Servicing bearings-full floating

[packmaster2r]

I have a 1998 2500HD with full floating rear axle. The double roller rear wheel bearings are lubed by the differential oil.

Should these also be packed with grease when servicing ? My "aftermarket" (Haynes) service manual says yes, but this seems uneccessary since the bearings are constantly immmersed in fluid. I can't see any grease in them now, though I suppose it may have washed out since the last brake job.

I don't have a GM manual and would sleep better if I new for sure !

I don't grease mine, but I do make sure and tip the axle so that oil distributes to each end prior to driving...

Thanks, I appreciate your input. Always nice to have real world experience when in doubt.

I changed many off these bearings over the years I'm fleet tech when I change these I dip the bearings in oil than install when I put the hub on I put some one in the pocket area between the bearings. Then normal just park the opposite side up on a block of wood or curb to allow lube to run out to bearings, make sure to recheck gear lube level after truck has set on level surface over night VERY IMPORTANT
