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.
