Rear Differential Bushing - Front Side - 2003-2007 Cadillac CTS / CTS-V

The rear differential (front) stock bushing goes bad on every 2003-2007 Cadillac CTS, CTS-V, STS (and maybe other Cadillac models and years). When the bushing goes bad the car makes a terrible clunking noise, whenever the centrifugal force on the drive train shifts from power to deceleration. The bad bushing causes the rear differential to jump up and down inside a metal casing that used to house a rubber bushing. And it sounds like the transmission or drives shaft is about to fall out. It is a horrible design flaw from GM engineers. The new factory bushing costs only $20, but it is very difficult to replace. The old rubber center piece just falls out once you disconnect the mount and drive shaft and tilt the differential 45 degrees down. But, you have to cut and hammer out the old sleeve of the mount, which is pressed into differential and that can be rather challenging. I was able to get the old one out by cutting a straight line across the metal sleeve, but I discovered that that was only half of the challenge. You still have to install the new bushing, which is a one piece bushing with a metal sleeve that has to be pressed in (ie: it has the same design flaw one you're replacing). And, it is a one piece bushing so without a press or proper tools, forget it. You may destroy the new bushing, and maybe even break the rear differential aluminum housing. Enter REVSHIFT. Thier 2 piece poly type material (with no metal housing) installs easily. Start by installing one half of the bushing on one side of the differential housing, and the other half on the opposite side. Apply the supplied silicon lubricant to both sides of the bushing, then use the same carrier bolt and nut you took off, with large flat washers against both outer halves of the bushing and slowly tighten the bolt/nut. Goes together smoothly with minimal pressure. No fighting to try to hammer and force in the metal sleeve from the old (bad) design. Car drives like a dream again. The way a Cadillac should. No more noise. Way to go Revshift! You have re-engineered GM's poor design. With excellent engineering and quality. I highly recommend this product.

I initially got the wrong one but that was quickly fixed. I just installed it on my diff which is sitting on my workbench. It'll be April before I get to actually drive it but I have no doubt that it will be far better than the stock bushing on my Autocross only Stalker AXR. By the way not many places are selling bushings for this nearly 20 year old diff.

2005 CTs 3.6 that I thought had transmission issues, I was getting inconsistent power at the wheels, clunking. Found a video with the revshift bushing replacement so I jacked my car up to look at my differential bushing, it was completely shot. I purchased the 95a green and just wow. Installation was easy with the 2 piece. It was a snug fit but took me 10 minutes to get it in. (Took 3 hours total dropping the diff). The car acceleration and handling is day/night. I wish revshift made a carrier bearing solution but will be buying other products in the future.

No problem with the install - car drives like new again

I do work on my car, because I am united state Air Force Veteran, I was glad to received the part I asked for, and it fitted my rear differential perfectly.
