Wheel Nut Tightening

After the initial tightening, retightening must

be made within the first 500 miles (800 km).

After the first retightening, only normal

inspection of nut tightness is needed.

Check front and rear wheel nut tightness

with a torque wrench. All disc wheels for

Volvo vehicles have a tightening torque of

610 Nm (450 ft-lb). Tighten the nuts in the

correct sequence. For spoke wheels, check

the manufacturer’s specifications. Inspect

bolts and nuts for signs of wear or cracks.

Make sure that the bolts are not bent.

8 and 10–stud wheelnut tightening

sequence.

DANGER

Failure to properly torque-tighten the

wheel nuts can result in the breakage of

wheel studs and the subsequent loss of

wheels. This can lead to loss of vehicle

control and serious personal injury or

death.

This check tightening is particularly

important when rims or brake drums are

newly painted. Paint can flake off from these

surfaces, causing the nuts to lose their grip

and the wheel to loosen.
