05-10 JEEP GRAND CHEROKEE FRONT DIFFERENTIAL BUSHINGS
These urethane bushings replace the low quality, factory installed bushings in the front differential. If there is a “clunking” sound coming from the front of your vehicle during acceleration, the bushing above the pinion (pinion bushing) is the probable cause. The material that the factory used for these bushings is very soft, they left considerable air space in the bushings and these bushings are under tremendous strain during vehicle acceleration. These three points lead to the early demise of the factory bushings.
Our replacement bushings are made using a urethane material that is stronger that the OEM rubber and the bushings are 100% filled (no air space) which minimizes deflection between the inner core and outer shell of the bushings. The use of our bushing will add minimal (if even noticeable) noise transmission to the cabin from the front differential.
We offer two different durometers for either a daily driver-street car or a full on race car. With that said, here is a breakdown of what we suggest a customer purchases dependent on the use of the vehicle-
- Daily driver/ stock or minimal modifications- We suggest purchasing the black pinion bushing only. The pinion bushing takes the majority of the abuse and is the only bushing that seems to fail under normal everyday use.
- Occasional racing or off-roading (750hp or less)- We suggest the full kit in black. This will keep the differential in place without transmitting much noise or vibration.
- Race car/ hardcore off-roading(unlimited HP)- We suggest the full kit it red. With our red bushings the differential will be held in place and have a hard time moving. With the full red set you might notice noise and vibration as the urethane is a lot stiffer than the factory bushings.
***You can always purchase whatever bushing you need if your factory bushing has failed.***
