2 SA5 If the vehicle height is not as specified, try to adjust it by pushing down on or lifting the body. 2. INSTALL CAMBERCASTERKINGPIN GAUGE OR POSITION VEHICLE ON WHEEL ALIGNMENT TES- TER Follow the specific instructions of the equipment manufacturer. Z INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION Camber, caster and steering axis inclination: Camber 0 08 ± 45 (0.14 ± 0.75 ) 0 06 ± 45 (0.10 ± 0.75 ) 0 17 ± 45 (0.28 ± 0.75 ) 0 16 ± 45 (0.26 ± 0.75 ) Caster (Except air suspension models) 2 56 ± 45 (2.93 ± 0.75 ) 2 59 ± 45 (2.98 ± 0.75 ) 3 02 ± 45 (3.04 ± 0.75 ) 2 36 ± 45 (2.60 ± 0.75 ) 2 38 ± 45 (2.64 ± 0.75 ) 3019

3 SA6 Caster (Air suspension models) 3 17 ± 45 (3.28 ± 0.75 ) 3 20 ± 45 (3.33 ± 0.75 ) 3 21 ± 45 (3.35 ± 0.75 ) 2 55 ± 45 (2.91 ± 0.75 ) 2 56 ± 45 (2.93 ± 0.75 ) Steering axis inclination ± 45 (10.24 ± 0.75 ) ± 45 (10.27 ± 0.75 ) ± 45 (10.09 ± 0.75 ) ± 45 (10.11 ± 0.75 ) If the steering axis inclination is not within the specified values, after the camber and caster have been correctly adjusted, recheck the steering knuckle and front wheel bearing for looseness. 4. ADJUST CAMBER AND CASTER (a) Loosen the front and/or rear adjusting cam set bolts. (b) Adjust the camber and caster by turning the front and/or rear adjusting cams (See adjustment chart). HINT: Try to adjust the camber and caster to the center of the specified values. R

(1) Find the applicable wheel alignment standard value for the particular model. (2) Mark the selected standard value on the adjustment chart. Camber: 0 08 (0.13 ) Caster: 2 59 (2.98 ) (3) Measure the present wheel alignment value with the vehicle unloaded. (4) Mark the measured present value on the adjustment chart. Camber: 0 20 (0.33 ) Caster: 2 59 (2.98 ) (5) As shown in the example chart, read the distance from the measured value to the standard value, and adjust the front and/or rear adjusting cams accordingly.

(*1): Air suspension models only If the toein is not within the specified values, adjust the rack ends. 6. ADJUST TOEIN AND WHEEL ANGLE (a) Remove the 2 clips. (b) Loosen the tie rod end lock nuts. (c) Turn the right and left rack ends by an equal amount to adjust the toein. HINT: Try to adjust the toein to the center of the specified values. R13228 (d) Make sure that the lengths of the right and left rack ends are the same. Rack end length difference: 1.5 mm (0.059 in.) or less (e) Tighten the tie rod end lock nuts. Torque: 55 N m (560 kgf cm, 41 ft lbf) (f) Place the boots on the seats and install the clips. HINT: Make sure that the boots are not twisted. R13229 A B B A (g) Inspect the wheel angle. Turn the steering wheel fully and measure the turning angle. A: Inside B: Outside FA

If the right and left wheel turning angles differ from the specified values, readjust the toein and wheel angle to within the specified values. At this time, make sure that the lengths of the right and left rack ends are the same. Rack end length difference: 1.5 mm (0.059 in.) or less 3024
