could hacksaw them.Probably had about a hour and half in doing it.
I never drove the car before so I can't compare the bushings.The bushing in it was replaced at one time.It wasn't shot but when I layed under it and lifted on the nose of the rearend it moved up and down.I installed the new one and it doesn't move now.I imagine it will be fine. Jim

Pic or it didn't happen. Lol.
