034Motorsport Driveshaft Center Support Bearing for Audi A4 Quattro Cabriolet, A6 Quattro, and S6 (1998–2009)

034Motorsport's driveshaft center support bearing carries the middle of the two-piece driveshaft on the B6 and B7 Audi A4 Quattro Cabriolet and on C5-chassis A6 Quattro and S6 models. Watch the build cutoff before ordering. 034Motorsport states that late B6 A4 cars with a VIN of 8E-4-030693 or newer need its separate late model center support bearing rather than this one. This part also does not fit the allroad or the B6 and B7 S4. Audi does not sell the support on its own through the dealer, so 034Motorsport makes it in-house from precision-stamped steel with an OEM bearing.

034Motorsport parts sold by PMB carry a 24-month warranty.

On a two-piece driveshaft, the center support keeps the shaft steady at its midpoint so it stays in line between the transmission and the rear differential. A worn support on these cars typically shows up as vibration at certain speeds and loud noises from the driveshaft tunnel, and a new support fixes those issues. No core return is required. The part is made in the United States at 034Motorsport's Fremont, California, facility, where the company designs, tests, and builds its parts.

Common Questions

My B6 A4 is a late build. Does this fit?
Not if the VIN is 8E-4-030693 or newer. Those cars take 034Motorsport's late model center support bearing.

Will it fit an allroad?
No. 034Motorsport excludes the allroad and the B6 and B7 S4.

Installation & Tuning Notes

Plan on removing the driveshaft from the car and splitting it. Carefully pry open the crimped boot at the center joint and hold it back to reach the hidden clip inside. Releasing that clip is the tricky step and usually needs two people. With the halves separated, take off the locking c-clip on the bearing and press the old support off. Reassemble in reverse order.

For quattro owners chasing a driveline vibration, PMB sells this support as a direct replacement part.

Fitment & Compatibility

Check the fitment table below for the models and years this bearing fits. Late B6 builds need a different support, so compare your VIN with the cutoff above. Send us your VIN and we will confirm fit before you order.
