On the topic of rear axles - what does one recommend for the rear axle wheel bearings regarding lubrication. Mine came out greased. I figured the rear diff oil would lubricate them. Should I grease them, or dip them in diff oil, or fill the hubs with diff oil?
A full floating rear axle is lubricated with the rear end oil. If someone put grease in the hub bearing it was because the oil seal was leaking. Installing the Speedi Sleeves should take care of the problem. On my truck I cleaned the grooves and filled it with Devcon Titanium and sanded it down smooth. Have over 6300 miles on it and no leaks. When you fill the rear axle raise one rear wheel as high as you can go to allow the rear end oil to flow into the hub. After 30 minutes or so do the other wheel. Then recheck your rear end oil.

Hope this help.
