Dodge WD Durango Jeep WK2 Grand Cherokee Driveshaft Center Support Bearing Carrier Upgrade
Fixes the torn rubber on your factory carrier without having to replace the driveshaft or bearing. Installs in an hour.
Holds the driveshaft where it should be. Isolation dampers minimize vibrations.
Fits WD Durango (2011+) and WK2 Grand Cherokee (2011+). All variations including 2WD and 4WD models.
Bushing Options:
- Street (Soft/Quieter)
- Track (Hard/Louder)
- Both Street (Soft/Quieter) & Track (Hard/Louder)
The Problem:
The stock center support bearing carrier is permanently molded to the center bearing with thin rubber that sags and cracks over time and does not adequately support the driveshaft under load. This rubber generally fails long before the bearing itself has reached the end of its life. Since the center bearing is molded to the OEM carrier and difficult to service, it’s often easier to get a new driveshaft than replace the center support bearing.
The first video below was recorded on an Audi, and the 2nd on a BMW, but Chrysler (and everyone else’s) OEM carrier design is similar. The shaft is not well-supported by the soft OEM carrier, so it’s allowed to travel off-center during rapid loading and unloading. The second video shows a comparison of how much an OEM carrier gives under load and the improvement with the JXB carrier.
The Solution:
This upgraded unit keeps the driveshaft firmly in place at all times, and its robust construction ensures it will never wear out. The thick bushings ensure the driveshaft cannot move from center, maintaining driveshaft alignment at all times. The 2-piece design clamps around the bearing, making installation and servicing a breeze.
The Bushings:
Two options are available for the bushings, both of which are many times over better than the stock bushing. We’ve paid close attention to the NVH levels associated with this upgrade. After extensive design iterations, we’ve come up with custom isolator bushings that separate the carrier from the body of the vehicle and mounting hardware. These carriers substantially reduce NVH levels.
The street bushings absorb most of the NVH from the drivetrain. Some light NVH is possible at some speeds in the form of a soft hum. With a modified exhaust or windows down you’ll probably never hear it.
The track bushings are for those who want no-compromise drivetrain performance. These may create a substantial amount of cabin noise. Not sure which is for you? They’re interchangeable so you can try them both.
The Installation:
Installation doesn’t require removal of the driveshaft. The 2-part design clamps around the OEM bearing. The old carrier must be removed, so a cutting tool is required. Below is the installation of this part on an 2014 Durango. The exact steps to access the carrier will vary slightly by model, but the removal and installation of the new carrier are the same. The basic steps are:
-
Remove any braces or splash shields preventing exhaust and heat shield removal
-
Remove or lower exhaust in area of center support bearing
-
Remove heat shielding covering center support bearing
-
Cut off OEM carrier and remove rubber support material with razor-blade, leaving base layer of rubber intact on the bearing
-
Clamp new carrier around OEM bearing
Fitment:
Does not fit the Durango SRT Hellcat with the 1-pc aluminum driveshaft.
