WHEEL ALIGNMENT WHEEL ALIGNMENT FRONT WHEEL ALIGNMENT Specifications (Unladed*l) PRE-INSPECTION 1. Check the tire inflations, and adjust to the recommended d pressure if necessary. 2. lnspect the front wheel bearing play and correct if neces- sary. 3. lnspect the wheel and tire runouts. 4. Inspect the ball joints and steering linkage for excessive looseness. 5. The vehicle must be on level ground and carry no lug- gage or passengers. 6. Measure the height from the center of the wheel to the fender brim. The difference between left and right mea- surement must not exceed 10mm (0.39 in), and the rear measurement must be larger then the front measure- ment by 10-30mm (0.4--1.1 in). Caution The proper caster and camber angle vary depend- ing on the vehicle height. Refer to the following and to page R-9 for the specifications. Inspection and adjustment of wheel alignment must be done with the vehicle unladed*'. . .

Turn the tie rod to provide the correct maximum steering angle. 4. After adjustment, tighten the locknut to the specified torque. Tightening torque: 3539 N-m (3.W.0 kgf-m, 26-28 ftdbf) 5. Adjust the toe-in. (Refer to page R-8.) 6. Verify that the boot is not twisted, and install the boot clamp. Caster Caster is adjusted by turning the front and/or rear adjust- ing cam bolts at the lower arm. Caution Adjust the caster before adjusting the camber. 1. Loosen the front and/or rear cam nuts. 2. Turn the front and/or rear adjusting cam bolts to provide the correct caster angle.

Loosen the front and rear cam nuts. 2. Turn the front and rear adjusting cam bolts the same amount in the opposite direction to provide the correct camber angle. Left wheel Note Turning the front cam one graduation changes the camber about 25' and the caster about 22'. Turning the rear cam one graduation changes the camber about 2' and the caster about 22'.

Remove the steering gear boot clamp. 2. Loosen the left and right tie rod locknuts, and turn the tie rods by the same amount. 3. Loosen the left and right tie rod locknuts and turn the tie rods equally. Both tie rods are right threaded, so turning the right tie rod toward the front of the vehicle and the left toward the rear increases toe-in.
