What is the torque for wheel bearings?

What is the torque for wheel bearings?

Generally, jam nuts less than 2-5/8″ should be torqued to 200-300 lbf-ft; nuts 2-5/8″ and over should be torqued to 250-400 lbf-ft. See chart for exact torque specification. The final step is to use a dial indicator to verify the end play or free movement of the tire and wheel assembly along the spindle axis.

What are the torque specs on the front hub assembly?

The torque specifications for GM wheel hubs generally range between 107 to 225 foot-pounds, depending on the year and model.

What is the torque on an axle nut?

For a double nut or jam nut system, bend the lock tab or install the set screw after the outer nut is torqued to 200 ft-lbs. For one-piece spindle nut systems, torque the nut to a minimum of 300 ft-lbs.

Do wheel bearings need to be torqued?

The wheel bearings are responsible for allowing the wheels to be able to turn properly on the spindle. The wheel bearing is held in place by an inner and outer nut. Both of these nuts have to tightened and torqued for the wheel bearing to be able to work properly.

Do you need to torque axle nut?

Proper torque is critical for two reasons. First, it secures the axle nut so it won’t work itself loose and back off. Second, the proper torque keeps the correct load on a hub assembly needed for longer bearing life. When you’re removing the wheel hub nut, you can use an impact wrench to speed up the job.

Can you over tighten an axle nut?

An axle nut that is too tight will put too much preload on the hub bearings thus diminishing their life expectancy.

Do you have to torque axle nut?

OEM and bearing manufacturers always recommend using a torque wrench for installation. During removal, an impact wrench can damage the axle nut threads and shock the CV joints. Also, in almost all cases, use a new axle nut.

Is it bad to over tighten axle nut?

No. Over tightening won’t put more of a strain on the bearings in this sort of design. You should’ve torqued those nuts down quite a bit.
