Forget the gasket - use RTV
Forget repacking the bearings. The bearings are not grease
packed. They are lubed from the diff oil. Don't even worry
about washing them. They are pressed into the housing. You
almost always damage them when removing making replacement
necessary. They ride directly on the axle shaft with no
inner race. Don't screw aroung with them at all unless you
have to replace a leaky seal or have a bad bearing. There
is no maintenance required unless there is a known problem.
The only maintenace is to remove the cover to dump the
fluid, replace cover and refill with fresh diff oil per
OK, right on, i think theres a gasket there now, or maybe not. I'll
just use straight RTV.
I have to do an axle seal anyway, so i might as well do both seals i
think... so long as its not a HUGE deal
If you have to do one seal, do both. It's not that bigger
deal. Check the bearing surfaces of the axle shaft for any
signs of pitting or spalling where the bearings ride.
Service the bearings if you see any problems. If the axle
shaft is damaged, you will need to uses a repair setup made
for the purpose or install a new axle shaft and bearings.
From what you say, you only need new seals. This is also a
good time to inspect/replace your parking brakes as the
axles have to be pulled to service them. Don't do anything
with the bearings or axles unless there is a problem. I am
also a fan of leaving the pinion seal alone unless you have
a problem beacuse you need to know a bit about what you are
doing and get it properly tightened which also adjust the
preload on the pinion bearings. This can be critical. Do
use the best gear lube you can find to refill the
