Slow drip from rear diff...

What's the best material for sealing differentials? I've got a slow constant drip coming from the rear, and a small drip from the front after a days drive. Is there a fail-proof material to use to seal them buggers?

What's the best way to condition the surface when preparing to reseal them?

I've got guards in place (see below), is there any other tips/tricks to get a flush seal when tightening them? I use a star pattern approach, tighting them down snug. Let it sit for thirty minutes, retighten each one. Let it sit for another thirty minutes, and do a final set. It's about the best way to do it, right? Temperature is about 70-80 deg when doing this.

Try the Lube-Locker gaskets. I've had good luck with them. 4WD Hardware sells them.....and I'm sure many other places. They run about 17.00 ea. I think. Just clean the surfaces of the cover and diff with steel wool/ scotchbrite or some thing similar making sure to get all the old gasket/sealers off

I like to use Blue RTV (cuz the color matches my eyes). Clean with scotchbrite, chase all the bolt holes, apply good bead of RTV, quick tighten (snug) all the bolts, wait over night, torque bolts to spec, fill.

you do have pretty eyes lomod [img]/ubbthreads/images/graemlins/grin.gif[/img]

but also give the mating surface a spray of brakeclean and whip it down to get all the grease/oil off......also make sure you circle the bolt holes with the RTV (blue, black or gray)

to elaborate on Galens point here. if you, or a PO have used RTV on a regular basis to seal your diff cover, there could be RTV on teh end of your bolts and in teh bottoms of teh holes for the bolts. if so, you won't be able to tighten teh bolts all the way down. they will bottom out on teh old RTV. this is where a dental pick and an air gun come in handy. pick them and then blow them out.

Use "gear lube RTV", don't pick your nose, add oil AFTER you tighten the bolts.
Brent, John, and Galen ya'll are sick!

Beat me to it Galen... I immediately thought of ol' Calvin when I read Brent's post.

"If you follow too close, I'll flick a <font color="green">booger</font> on your windshield!" What a great bumper sticker... gross, but funny as they come.
