How do I put a wheel bearing on with out a wheel bearing press
In order to replace the rear wheel bearing you will need to find the axle shaft bearings and remove them. They are located at the center of the housing where the ring and pinion gears and at the axle end near the wheel mounting position.
It's wore out, so now it loose and the bearing needs to be replaced O
The shim between the inner bearing and the pinion is critical and if it's lost you need special tools to set the pinion depth. replace the bearings and seal with an new crush sleeve thighten the pinion nut until the sleeve crushes and you can't move the pinion up and down. Then very slowly tighten the pinion nut checking the rotational torque. You will need an inch pound torque wrench, when the preload is correct it should take between 20-25 inch pounds of torque to rotate the pinion. If you get it too tight you need to replace the crush sleeve and start over. Proper bearing preload and gear mesh are critical.

if the play is in driveshaft, replace u joints. if the play is actually in the diff, remove driveshaft and tighten pinion bearing.
