WARNING:
When hoisting vehicle, be sure to select the lifting point suitable for the service work referring to Sec-
tion 0A.
NOTE:
All front suspension fasteners are an important attaching part in that it could affect the performance
of vital parts and systems, and/or could result in major repair expense. They must be replaced with
one of the same part number or with an equivalent part if replacement becomes necessary. Do not
use a replacement part of lesser quality or substitute design. Torque values must be used as speci-
fied during reassembly to assure proper retention of this part.
Never attempt to heat, quench or straighten any front suspension part. Replace it with a new part or
damage to the part may result.

Wheel Disc, Nut and Bearing Check
1) Inspect each wheel disc for dents, distortion and cracks.
Disc in badly damaged condition must be replaced.
2) Check wheel nuts for tightness and as necessary, retighten
them to specification.
Tightening torque
Wheel nuts

3) Check wheel bearing for wear. After retightening lock nut to
specified torque, apply dial gauge to wheel hub center and
measure thrust play.
Wheel bearing thrust play limit
: 0.05 mm (0.002 in)
When measurement exceeds limit, replace bearing.
4) By rotating wheel actually, check wheel bearing for noise and
smooth rotation. If defective, replace bearing.
