04-07 CADILLAC CTS REAR DIFFERENTIAL BUSHING
This urethane bushing replaces the low quality, factory installed bushing in the FRONT of the rear differential. If there is a “clunking” sound coming from the rear of your car as you are on and off of the clutch while driving slowly, the failure of your front differential bushing is the probable cause. The material that the factory used for these bushings is very soft, they left considerable air space in the bushing and this bushing is under tremendous strain during vehicle acceleration, these three points lead to the early demise of the factory bushing.
Our replacement bushings are made using a urethane material that is stronger that the OEM rubber and the bushing is 100% filled (no air space) which minimizes deflection between the inner core and outer shell of the bushing. The use of our bushing will add minimal (if even noticeable) noise transmission to the cabin from the rear differential.
In the photo with two bushings, (click on view larger image) the bushing on the right is a new OEM bushing. We posted this picture for a comparison of the two products, ours and theirs. When you remove your old bushing it will look far from what you see here, it will be painfully obvious that it has gone bad.
