What should wheel bearing retaining nut torque be?
The design demands that the wheel bearing retaining nut be tightened to a specified torque of 45 Ft-lbs to 70 Ft-lbs. This pre-stresses the stub axle by means of the spacer, and thus enables it to carry the suspension loadings without fracturing.
What’s the best way to replace front wheel bearings?
Then pack the bearings – pressing grease in from one side only until it oozes out the other side, if you try to speed things up by pressing it in from both sides you will trap air and get premature wear. Then fit the grease seal, groove facing into the hub. Just pack the groove with grease, not the space between the bearings.
What is a face adjusted front wheel bearing?
A “face adjusted” bearing is one that has been surface ground so that the surfaces that are in contact with the hub and the spacer are flat and parallel to each other whenever both races are in contact with the bearings as they would be when properly installed.
Why does a stub axle have a gap?
When the bearing radius is smaller than the radius of the stub axle, the bearing does not fit against the flange. The contact between the bearing and the flange face is designed to help support the axle load. Hence, a gap would provide a flex point which could easily lead to failure of the stub axle.
What to look for when replacing a wheel hub?
That can cause premature wheel bearing failure. When the old hub is removed, use the opportunity to inspect the knuckle for damage. Look for corrosion and make sure a bore gauge rotates in the bore without any trouble. Also, before installing the new hub check it’s runout.

What happens if you over tighten an axle shaft nut?
Loosen axle shaft nuts – The large amount of instant torque can damage CV joints Tighten any nuts – It is very easy to over-tighten any nut with an impact wrench. 2. Failing to Use the Provided Self-Staking Nut
What should my hub runout be before replacing it?
Also, before installing the new hub check it’s runout. As a rule of thumb, on a modern vehicle, hub runout should be between .000″ and .0015″. If you take the time to verify the hub before installation, any other runout issues will be easier to troubleshoot.
