Diff pinion seal qestions

mudmut · Nov 1, 2014

I have an 1989 90 and both the front and rear diff pinion seals are leaking, first question, is the bearing spacer shimmed so i can just undo the pinion nut replace the seal and re torque the nut or is it a crush spacer?
Next question is what seals to order, the axles front and rear have disc brakes.
Cheers

pinion bearings use a shim to set preload so you can just retighten nut ,seals are frc8220

Hi don't forget to check your axle breathers too
If blocked they allow pressure build up as the gear oil warms and aghhhhh another seal failure again

Good idea, i suppose the easiest way is to blow them through with an airline.
