Drive axle seal for all 5 speed manual (02J) transmission in A4 chassis TDIs & 02A 5-speed in A3 Jetta TDI and B4 Passat TDI and the 5-speed manual in the MkV BRM Jetta TDi.
While this fits both sides, the passenger side one has a flange attached to it, so you may want to replace the flange and seal together instead of the seal alone. The driver-side does not use a flange. The flanged-seal is available.
