I think you are making the best decision, by pulling the diff cover. This
way, you can inspect everything, and fully clean the magnet good. I use
Permatex RTV Ultra Blue, and used almost and entire tube this last time I
did mine; I think I didnt use enough last time and didnt allow it to cure,
which caused it to leak. I found that a wire brush attachment on my Dewalt
cordless drill works simply awesome for removing all of the old RTV, on both
the diff cover and on the diff housing. Be sure to use plenty of 'Brake
Cleaner' on the internals(of the diff housing), as you want to have as close
as an an 100% oil free area as possible. This is another reason I had a diff
fluid leak, cause there was some diff fluid still within the diff, which
leaked down and did not allow the RTV to fully cure to the metal surface. I
found that WalMart actually is alot cheaper for Brake Cleaner than any auto
part store around. I recently paid $1.77 per can. I used 4 cans on the rear
diff alone, yes 4 cans, when cleaning out the diff housing this last time.
This way, I was absolutely sure not to have any oil residue anywhere. I
applied the RTV to the diff cover and also on the diff housing, and let it
cure for about 2-3 hours. I tightened the diff cover bolts down just snug,
so a tiny bit of RTV oozed out. After the 2-3 hour curing time, I torqued
the bolts down to 30-35 foot pounds. You do not want to tighten the diff
cover bolts down so much to the extent that the RTV gets pushed out, and
then the diff cover is actually touching the diff housing; metal on metal
doesnt provide for a good seal. Let the RTV do its job. Hope this helps you
out.
