1. Ensure vehicle is unladen condition*.* Fuel, radiator coolant and engine oil full. Spare tire, jack,hand tools and mats in designated positions.
2. Have a driver sit in the driver's seat and one person sit on the rear end. Then have the person on the rear end slowly get off
the vehicle. This is necessary to stabilize suspension de¯ec-
tion.
3. Gradually depress brake pedal and attach a lever to the stop- per bolt, then adjust length ``L'' as follows:Length ``L'': Approx. 175.2 - 178.2 mm (6.90 - 7.02 in)
4. Remove front LH tire.
5. Connect tool to air bleeders on front LH brake caliper and rear LH or RH brake wheel cylinder.
6. Install front LH tire.
Before installing front LH tire, con®rm the tool is not touching
the front LH wheel.
7. Bleed air from Tool.
8. Raise front brake pressure to 4,904 kPa (49.0 bar, 50 kg/cm
2,
711 psi) and 9,807 kPa (98.1 bar, 100 kg/cm2, 1,422 psi) and
check rear brake pressure. Rear brake pressure: Refer to table on next page.

REMOVAL AND INSTALLATION
1. Support front axle case with jack.
2. Remove both upper and lower sides ®xing nuts.
INSPECTION
Except for nonmetallic parts, clean all parts with suitable solvent
and dry with compressed air.
Use compressed air to blow dirt and dust off of nonmetallic parts.
+Check for oil leakage and cracks. Replace if necessary.
+Check piston rod for cracks, deformation and other damage.
Replace if necessary.
+Check rubber parts for wear, cracks, damage and deformation.
Replace if necessary.
Stabilizer Bar
REMOVAL
+Remove stabilizer bar connecting bolts and clamp bolts.
INSPECTION
+Check stabilizer bar for twist and deformation.
Replace if necessary.
+Check rubber bushing for cracks, wear and deterioration.
Replace if necessary.
INSTALLATION
+Install stabilizer bar with ball joint socket properly placed.
Coil Spring
INSPECTION
Visually check for cracks or damage. If faulty, replace.
Ensure that springs are installed correctly. Incorrect installa-
tion will cause vehicle not set in horizontal posture.
