G'Day,

Just replaced my rear left axle seal in 9" - was leaking oil slightly onto inside of wheel and brake disc. Could visibly see a small slit in the rubber seal when I pulled it out.

Anway........new one still leaks! Bugger.

Is there anything that could be causing this I don't know about?

I found this thread. If you haven't fixed it yet. Might be some help.
Changing diff seals on a 9 inch

I spoke to my diff guys when they fixed my diff. They said 95% of all 9" diffs that come into their workshop are warped. Not badly, but enough to overload one area of the seal which causes them to leak, even after a new seal is installed.

I'd suggest you find a good, reputiable diff place and have them check it. Oh, and by reputiable I don't mean have a flashy ad in a mag.... talk to people and find out who they all agree did a good job. Some of the worst diff places have the biggest ads.

Cheers,
Greg

Common problem with the Borgwarner made 9" discbrake axles. They are basically undersize from new. Apparently when they were assembled in the factory the axle was just cooled and the ring dropped on. The factory manual doesn't even say to replace the bearings it says to replace the axle assembly.


As it is under size the ring that holds the bearing in place moves. This allows the axle to move in and out. Presto a leaking axle seal. In addition the bearings often spins. But don't worry as the caliper should stop the axle from coming out.

You would be lucky to find 1 in 10 diskbrake axles that are in good condition.

In addition the double row bearings are a pos. Police cars were continually having problems with them.

I'm happy to run 11" rims with road legal race rubber on drum brake axle, but I would never consider doing it on a discbrake axle.

Thanks.

I actually just took the 11's and 295's off!!

The smoking oil on the rear disc under breaking is what ticks me off.
