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.
How much torque does an axle nut need?
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.
What is the front hub bearing torque specs?
The torque specifications for GM wheel hubs generally range between 107 to 225 foot-pounds , depending on the year and model.
Can you over tighten an axle nut?
It’s possible to damage the wheel, rotor, and hub assembly. The wheel can come off if over-torquing the nuts/bolts is done. It happens, but it doesn’t happen a lot. The only way to tighten them is with a Torque wrench .
Do you have to torque the axle nut?
Proper torque secures the axle nut and keeps the proper load on the hub assembly. ... 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.
What is the torque setting for a wheel bearing?
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 .
How tight do you tighten front wheel bearings?
The nut on the spindle should be tightened until snug , with no side-to-side play in the hub and then backed off, about a quarter of a turn. The nut finger should be tight until the castle nut or cotter pin is used.
What should I torque my wheels to?
| Hardware Bolt or Stud Size Typical Torque Range in Ft/Lbs Minimum Number of Turns of Hardware Engagement | 14 x 1.25 mm 85 – 90 9 | 7/16 in. 70 – 80 9 | 1/2 in. 75 – 85 8 | 9/16 in. 135 – 145 8 |

What happens if you tighten axle nut too tight?
An axle nut that is too tight will put too much preload on the hub bearings thus diminishing their life expectancy .
How do I tighten my axle?
Tighten the axle nut with a socket and torque wrench; torque the axle nut between 15 to 20-ft pounds of torque to preload the axle bearings. Rotate the hub eight to 10 revolutions by hand to fully seat the bearing races. Loosen the axle nut until it is freely loose, then finger-tighten the axle nut.
What happens if you over torque a wheel bearing?
“ Excessive preload will cause excessive friction and the bearing will run hot, compromising lubrication and eventually leading to flaking (material coming off) at the large end of the rollers/races,” he says. “On the other hand, adjusting the bearing too loose causes excessive looseness and vibration in the system.
What are the most common axle nut sizes?
