Manual Description
Upper Ball Joint Lower Ball Joint20, when installing rubber parts, final tightening must be carried out under unladen condition* with tires ground, *: Fuel, radiator coolant and engine oil full, hand tools and mats designated positions.
Use flare nut wrench when removing installing brake, after installing removed suspension parts, check wheel, always torque brake lines when installing, the actual shapes of Kent-Moore tools may differ from those of special service tools illustrated here.
Removing ball joint knuckle spindle, removing and installing lower link bushing, removing and installing each brake piping, noise, Vibration Harshness (NVH) Troubleshooting.
Use the chart below to help you find the cause of the symptom, check front suspension parts for excessive play, cracks, wear, ¼ Shake each front wheel to check excessive play, if looseness is noted, adjust wheel bearing end play, then.
¼ Make sure that the cotter pin inserted, ¼ Retighten all nuts and bolts to the specified torque, mODEL”, SU-4; 2WD VG33E, VG33ER, ¼ Check shock absorber for oil leakage other damage.
¼ Check suspension ball joint for grease leakage ball joint, dust cover for cracks other damage, before checking front wheel alignment, make preliminary inspection (Unladen*), tools and mats designated positions.
Check tires for wear proper inflation, check wheels for deformation, cracks other damage, if deformed, remove wheel check wheel runout, refer to WHEEL RUNOUT AVERAGE”, SU-20.
Check front wheel bearings looseness, check that front shock absorbers work properly by using, check vehicle posture (Unladen): H = A − B mm (in), refer to KA24DE Model”, SU-21, 2WD VG33E.
And Models”, SU-22, 4WD Model”, SU-22, exercise the front suspension by bouncing front, vehicle or 5 times to ensure that the vehicle neutral, if wheel alignment is not as specified, adjust vehicle posture.
Before checking camber, caster kingpin inclination, move, vehicle up and down on turning radius gauge minimize, ¼ Measure camber, caster and kingpin inclination both right, and left wheels with a suitable alignment gauge adjust.
And Models”, SU-22, 4WD Model”, in the following two cases, temporarily tighten adjusting, bolts while aligning the matching marks with slits shown, when replacing the upper link or other suspension parts with.
When matching marks were not painted adjusting bolts, if matching marks were already painted during suspension, disassembly, align the matching marks with the slits, then temporarily tighten the adjusting bolts, both camber and caster angles are adjusted by adjusting bolts.
If the kingpin inclination is outside specifications, check, front suspension parts for wear damage, from the measured value, read coordinate (or: graduation), at the intersecting point graph.
If the coordinate (or: graduation) at intersecting point, positive, move the pin outward by turning corresponding, adjusting bolt by indicated graduation.
