I agree that the instructions are a bit confusing. Without having
engineering drawings of the hub or taking precise measurements of the hub
and bearing, one would never actually know if the bearing is completely
seated against the abutment shoulder when the bearing is pressed in to the
dimension specified. My thinking was that if the spacer had to protrude
0.001 to 0.004 inch above the hub flange surface, then the only way to
accomplish that would be to press the bearing in until the measurement was
achieved, and let the far side of the bearing outer race be wherever it was.
Whatever, it has been 56,000 miles since I did this job and no problems so
far.

These instructions have always cornfused me. If the bearing is pressed
against the "... abutment shoulder in the hub
..." there won't be much adjustment possible (unless you have a press strong
enough to compress the hardened steel
bearing race, and distort it). The only way to adjust the 'protrusion'
would be to use differing width spacers. I've
always interpreted this as 'make sure the spacer is at least a slight bit
above the face of the hub.' If it isn't, you
probably have an ill-fitting bearing.
Or am I missing something?
