Disco2 Rear hub oil leak

rfhdisco · Aug 5, 2017

Hi,
I just wanted to bounce this idea off forum members.
In April I had the nearside rear hub replaced as there was a leak,the new hub cured the leak until now.
I have had a situation years ago were an oil seal had worn a groove in a crankshaft thus causing a leak, does anybody no if something similar could happen to a high mileage half shaft which would mean the new hub oil seal would not hold oil back for long before it started to leak.

Regards Ron

Doubt it. Was probably just installed poorly. Was the shaft seal changed at the same time as the hub? If not, you've probably had a worn seal in there from where the bearing was worn and the seal was rubbing.

AFAIK at the rear it's no seal just an o-ring, remove the filler plug and blow through the breather pipe cos if it's clogged pressure builds up in the axle which ends up in a leak at a weak point

I did all the brakes on my D2 on Saturday, and when I removed the nsr disc, there was the tellll tale signs and smells of a leaky hub seal, it was in the back of the disc, not saturated, just oily. Is it true that you can't replace the seal, you have to change the entire hub?

Fraid so. Complete hub will have to be changed.
