General Procedures
Front Axle and Rear Axle Precautions
Wheel and Tire Removal/Installation
1. This section does not describe wheel and
tire removal and installation steps; if the
wheels are removed, the installation
tightening torque will be 88-127 N.m
{9.0-13.0 kgf.m, 65-94 ft.lbf}.
Brake Line Removal and Connection
Attention:
Brake fluid may damage paint surfaces. Hence,
if brake fluid stains paint surface, immediately
erase it.
1. Use SST (49 0259 770B) to tighten the
brake line flared nut. If the torque wrench
and the SST are used in combination, be
sure to adjust the brake line flared nut
tightening torque (for use of SST
combined kit, see GI torque formula).
2. If brake line is disconnected during the
process, add brake fluid and drain air in
brake system. After completing the above
steps, check for leaks.
Rear Bracket arm Removal/Installation
1. Only when vehicle body height is
lowered and in no-load conditions can all
suspension parts with the rubber bushing
be tightened.
Notes: No load – Fuel tank in the state of
fully filled; engine coolant and
lubricating oil maintain required fluid
levels. Spare tire, jack and tool kit are in
the designed position.
Front Axle
Hub, Steering Knuckle Pre-inspection
Wheel Bearing Clearance Inspection
1. Attach dial gauge relatively fixed to the
wheel.
2. Pull and push the hub along the axial
direction by hand and measure wheel
bearing clearance.
Wheel bearing max. clearance: 0.05 mm
{0.002 in}
3. If the bearing clearance exceeds the
specified value, replace the locknut and in
accordance with the specified torque,
tighten it before re-testing. If necessary,
replace the wheel bearing.
Hub Bolt Replacement
1. Use SST to remove hub bolt.
Notes: If the mudguard prevents wheel
hub bolt removal, use a chisel to lightly
tap the part shown in the diagram to bend
it to the side of the steering knuckle.
2. Install wheel hub bolt into the wheel hub
and install gasket and hub nut.
3. Use a copper rod to fix the wheel hub and
tighten the wheel hub nut.
