Question: Can wheel nuts be overtightened?
Answer: Wheel nuts can be overtightened and snapped when using a rattle gun, take care. Once the nut has stopped moving, it is tight.
A more accurate method is to refer to Owner Manual or Wheel Specification for the maximum torque settings below.
- 7/16″ Stud – 70-80 ft-lbs – 108Nm
- 1/2″ Stud – 75-85 ft-lbs – 115Nm
- 9/16″ Stud – 135-145 ft-lbs – 196Nm
- 5/8″ Stud – 175 ft-lbs – 237Nm
- M12 Stud – 75-85 ft-lbs – 115Nm
- M14 Stud – 135-145 ft-lbs – 196Nm
New wheels should be torqued after 150km, this should be done as the clamping loads would change due to thermal stresses.
When torquing the wheels, this should be done when the wheels are cool and have reached ambient temperatures.
Never torque a wheel when hot, always wait until the wheel cools down.
Loosen wheel nuts completely, then tighten and torque wheel nuts in the correct sequence.
Travelling rough outback road has a few drawbacks.
One of which is wheel nuts becoming loose on rough and corrugated roads.
Broken wheel studs caused by wheel nuts falling off is typical yet unpublicised.
We recommend checking all wheel nuts every morning before even starting the car engine.
I use a battery rattle gun. It does a quick job and ensures tightness.
Spares are essential when travelling the Outback regions
For me, it is very comforting to know I have the following spares on board before heading into the outback:
- Bearing Kits
- Shackle Bolts and bushes
- Spare Hub and
- Square Stub Axle to suit
- Ubolts long enough to clamp the stub axle onto the existing shaft (in case of axle profile breakage).
