Rear bearings
Well. I already know the answer, but have to ask it anyhow:
With wheels off the ground, and hands at the 9 and 3 position on the tire. When I wiggle the tire back and forth, I can feel slight movement, and visually, the half shaft moves back and forth with the wiggle. New bearings? 'Sho hope not......................

Could be just the bushing. If it's rotted out it will give you movement. If you think it's the side yokes, grab at 12 & 6 and see how that looks. No more than an 1/8" in and out on the side yokes.

Sounds like mushroomed side yokes to me if the half shaft is going back and forth. I was lucky to find a used tight differential for about $300. Might as well service the bearings while everything's apart for another $300 to $600, depending if your cores are salvageable (mine weren't). Just bend over and take your punishment.

A go no go check but not the final word.
You can disconnect the 1/2 shaft and flange from the spindle.
On mine the inner bearing had spun and the spindle hung out several thousands of a thousandths of an inch.
Van steel, Isn't the hand test kind of a half way check? if it fails it needs the dial indicator?
I've always wondered about the tire shaking as a method of checking these .003"-.008" specs.

Hi
I think if you can feel bearing play, you already have other problems, like brake air sucking etc.
Play felt by grabbing the tire is normally yoke play in the rear end which can be as sayed 1/8 each side.

On closer inspection, I only have the play in the drivers side, rear wheel. At 9 and 3 oclock, I have about 1/8" or less of play. But at the 12 and 6 oclock, LOTS of play. When I wiggle in this position, the yoke in the rear end does not move, but the spindle in the wheel sure does
So I either have bearing or spindle wear?
