JXB Performance Driveshaft Centre Support Bearing Carrier Upgrade For Audi 4L Q7 With OE Driveshaft 7L8521102H/L - 4L002A0

JXB Performance Driveshaft Centre Support Bearing Carrier Upgrade For Audi 4L Q7 With OE Driveshaft 7L8521102H/L - 4L002A0

The Problem

Thestock center support bearing carrier is designed to reduce NVH to the cabin by loosely holding the center bearing with flimsy rubber spokes. During launches and shifts, the driveshaft is allowed to travel off-center, decreasing throttle response and causing oscillations through the drivetrain. As they age, the carrier rubber sags and dry rots, ruining the driveshaft alignment.

The Solution

This upgraded unit keeps the driveshaft firmly in place at all times, and its solid construction ensures it will never wear out. The thick bushings ensure the driveshaft cannot move from center, maintaining driveshaft alignment at all times. Isolation dampers separate the carrier frame from the body, minimizing NVH transmission.

The Bushings

Two options are available for the bushings, both of which are many times over better than the stock bushings. 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? Try them both, they're interchangeable!

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.

Fitment

Audi Q7 4L models with OE part number 7L8521102H/L driveshafts fitted. These driveshafts have a smaller diameter bearing and are typically found on early TDI Q7 4L models.

Any other 4L Q7 model should use JXB part number - 4L001A0
