If you put a floor jack under the spindle to put say 100lbs force or more on it. The bearing will no longer turn IF you have enough shims in place.
That confuses me! Placing a jack under the spindle has the same effect as having the car on the ground (weight on the wheels). I've never heard of a car messed up enough that the bearing shell will turn under these circumstances.

By contrast, if the car is on the ground and you raise a jack under the axle the bearing shell SHOULD be able to be turned. If you use a enough shims to prevent it from turning then you are creating friction between the top of the axle and the spindle flange which will certainly inhibit steering.

With everything shimmed and the car back on the ground, you MUST be able to get a feeler gauge between the top of the axle and the spindle flange all the way around.
