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.
What is the torque setting 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.
How tight should front wheel 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 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.
What are signs of bad wheel bearings?
Top Warning Signs Your Wheel Bearings Need Replacement
- Humming Noise. The most easily identifiable and most common symptom of bad wheel bearings is an audible one.
- Squealing, Growling.
- Clicking Sound.
- Wheel Wobble.
- ABS Failure.
- Uneven Tire Wear.
- Vehicle Pulls to One Side.
- Steering Wheel Vibration.
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 happens if you over tighten axle nut?
An axle nut that is too tight will put too much preload on the hub bearings thus diminishing their life expectancy.
What happens if you over tighten an axle nut?
How long will a wheel bearing last once it starts making noise?
How Long Will a Noisy Wheel Bearing Last? Typically, a wheel bearing should last roughly 1,000 to 1,500 miles after it starts making noise. This doesn’t mean you should keep driving since a noisy wheel bearing is always a risk.
Can you over tighten an axle nut?

Where can I find the torque specification guide?
Ensure that you have the correct torque for the application by referring to SKF 457377 torque specification guide or contact the vehicle manufactures dealer. It is important that you properly torque the spindle nut to ensure optimum bearing life. Under torque of an axle nut will allow excessive movement causing uneven loading and excessive wear.
What happens when an axle nut is over torque?
Under torque of an axle nut will allow excessive movement causing uneven loading and excessive wear. Over torque of the axle nut will cause excessive load and cause the bearing to overheat, this is one of the most common causes for failures.
