Outer Limits 4x4 Board

Have the front diff out and was looking for suggestions from you guys as to which grease to use to repack the axle swivels please.

Also I have noticed that many workshops don't use diff gaskets anymore when re installing diff centres.
can someone tell me what they use, it seems to be some type of silicone based product. Is there a special type to use on diffs or can I just use any product.
Thanks guys

Any RTV silicone, as long as it's oil resistant. For grease, use molybdenum(sp), also called CV grease. Grey/black sticky stuff

Thanks moose,
