Product Details
Description
The Problem:
The stock center support bearing carrier holds the driveshaft in place with rubber so thin about 20 lbs of force moves it from the center to the end of its travel. While that’s great for ensuring no NVH makes it to the cabin, the stock bushing is highly prone to failure, especially in harsher climates and on higher-powered cars. Even on the best-kept cars, the stock rubber bushing sags, dry rots, and cracks by the time it’s 10-15 years old. When the bushing lets go, it leads to excessive vibrations and clunking, damaging the transmission and rear diff. To make matters worse, the stock carrier is molded onto the center support bearing, leading to costly driveshaft replacement.
The Solution:
This upgraded unit keeps the driveshaft firmly in place, and its polyurethane construction ensures it will never wear out. The thick bushings ensure the driveshaft cannot move from the center, maintaining driveshaft alignment at all times.
The Bushings:
Two options are available for the bushings, which are many times better than the stock bushings. We’ve paid close attention to the NVH levels associated with this upgrade. After extensive design iterations, we’ve developed custom isolator bushings that separate the carrier from the vehicle's body 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? Try them both; they’re interchangeable!
Product Features
- Prevents the driveshaft from moving excessively.
- Polyurethane construction ensures it will never wear out.
- Maintains driveshaft alignment at all times.
installation
Installation doesn’t require the 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. The exact steps to access the carrier will vary slightly by model, but the removal and installation of the new carrier is the same. The basic steps are:
-
Remove any braces or splash shields preventing exhaust and heat shield removal
-
Remove or lower exhaust in the area of the center support bearing
-
Remove heat shielding covering the center support bearing
-
Cut off the OEM carrier and remove the center rubber rib with a razorblade, leaving the base layer of rubber intact
-
Clamp new carrier around OEM bearing
