Pulled the diff cover off today while waiting for the truck to cool off
enough to do the front steering stuff. Got the diff mating surfaces and
the cover really clean, cleaned the surfaces with brake cleaner and let
'em dry, then used a whole bunch of orange RTV on it. It took me
forever to finish the front steering stuff so it got to sit a good 8
hours and cure before I put the gear lube (this time with a tube of LSD
additive to be safe) into it. Seems to be ok so far.
BTW, don't buy anything from ok4wd.com. I ordered that gasket for the
rear diff I was talking about late in the evening on 7/30, paid extra
for 2 day shipping, and it's still not arrived. This is despite an
e-mail status update from them on 8/3 that it finally shipped 2 day
shipping. I sent an e-mail asking for the tracking number and of course
no one has bothered to reply. Sheesh. Talk about not wanting return
business.
