Where do I purchase and what Front Wheel Bearings do I need?
Cinnibar and Gateway sell 'matched' sets of Timken wheel bearings. These
include a spacer ring that installs between the two cones whose thickness
dictates the assembled axial clearance of .0095". The bearings will have
this hand etched on the spacer. They cost about $80 per set including
inner and outer seals. (CAUTION: Do not mix these bearing parts with any
others as this will change the clearances.)
Why is that important you ask? Good question. The outside of the hub
should measure from 2.0015" to 2.0020". The inside diameter of the bearing
that I have, measures 1.970". If I were to press that bearing on a hub
with maximum outside dimension of 2.0020" there would be a.032"
interference fit. Thats pretty tight and would reduce the axial clearance
of the bearing by some amount. How much? I don't really know, however the
cinnabar engineers have run tests on the various bearings with maximum and
minimum dimensions for both the hub, knuckle and bearing and decided that
in the worst case of each, an axial clearance of .0095" is the minimum
clearance that can be safely used.

Others to use in a pinch: (same bearings but not clearanced for our
application) Use at your own risk!!

What about rear bearings and seals?
Checker had all the parts in stock and were cheaper than AutoZone. They
carried Chicago Rawhide (CR) which is an old line US manufacturer. When
you look closely at the inside bearings you see "Mexico" on them!! The
outside bearings are made in Germany. The outside cones and seals made in USA.
The seals are Part No. 21771 and costs $3.89 each.
The inner cone (cup) is LM501310 , $3.89.
The inner bearing is LM501349 , $8.29.
The outer cone is BR15243, don't remember the cost.
The outer bearing is 15103-S, don't remember the cost. Emery Stora
inner seal is Federal 5123, national 5123, NAPA 47471, or Delco 290-19.
OUter seal is Federal 5109, National 5109, NAPA 47470, or Delco 290-17 Tom
