Replacing front-wheel-drive
auto oil seals If there is a leak from the auto oil seals at the inner ends of front-wheel drive shaft, the shafts must be removed and the seals renewed – a task best left to a garage.
Removing the pinion oil seal (rear-wheel drive)Raise the rear of the car on axle stands, chocking the front wheels; also apply the handbrake.
Replacing transmission
auto oil seals Undo the nuts holding the propeller-shaft flange to the pinion flange.Mark the position of the pinion flange and its securing nut relative to the pinion-shaft end, using a centre punch. This is important for accurate reassembling later.
Unscrew the nut, counting the turns needed so that you can refit it exactly as it was in order to keep the pinion and crown wheel meshing properly inside the differential.Put a drip tray under the differential nose to catch the oil. There will not be very much, as the level of the oil in the differential will only fall to the level of the nose.
auto oil seals Tap the flange off its splined shaft, using a soft-faced hammer. If it is stubborn, use a pulling tool.Take care when using a hammer on the flange. Any distortion will result in misalignment of the propeller shaft, leading to early failure of the new seal.
Prise out the old seal with a screwdriver, taking care not to damage the seating.Replacing front-wheel-drive auto oil seals.
