Paint Mark

NOTICE:

The paint mark of the rear coil spring LH should be towards the underside and rear side of the vehicle.

Support the rear axle beam with a jack. Insert a wooden block between the jack and the rear axle spring seat to prevent damage.

Jack up the rear axle beam slowly, and provisionally install the rear shock absorber assembly (lower side) with the bolt and nut onto the rear axle beam assembly.

Install the suspension rear support and rear shock absorber cushion retainer.

While holding the piston rod, install a new nut (lower nut) to the specified standard.

Standard:

15 to 18 mm (0.591 to 0.709 in.)

Install a new nut (upper nut) onto the lower nut.

Hold the lower nut and tighten the upper nut against it.

Torque:

25 N*m{250 kgf*cm, 18 ft.*lbf}

Install the axle hub and bearing onto the axle beam with the 4 bolts.

Torque:

90 N*m{918 kgf*cm, 66 ft.*lbf}

Install the dust cover and the axle hub and bearing onto the axle beam with the 4 bolts.

Torque:

90 N*m{918 kgf*cm, 66 ft.*lbf}

Using a dial indicator, check the backlash near the center of the axle hub.

Maximum:

0.05 mm (0.00197 in.)

Using a dial indicator, check the backlash near the center of the axle hub.

Maximum:

0.05 mm (0.00197 in.)

Using a dial indicator, check the runout of the surface of the axle hub.

Maximum:

0.07 mm (0.00276 in.)

Using a dial indicator, check the runout of the surface of the axle hub.

Maximum:

0.07 mm (0.00276 in.)

Align the matchmarks of the rear disc and axle hub and install the rear disc.

NOTICE:

When replacing the disc with a new one, select the installation position where the rear disc has minimal runout.

Install the rear disc brake cylinder mounting to the axle beam with the 2 bolts.

Torque:

57 N*m{585 kgf*cm, 42 ft.*lbf}

Install the 2 rear disc brake pads to the rear disc brake cylinder mounting.

NOTICE:

There should be no oil or grease on the friction surfaces of the disc brake pads or the rear disc.

To compensate for pad wear when reusing the pad, use SST to push and turn the piston (LH side: counterclockwise, RH side: clockwise) to the position where the protrusion on the pad lines up properly with the piston groove.
