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.
