use a GOOD quality bearing grease on the seal as well as the Axle splines
that go into the hub. To install the axles you need to be VERY CAREFULL
that you do not damage the seal. Use a long 3/8 NF bolt 5” or longer,
threaded into the center hole. This will allow you to hold something as you
slide the axle into the housing. Because the hub does NOT get any
lubrication from the gear oil they MUST be prelubed WELL during
assembly. IF you do not use a generous amount of lube on the splines and
axle seal the warranty on the hubs WILL be VOID!!!
