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 tight should axle bearing nut be?
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.
Do you need a torque wrench to change wheel bearing?
OEM and bearing manufacturers always recommend using a torque wrench for installation. During removal, an impact wrench can damage the axle nut threads and shock the CV joints. It can also create a false sense of security when adjusting a nut or bolt, which may be under or over torqued.
How tight should castle nut be on wheel bearing?
Expert Reply: 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 happens if you over tighten an axle 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.
What happens if I over torque an axle nut?
Is it OK to reuse an axle nut?
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. Your family’s safety is worth far more than that.
Can you over torque an axle nut?
How do you set preload on a bearing?
The simplest method of applying preload is to use a wave spring. The spring acts on the outer ring of one of the two bearings. This outer ring must be able to be axially displaced. In the diagram below, the bearing arrangement comprises a preloaded, single-row, deep groove ball bearing at each end of the shaft.
Can you overtighten a hub nut?
Avoid Overtightening – Use the Right Tool 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.
