The nut on the spindle should be tightened until snug, with no side-to-side play in the hub and then backed off slightly, about maybe a 1/8 of a turn.
What is the torque for a front axle nut?
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.
Can you over tighten spindle 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. The only way to tighten them is with a Torque wrench. …
How important is axle nut torque?
Proper torque secures the axle nut and keeps the proper load on the hub assembly. Second, the proper torque keeps the correct load on a hub assembly needed for longer bearing life.
Can you reuse spindle nut?
Eh, you’re not supposed to reuse them because they have a plastic washer thingy inside them where the threads cut grooves into the nut and kind locks them in place. Most of the time your get one with the hub unit.
What torque should wheel nuts be?
The optimum torque value for your car or mounted rims can be found in the vehicle manual. It depends on the car model, rim size, design (aluminium or steel rims) and number of bolts. It is normally between 110 N⋅m and 120 N⋅m.
Can I reuse an axle nut?
The shop manual warns not to reuse the axle nut, so I trotted off to the parts store for a new one. I’m referring to the special nuts on major components like axle shafts and ball joints where a lost (or loosened) nut can cause accidents, even fatal accidents.
What happens if you over tighten a 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.
Can you over tighten a hub assembly?
Over-torquing leads to excessive load and over-compression of the new bearing. Under-torquing may lead to reduced bearing lifespan and/or the bearing assembly falling apart. A torque wrench is the only correct tool to use while tightening the axle nuts. Some auto technicians opt to use an impact wrench.
Why can’t you reuse a spindle nut?

What happens if your spindle nut is over torque?
It will also leave your spindle nut under or over torque resulting in hub assembly failure. 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.
Why is it important to know axle nut torque?
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. So, it’s important to get it right the first time.
How to tighten the nut on a spindle?
How to tighten spindle nut ? The nut on the spindle should be tightened until snug, with no side-to-side play in the hub and then backed off slightly, about maybe a 1/8 of a turn.
How big of a nut do I need to torque a double nut?
On a double-nut system install a jam nut and torque it to the proper specification, which varies depe nding on the size of the nut. 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.
