Thanks for all the posts to the list on this subject. I'm about to repack my
wheel bearings for the
first time and welcomed the information.
I never understood all that extra grease in the hubs. Good to know it's not
necessary.
Some time back there was a discussion about the technique for packing them. How
to scoop the grease
in with your hand/fingers etc. Anyone care to refresh my memory on all that, or
just pack it in any
old way?
Thanks,
Don Malling
