Replacing axle-shaft auto oil seals (live rear axle)
The design of the seals varies greatly from car to car. There may be up to three on both sides of the inner race of the bearing, and a ring outside it. Always replace all the auto oil seals when you remove a half shaft as they often leak after being disturbed .
Prise them off carefully with a screwdriver, taking care not to damage their seatings, and clean the seatings.Smear the new seals with multipurpose grease and push them in carefully with a piece of tube of a suitable size.
auto oil seals Use a degreaser or paraffin to clean the area around the differential nose, thoroughly wiping up the mixture of oil and dirt caused by the oil leak. Dry the area with absorbent rags.Clean the inner rim of the flange where it touches the seal, and lubricate it with hypoid gear oil.
Tap in the new seal, using a socket of the appropriate size and a soft-faced hammer. Be sure to fit it the right way round, with the lip facing inwards. A special tool of the right diameter is available for some cars, for pushing in the seal, but it is usually not necessary.Replacing axle-shaft auto oil seals.
Grease the lips of the seal with a multi-purpose grease.
Oil the splines and refit the flange, holding it square to the pinion so as not to damage the seal. Give the nut the same number of turns that it took to remove it, and line up the marks you made earlier. If the nut is self-locking, fit a new nut.
auto oil seals Check with a torque wrench that the setting for the nut corresponds with that given in the workshop manual for the car, to provide the correct load on the pinion. Adjust the setting if necessary. Fit a new split pin on the nut, if required.
Reconnect the prop-shaft flange to the pinion flange. Top up the differential housing with fresh hypoid gear oil to the correct level.Replacing axle-shaft auto oil seals.
