Checking the Wheel Nut
Important: In addition to the maintenance interval in this manual, check the wheel nut torque the first 50 to 100 miles (80 to 160 km) of operation after a wheel has been removed and installed.
Note: On each wheel stud, the end that faces away from the vehicle is stamped with an "L" or an "R," depending on which side of the vehicle the stud is installed. Studs stamped with an "L" are left-hand threaded and are installed on the driver's side of the vehicle. Studs stamped with an "R" are right-hand threaded and are installed on the passenger's side of the vehicle.
When checking wheel nuts on a dual disc assembly, remove one outer nut at a time, tighten the inner nut, then reinstall the outer nut. Repeat this procedure for all of the inner wheel nuts in the sequence shown in Fig., Fig., or Fig.. Then, tighten all of the outer wheel nuts in the same sequence.
Caution: Too little wheel nut torque can cause wheel shimmy, resulting in wheel damage, stud breakage, and extreme tire tread wear. Too much wheel nut torque can break studs, damage threads, and crack discs in the stud hole area.
Tighten the wheel nuts.
-
On 6-stud, stud-pilot hubs, tighten the wheel nuts 450 to 500 lbf·ft (610 to 678 N·m). See Fig. for the tightening sequence.
-
On 8-stud or 10-stud, hub-pilot hubs with 20-mm studs, tighten the wheel nuts 280 to 310 lbf·ft (380 to 420 N·m). See Fig. or Fig. for the tightening sequence.
-
On 8-stud or 10-stud, hub-pilot hubs with 22-mm studs, tighten the wheel nuts 450 to 500 lbf·ft (610 to 678 N·m). See Fig. or Fig. for the tightening sequence.

Note: Wheel nuts for 20-mm stud hubs require a 1- 3/16-inch (30-mm) socket. Wheel nuts for 22-mm stud hubs require a 1-5/16-inch (33-mm) socket.
