Subject: [TR] Grease in the rear drum

Pulled the rear drum on the TR3 and found grease contaminating it inside.  At first I thought I had a differential oil leak into the hub, but because it's more like grease, is it possible that I've overpumped grease at the axle bearing?

Possible but not as likely as gear oil in my opinion.  I think excessive
grease in the hub should get into the axle unless the hub seal has failed.

Did you smell what you found?  You might compare its smell to grease &
whatever you are using in the diff.

I experimented with (inadvertently) ignoring this.  I had not noticed my
axle was leaking until I lost the rear brakes entirely (in Las Cruces, New
Mexico).  Braking noise got my attention.

Upon removing the drum I found that the brake shoes had fallen off the
carriers and were lying in the bottom of the drum.  Apparently hot gear oil
will dissolve the glue that was used on the shoes.

Clamped off the rear brakes and drove home (300 miles) using just the
fronts.

I thought I would mention this just for a laugh.  I was told by someone 
somewhere sometime that his father had an MGTD.  when the rear seals go on 
that, they leak oil into the brake shoes.  when this happened, he would heat 
the shoes on the grill, and the oil would seep out.  then he would put them 
back on the car.

Replace the shoes!!!!!!!

I have a guy in our club who puts them in a pot of boiling water and boils
the contaminants out and re-uses them.

I replace them.
