WHEEL LUG NUT TORQUE - SERVICE TIP
This bulletin supersedes TSB # 03-50-003.
DESCRIPTION:
This bulletin provides the proper procedure for torquing the wheel lug nuts.
CAUTION:
Do not use an air impact tool for wheel lug nut installation without the applicable torque limiting socket.
Air impact tools can generate up to 300 lb-ft (400 Nm) of torque. This amount of torque exceeds the Hyundai wheel lug nut torque specification. Overly
torqued and/or unevenly torqued wheel lug nuts may cause the following:
^
Distortion of the wheel hub
^
Distortion of the brake disc
^
Increased brake disc runout
^
Brake vibration and pulsation
^
Damage to the wheel rim
^
Damage to the wheel lug 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,
preventing over tightening or uneven tightening of the wheel lug nuts.
