What torque should a hub nut be?
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.
What is the torque for trailer axle nut?
The spindle is a round piece that protrudes from the axle, holding the hub assembly in place. 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.
Is axle nut torque important?
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.
How tight should 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.
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.
What happens if you dont torque axle nut?
Improperly torqued axle nuts are a leading cause for premature hub bearing assembly failure.
Can you over torque a 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 you overtighten a wheel bearing?
It’s possible to damage the wheel, rotor, and hub assembly. The wheel can come off if over-torquing the nuts/bolts is done.
