On some wheel bearings sets and hub units, the axle nut secures the outer flange to a CV joint or stub axle. As the nut is tightened, it pulls the flange and axle together to set the preload of bearings. These axle nuts will have specifications as low as 130-foot pounds and as high as 300-foot pounds.

How tight do you tighten CV axle nut?
What is the torque on a hub nut?
For some hub units, the final torque specification can range from 150 to 350 ft/lbs depending on the application. Accurately tightening nut is critical to set the load paths for the bearings. But you must trust your torque wrench. Torque wrenches designed for lug nuts typically have an upper limit of 190 to 200 ft/lbs.
What torque are wheel nuts on a BMW 3 Series?
Anything between 85 to 100 ft lb is good. I take a higher number just in case. But if some one accidentally sets torque to 140 ft lb, it is not going to kill the rotor. Lug nut is not as critical as cyclinder head bolt.
Do I need torque wrench for axle nut?
Many technicians use an impact gun when installing an axle nut on a wheel hub bearing which not only overtightens the bearing but can also cause premature wear to the hub assembly. MOOG recommends using a torque wrench to tighten the axle nut accurately.
Do you need to torque axle nut?
Axle nuts plan an important role in the wheel end, and properly torquing the axle nut is an important part in wheel bearing replacement.
Can you over torque a CV axle?
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 axles be?
How tight should my thru axle be? Typically, thru axles should be tightened to 12-15Nm (Newton Meters) of torque. This is just enough torque to secure the axle so it does not come loose while riding. You should never tighten your axle as tight as possible.
How tight should axle 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.
Is it OK to reuse axle nut?
Whichever style is on your vehicle, make sure you buy a new nut after removing the old one. The old nut will not hold the proper torque a second time. Don’t even think about “re-deforming” the old nut in your bench vise—it won’t work. New axle nuts cost about $3 and ball joint nuts usually less than $1.
Is the torque on an axle the same as the torque on the wheel?
In both cases the torque is the same.
What torque should wheel bolts be?
It is normally between 110 N⋅m and 120 N⋅m. If you change the rims on your car, you will find the new torque values in the rim certificate.
How tight should BMW lug nuts be?
Once you remove the lug bolts and torque them again, 88ft. lbs. is the recommended BMW Torque setting.
Should I put anti seize on axle nut?
Do not use grease, anti-seize compound or other lubricants when mating the CV axle shaft to the wheel hub assembly. Clean and remove all corrosion, rust, burrs and any other debris from the CV axle spline end, wheel hub assembly and steering knuckle.
Can I remove axle nut without impact wrench?
Do you need washer for axle nut?
Yes, there should be a washer of some type between the spindle nut and the bearing on your trailer. The washer protects the back side of the bearing from the edges and points on the back side of the spindle nut.
What is the torque for hub assembly?
Does thread locker change torque?
When we apply threadlocker to a bolt, we tighten it by giving a tightening torque.
Should you be able to wiggle your CV axle?
The CV shaft is connected to the trans-axle and wheel. Unless the wheel is off the ground and the car in neutral it should not move. Movement is a possible sign of wear.
Is it better to over or under torque?
Over-tightening can cause damage to the fastener, and under-tightening can result in making the item you are attaching or assembling structurally weak and potentially unsafe for use.
Does CV axle affect acceleration?
Damaged Inner CV Joints Can Cause Vibration on Acceleration Damaged inner CV joints cause vibrations on acceleration and are very difficult to diagnose because the damage is so inconspicuous.
What happens if you torque too much?
Too much force can cause a technician to strip threaded fasteners or stretch bolts beyond their limits, which can result in loose nuts or cause the bolt to crack and break.
What happens if you over tighten thru axle?
Keeping the axle under-torqued is dangerous, and over-torquing it might damage the fork/frame dropouts.
How much wheel bearing play is OK?
As a rule, there should be no perceptible play in the wheel bearing if you are pulling and tugging on a wheel 12 and 6 o’clock, but up to . 010 inch of. play in the front bearings may be acceptable on some old vehicles cars and trucks with adjustable bearings.
Can you over tighten a wheel bearing?
Over-tightening can damage the lug nuts, wheels and hubs – and worse, result in a wheel-off situation.
