The Stovebolt Site Forums The Shop Area General Truck Talk I have grease in my rearend???

i've heard of sawdust in the rear end to make it tighter and quieter, but hadn't heard of grease. someone who knows better than i, could you please let us know of a valid reason for using grease in the rear diff cause i'd sure be interested to know?
and, does it work? i know it wouldn't work in the tranny cause of the bearings. not sure if it's a good idea in the rear end though.
thanks
