[Healeys] End Float

[Bob Spidell]

I think Michael is probably correct; bearings usually make a grinding 
noise when they're worn or broken.

The shop manual has an elaborate process for setting end float on the 
hub involving a dial micrometer and math.  I've had success with 
starting with too few shims--the wheel won't turn at all when the big 
nut is tightened--and stacking them until the wheel turns freely, and 
you can just feel the tiniest of float when you tug on the wheel.  You 
need a few 0.001" shims; the overall stack is usually in the 
neighborhood of 0.030"-0.035".  Do it with just some light oil on the 
bearings at first, then when you've got the stack right load them with 
wheel bearing grease (just on the bearings; don't stuff the whole hub).

Also, torque the snot out of the big nut, and position the hole in the 
end of the axle and the castellated nut such that the cotter pin 
prevents the nut from loosening even a smidge.  I've had the flat washer 
with a tang on the I.D. spin, making the aforementioned grinding noise 
until it wedged itself against the bearing.
