REAR SUSPENSION FASTENERS
Check each bolt and nut fastening suspension parts for tightness.
Tighten loose one, if any, to specified torque, referring to ªTIGHT-
ENING TORQUE SPECIFICATIONSº of this section.
BEARING RETAINER AND AXLE SHAFT
INNER OIL SEAL CHECK
When brake drum has been removed, check inside of brake drum
for gear oil leakage.
Also, check backside of brake back plate for oil leakage.
If oil leakage is found, replace defective oil seal.
Whenever it is possible to check oil seal during disassembly,
check its lip for wear.
If oil leakage or worn lip is found, replace defective oil seal.
WHEEL DISC, NUT & BEARING CHECK
Inspect each wheel disc for dents, distortion and cracks. A disc
in badly damaged condition must be replaced.
Check wheel hub nuts for tightness and retighten to specification
as necessary.
Tightening Torque
(a): 100 N
.m (10.0 kg-m, 72.5 lb-ft)
Check wheel bearings for wear. When measuring thrust play, ap-
ply a dial gauge to axle shaft center after removing wheel center
cap from wheel.
Thrust play limit
Rear0.8 mm (0.03 in.)
When measurement exceeds limit, replace bearing.
By rotating wheel actually, check wheel bearing for noise and
smooth rotation. If it is defective, replace bearing.
