Let me add a couple terms here to help clarify.
The caged ball bearings that have no bias as to direction of side load
(and in fact will tolerate *very* little side load) are generally called
radial ball bearings. This is what Barnie and Ken are describing.
Laurie is refering to ball bearings designed to take a side load as well
as a radial load. These are called angular contact ball bearings. They
have a much higher tolerance for side loads, at a slight cost to radial
Thrust bearings are strictly for axial loads and have no tolerance for
I haven't taken the hubs off of my A yet to swap them out, but I am
surprised to find that there are only radial ball bearings in there. I
expected to find angular contact bearings when I take it apart. What
takes the side loading in the front suspension?
