Long Life, Soft Polyurethane, Steel, Upgraded and Re-Designed Front Differential Bushings SET (ALL 3 to replace the main cross member and the two outboard bushings) 

Product Description 

When the stock rubber bushings get old they harden, become brittle and start to break down, allowing the front differential to move excessively. This caused the front half axles and propeller shaft to be at extreme angles while trying to transfer power to the wheels, causing excessive wear and premature failure of these components. This sometimes is also the cause of a knock sounding jolt when shifting from P-D, P-R or vice versa. 

We redesigned these bushings to reduce most excessive movements of the differential helping deliver full, smooth power to the front wheels of your Hummer. 

Those are honest-to-goodness, serious, Long-Life bushings and not like typical two halves bushings found elsewhere.

While this mount reduces differential movements for excellent power transfer from the drive train to the ground, they do not contribute excessive NVH (Noise, Vibration and Harshness) to the driver inside the cabin due to the softer properties of the polyurethane compound used. 

Made of high quality polyurethane material with steel sleeve and pin, these polyurethane bushings will not only firm up the front axle assembly and eliminate that mushy feel associated with the factory rubber bushing, but will also have a very long service life compared to their OEM rubber counterparts, reducing future labor costs and vehicle down time. 

Each bushing comes prelubricated, preassembled and ready to mount into the differential. Once installed, no further servicing is required. 

You don't have to replace a whole part and pay dealership prices for it, just because of worn out bushings. Just simply press your worn bushings out and press the new ones in.
