GAV01-001 – Rubber Flex Disc – Vw Application – Bolt Circle Dia 120MM – Disc Width 23MM

The GAV01-001 rubber flex disc is the rubber driveshaft coupling used on VW European and import vehicles in place of a u-joint. It flexes to absorb angular movement and vibration between the transmission output flange and the driveshaft — without the velocity variation that a standard u-joint produces at high operating angles. A cracked or hardened GAV01-001 rubber flex disc causes driveline clunk and vibration that looks like a u-joint problem but requires a completely different fix.

Gav01-001 Rubber Flex Disc — VW Bolt Pattern & Dimensions

The GAV01-001 rubber flex disc specs: 120MM bolt circle | 6 holes | 10MM dia | 23MM wide. Includes steel shield, 3 holes threaded, Transporter T4. Bolt circle diameter is the critical measurement — it has to match both the transmission output flange and the driveshaft input flange simultaneously. Disc width determines the angular flex range. Under-rated rubber fatigues fast; over-rated rubber transmits vibration instead of absorbing it.

Flex disc replacement is straightforward: six bolts out, new GAV01-001 rubber flex disc in, torque to spec. The one mistake to avoid is reusing rubber that feels firm but shows fine surface cracking — hardened rubber can't flex properly and the vibration it was supposed to absorb gets passed directly to the chassis.
