Driveshaft seal question
Hello, have a RHD V50 D5 manual (M66) gearbox and ordered a driveshaft seal (for inside transmission) as it was leaking and thought to order the seal from the other side too to change both at the same time. The two seals given to me by the dealership are diffrent with one seal for the passenger side being much larger than the drivers side which I questioned the dealership but they assured me it was correct. Lo and behold after removing the drivers side drive shaft the seal before me was identical to the one on the passengers side being much larger than the seal which is given to me.
Is there two seals on the drivers side or did the dealership give me the wrong seal?
Image shown is the drivers side seal and the other image is the part given to my by the dealership for the drivers side.
