2007 GMC Sierra 3500 HD Camber and Alignment Kit

You should install the alignment equipment according to the manufacturer's instructions, jounce the front and the rear bumpers 3 times before checking the wheel alignment, measure the alignment angles and record the readings and then adjust alignment angles to vehicle specification.

The procedure is to determine the caster angle, determine the positive camber or negative camber angle, remove the pinned adjusting cam insert, loosen the upper control arm cam adjustment bolts, and adjust the caster and the camber angle by turning the cam bolts until the specifications have been met, hold the cam bolt head to ensure the cam bolt position does not change while tightening the nut and then verify that the caster and the camber are still within specifications.

You should inspect the tires for the proper inflation and irregular tire wear, the runout of the wheels and the tires, the wheel bearings, the ball joints and tie rod ends, the control arms and stabilizer shaft, the steering gear, the struts/shock absorbers, the vehicle trim height, the steering wheel, and the fuel level.

The recommended torque is 75 N.m (55 lb-ft).

You should set the tire pressures to the pressure shown on the certification label, check the fuel level, make sure the passenger and rear compartments are empty, make sure the vehicle is on a level surface, make sure that the system is functioning properly, make sure that all doors, liftgate/trunk, and the hood are securely closed, check for installed aftermarket accessories or modifications that could affect trim height measurements and then remove the alignment rack floating pins.
