This is the Super Duty version of our sturdy front differential bushing set. Permanently lubricated, this is designed for extreme driving environments like desert racing, drag racing, rock crawling, and extreme, enthusiastic driving conditions. It will also have much longer service life under normal driving conditions. It does, however, transmit a bit more, yet tolerable levels of NVH to the driver due to its hybrid design with the special polyurethane compound and permanent lubrication used. The transverse insert mount comes with permanent lubrication as well as a zerk fitting that will need to be drilled for after being mounted into its assembly. It is designed to be internally greased in order to flush out its internals from dirt, saltwater or other abrasive contaminants found in harsh environments. The components of this set are designed to work in harmony together, and are offered as a full set and not as their own individual components. http://www.fourwheeler.com/how-to/transmission-drivetrain/1406-2005-jeep-grand-cherokee-front-differential-mount-fix/ https://m.facebook.com/story.php?story_fbid=10207302350237272&id=1840627814
05-10 Jeep WK/XK Super Duty Front Diff Bushing Set
When the stock rubber bushings get old, the rubber degrades, becomes brittle and starts to crack, allowing the front differential to move as it tries to transfer motion to the front tires and hit the chassis excessively. This causes the front half axles and propeller shaft to be at extreme angles at times while trying to transfer power to the wheels, causing excessive wear and premature failure of these components. This also causes a disturbing clunck sounding jolt when shifting from P or R to D or vice versa as the differential rotates and slams against the chassis.
This bushing design when used as a complete set, will reduce most excessive movements of the differential and minimize the problems that come with it. These mounts will reduce differential movement for excellent power transfer from the drivetrain to the ground, but since they are the super duty version of our highly successful sturdy bushing design, they will contribute a bit more, yet very tolerable levels of NVH to the driver inside the cabin due to their hybrid, permanent lubrication design and properties of the special polyurethane compound used.
Made of a hybrid of proprietary materials, high quality polyurethane compounds and solid steel hardware, these bushings will not only firm up the front axle assembly and eliminate that mushy feel associated with the factory stock rubber bushings, but they will also have a long service life compared to their rubber OEM counterparts yet will need minimal maintenance requirements.
These Bushings present an excellent value by not having to be replaced as often as OEM ones, saving on future labor costs and vehicle down time.
Each bushing comes pre lubricated, preassembled and ready to install into your Jeep. Once installed, the pinion and passenger mounts will not require any servicing. Under normal driving conditions, no servicing is required on the front transverse mount insert. In Severe Duty (SD) driving conditions, occassional greasing is required on the front transverse mount insert once mounted, which is easily accessible, in order flush out its internals from contaminants found in extremely harsh environments.
