PM-30 Suspension PERIODIC MAINTENANCE SERVICES 3. WHEEL ARCH HEIGHT 1) Unload the vehicle, so that it is at curb weight. 2) Check the wheel arch height of the front and rear suspensions to ensure that they are within toler- ance. <Ref. to FS-8, Wheel Alignment.> 3) If the wheel arch height is out of the specifica- tion, visually check the following components and replace deformed parts. • Suspension components [Front strut assembly and rear shock absorber assembly] • Parts connecting suspension and body 4) When no components are deformed, adjust the wheel arch height by replacing the suspension for which the wheel arch height is not within tolerance. <Ref. to FS-8, Wheel Alignment.> 4. WHEEL ALIGNMENT OF FRONT SUS- PENSION 1) Check the alignment of front suspension to make sure the following items are within tolerance. • Toe-in • Camber • Caster (referential value) • Steering angle <Ref. to FS-8, Wheel Alignment.> 2) When the caster angle does not conform to the reference value obviously, visually inspect the fol- lowing components and replace deformed parts. • Suspension components [Strut assembly, cross- member, front arm, etc.] • Parts connecting suspension and body 3) When the toe-in and camber are outside of the tolerance value, adjust each one so that they con- form to the tolerance value. 4) When the rotating angles of the right and left tires are not within tolerance, adjust them to stan- dard. <Ref. to FS-8, Wheel Alignment.> 5. WHEEL ALIGNMENT OF REAR SUS- PENSION 1) Inspect the alignment of the rear suspension and check the following items are within the specified range. • Toe-in • Camber • Thrust angle <Ref. to RS-8, Wheel Alignment.> 2) If camber is out of the specification, visually check the items listed below. If the deformation is found, replace the damaged part. • Suspension component [shock absorber, front lateral link, rear lateral link, upper arm, trailing link, sub frame etc.] • Parts connecting suspension and body 3) If the toe-in or thrust angle is out of the tolerance, adjust to the tolerance value. <Ref. to FS-8, Wheel 6. OIL LEAKAGE OF STRUT AND SHOCK ABSORBER Visually inspect the front strut and rear shock ab- sorber for oil leakage. Replace the front strut and rear shock absorber if oil leaks excessively. 7. TIGHTNESS OF BOLTS AND NUTS Check the bolts and nuts for looseness. Retighten the bolts and nuts to specified torque. If the self- locking nuts and bolts are removed, replace them with new parts. Front suspension: <Ref. to FS-2, General Descrip- Rear suspension: <Ref. to RS-2, General Descrip- 8. DAMAGE TO SUSPENSION PARTS Check the following parts and the fastening portion of the vehicle body for deformation or excessive rusting which impairs the suspension. If necessary, replace the damaged parts with new parts. If minor rust formation, pitting, etc. are noted, remove the rust and take rust prevention measure. • Front suspension • Front arm • Rear suspension • Sub frame • Front lateral link • Trailing link • In the area where salt is sprayed to melt snow on a road in winter, check suspension parts for dam- age caused by rust every 12 months after lapse of 60 months. Take rust prevention measures as re- quired. gi14usena07.fm 30 ページ ２０１３年９月１０日 火曜日 午後３時５９分 |
