Spare tire, jack, handtools and mats in designated positions.SFA975BPreliminary InspectionNGSU0007S01Aluminum WheelNGSU0007S01011. Check tires for wear and proper inflation.2. Check wheels for deformation, cracks and other damage.If deformed, remove wheel and check wheel runout.1) Remove tire from aluminum wheel and mount wheel on a tirebalance machine.2) Set dial indicator as shown in the illustration.Wheel runout (Dial indicator value):Refer to SDS, SU-19.3. Check front wheel bearings for looseness.4. Check front suspension for looseness.5. Check steering linkage for looseness.6. Check that front shock absorbers work properly by using thestandard bounce test.GIMAEMLCECFECLMTATTFPDAXBRSTRSBTHASCELIDXFRONT SUSPENSIONOn-vehicle ServiceSU-7 ASU039Steel WheelNGSU0007S01021. Check tires for wear and proper inflation.2. Check wheels for deformation, cracks and other damage.If deformed, remove wheel and check wheel runout.1) Remove tire from steel wheel and mount wheel on a tire bal-ance machine.2) Set two dial indicator as shown in the illustrations.3) Set each dial indicator to 0.4) Rotate wheel, and check dial indicators at several pointsaround the circumference of the wheel.5) Calculate runout at each point as shown below.Radial runout = (A+B)/2Lateral runout = (C+D)/26) Select maximum positive runout value and the maximumnegative value.Add the two values to determine total runout.In case a positive or negative value is not available, use themaximum value (negative or positive) for total runout.If the total runout value exceeds the limit, replace steel wheel.Radial runout limit: 0.5 mm (0.020 in)Lateral runout limit: 0.8 mm (0.031 in)3. Check front wheel bearings for looseness.4. Check front suspension for looseness.5. Check steering linkage for looseness.6. Check that front shock absorbers work properly by using thestandard bounce test.ASU0191. Check vehicle posture (Unladen): H = A − B mm (in)Refer to SDS, SU-20.a. Exercise the front suspension by bouncing the front of thevehicle 4 or 5 times to ensure that the vehicle is in a neutralheight attitude.b. Measure wheel alignment.Refer to SDS, SU-20.c. If wheel alignment is not as specified, adjust vehicle posture.Refer to SDS, SU-20.d. Adjust wheel alignment.Refer to SDS, SU-20.FRONT SUSPENSIONOn-vehicle Service (Cont’d)SU-8 SFA894Camber, Caster and Kingpin InclinationNGSU0007S02Before checking camber, caster or kingpin inclination, movevehicle up and down on turning radius gauge to minimizefriction. Ensure that the vehicle is in correct posture.¼ Measure camber, caster and kingpin inclination of both rightand left wheels with a suitable alignment gauge and adjust inaccordance with the following procedures.Camber, Caster and Kingpin inclination:Refer to SDS, SU-20.SFA817B¼ In the following two cases, temporarily tighten the adjustingbolts while aligning the matching marks with the slits as shownin the figure at the left and measure the camber, caster andkingpin inclination:a) When replacing the upper link or other suspension parts withnew onesb) When matching marks were not painted on adjusting boltsbefore suspension disassembly procedures¼ If matching marks were already painted during suspensiondisassembly, align the matching marks with the slits, then tem-porarily tighten the adjusting bolts. Measure the camber, casterand kingpin inclination.SFA817BAdjustmentNGSU0007S031. Both camber and caster angles are adjusted by adjusting bolts.¼ If the kingpin inclination is outside specifications, check thefront suspension parts for wear or damage. Replace faultyparts with new ones.2. From the measured value, read the coordinate (or: graduation)at the intersecting point in the graph.a. If the coordinate (or: graduation) at the intersecting point ispositive, move the pin outward by turning the correspondingadjusting bolt by the indicated graduation.b. If the coordinate (or: graduation) at the intersecting point isnegative, move the pin inward by turning the correspondingadjusting bolt by the indicated graduation.After properly moving the pin(s), tighten the front and rearadjusting bolts to specifications.3. Re-measure to ensure that the camber and caster are withinspecified tolerances.[Example]a. Measured values corresponding with the two values indicatedbelow: (See chart for 4WD model.)Camber angle: −0°06′ (−0.10°)Caster angle: 2°10′ (2.17°)GIMAEMLCECFECLMTATTFPDAXBRSTRSBTHASCELIDXFRONT SUSPENSIONOn-vehicle Service (Cont’d)SU-9 b. Apply the above two values to the graph and determine point“A”.c. The coordinate (or: graduation) indicates that both the frontand rear adjusting bolts must be turned outward by 3 gradua-tions.Turn the adjusting bolts by the amount corresponding with the3 graduations.AFA147SFA614BSFA234ACToe-inNGSU0007S04Measure toe-in using the following procedure.WARNING:¼ Always perform the following procedure on a flat surface.¼ Make sure that no one is in front of the vehicle beforepushing it.1. Bounce front of vehicle up and down to stabilize the posture.2. Push the vehicle straight ahead about 5 m (16 ft).3. Put a mark on base line of the tread (rear side) of both tires atthe same height of hub center. This mark is a measuring point.4. Measure distance “A” (rear side).5. Push the vehicle slowly ahead to rotate the wheels 180degrees (1/2 turn).¼ If the wheels have rotated more than 180 degrees (1/2turn), try the above procedure again from the beginning.Never push vehicle backward.6.
