FYI,, Wheel bearings are hard to buy at the local auto parts store,,,,,BUT if you know the true part numbers it's a snap.
Most all 3500lb. axles use the same bearings and seals,Hear is what to ask for.
NAPA #s SET#4
NAPA #s SET#17 for the bearings
National seal#473336,,This is the proper double lip seal
Any part counter key puncher can cross reference these numbers
