Subject: WHEEL LUG NUT TORQUE - SERVICE TIP
DESCRIPTION:
This bulletin provides the proper procedure for torquing the wheel lug nuts.
NOTE: Use of an air impact tool for wheel lug nut installation without the applicable torque limiting socket is not recommended.
Air impact tools typically used for wheel lug nuts can generate up to 300 lb-ft (400 Nm) of torque. Overly torqued and/or unevenly torqued wheel lug
nuts may cause:
-
Distortion of the wheel hub
-
Distortion of the brake disc
-
Brake disc runout
-
Brake vibration and pulsation
-
Damage to wheel rim
-
Damage to the wheel nuts and lugs Steering wheel vibration and shimmy
PROCEDURE:
All wheel lug nuts should be tightened to specification using a torque wrench or using an applicable torque stick (torque limiting impact socket) supplied
by ACCUTORQ (TM) (or equivalent) on a 1/2 inch drive impact tool. The "ACCUTORQ (TM)" lug nut socket limits the torque of the air impact tool,
