The advice I got on my F350 was to use the Permantex Differential gasket gunk and forget the gasket. It's worked so far on both differentials

In a pinch, I've used silicone window caulking or manhole mastic in similar applications.
And I've heard the "Right stuff" gasket maker works awesome.

But that was't the question and reusable rubber gaskets are a nice departure from smearing gasket goo on surfaces.

You sure can as this is the method most dealers use. Unless there's a drain plug.

It's DA CHITZ!!! NEVER had a leak using it.

I do reuse my gasket on my 15 DRW RAM.

But you won’t be able to have a look at the ring and pinion and clean the magnet. Not good IMHO.

Even when I was running a MagHytec that has drain and fill plugs I always removed the cover for inspection.

you'll have the magnet/plug out to add fluid...so yes you can clean the magnet.

The cover is 14 bolts. It is a metal and rubber, reusable seal, so unless it is damaged in some way, it should be just fine. Carefully wipe it off and examine both sides of it. New ones are expensive, about $45 or so. There are no drain plugs and you should pull the cover and examine the insides.

Do NOT use any sealer on this seal, just wipe it off and possibly wipe a fresh film of gear oil on it.

GM uses the same basic rear end on many models but they use a throwaway gasket.
