Title: Rear Diff
Post by: Growler on 26 July 2008, 14:17:25

I have a leak coming from the front of the rear diff (i think that's what it's called) where the drive shaft enters the housing, it's not real bad yet mostly just wet rather than having a drip, how can I fix this?

I found the answer myself in the how too... section it's the diff pinion oil seal that is leaking. Should have looked there first  :D

There you are then, it always pays to read the Maintenance Guides :y

Hi,If the leak isn't too bad, then it's not really worth all the hassle of replacement seal, and all the hassle of trying to get the pinion bearing pre load back as it was, with all the dangers of damage if you get it too tight.

This is what I did with my Senator, it was only leaking half litre of oil in 100,000 miles.

If you open both ends of a baked bean tin, then cut lenthways with a pair of tin snips, then fiddle this over the front of the diff, the housing where the pinion seal is, making sure it shrouds over the oil thrower ring, fix it with a Jubilee clip, then the fine oil mist that is leaking won't go all over the exhaust pipes and underfloor of the car.
