What torque should a hub nut be?
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 is the torque for hub assembly?
GM Automobile Torque Specifications 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 spec for wheel bearing nut?
For one-piece spindle nut systems, torque the nut to a minimum of 300 ft-lbs. Do not back off the spindle nut. Engage any locking device that is part of the spindle nut system. If the locking device cannot be engaged when the nut is at 300 ft-lbs, advance the nut until engagement takes place and the nut is locked.
How much torque should a hub bearing have?
Lubricate the wheel bearing with clean lubricant of the same type used in the axle sump or hub assembly. Tighten the adjusting nut to a torque of 200 ft-lb while rotating the wheel hub assembly. Back the adjusting nut off one full turn. Re-torque adjusting nut to 50 ft-lb while rotating the wheel hub assembly.
How much torque should an axle nut have?
Also, in almost all cases, use a new axle nut. with no more than 15 to 20 ft. lbs. of torque while rotating the wheel to make sure the bearings are seated.
Can you over tighten a hub 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.
How tight should bearings be?
For context, the tolerable end-play for truck wheel bearings is the same: 0.001 to 0.005 inches, also expressed as 1 to 5 mil or 0.025 to 0.127 mm. In other words, it’s perfectly acceptable to adjust wheel bearings so that they are just a little bit loose, but not too loose.
Do you have to torque the 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. Torque specifications can be different, even for the same hub, if it’s multiple applications.
Can you over tighten axle nut?
Should I torque axle nut?
Torque the axle nut to manufacturer’s specifications. Do so while vehicle is raised and the hub assembly is unloaded. Once the vehicle is off the ground, it is safe to proceed with torqueing the axle nut. Also be sure to have someone else hold the brake pedal down while you torque the axle nut.
