GENERAL TOOL

GENERAL TOOL DESCRIPTION

PRECAUTIONS

1. Wear working clothing, including a cap, protective goggles and protective shoes during operation.
2. Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, installation, disassembly, and replacement.
3. Use genuine grease etc. or the equivalent. Do not mix grease etc. with that of another grade or from other manufacturers.
4. Before securing a part on a vise, place cushioning material such as wood blocks, aluminum plate, or shop cloth between the part and the vise.
5. Be sure to tighten fasteners including bolts and nuts to the specified torque.
6. Place shop jacks or rigid racks at the specified points.

WHEEL ARCH HEIGHT

Set the vehicle on a level surface.

Set the vehicle to "curb weight" conditions. (Empty luggage compartment, install spare tire, jack, service tools, and top up fuel tank.)

Set the steering wheel in a straight line, then remove the vehicle straight ahead more than 5 m (16 ft) to settle the suspension.

Suspend the thread from wheel arch (point "A" in figure below) to determine a point directly above center of wheel.

Measure the distance between measuring point "A" and center of wheel.

Scheme 52

REAR BUSHING

Scribe an aligning mark on the transverse link and rear bushing.

Loosen the nut, and then remove the rear bushing.

Scheme 53

Assemble in the reverse order of disassembly.

Scheme 54

1. Face bushing toward center of ball joint
2. Ball joint
3. +/-3°

Install the rear bushing to transverse link, and then align the aligning marks scribed on the two.

Tighten the new self-locking nut.

Note. While holding the rear bushing so as not to change position of aligning marks, tighten the self-locking nut.

Tightening torque

190 Nm (19.4 kgf-m, 140 ft-lb)

DAMPER STRUT

Check for oil leakage.

Move the piston rod up and down to check that it operates smoothly without any binding.

Play of piston rod

1. Measure the play as follows

Fix outer shell and fully extend the rod. Set a dial gauge at the end of rod: L [10 mm (0.39 in)], then apply a force of W [20 N (2 kgf, 4 lb)] to threaded portion. With the force of 20 N (2 kgf, 4 lb) applied, read dial gauge indication: P 1 . Apply a force of 20 N (2 kgf, 4 lb) in the opposite direction of "W", then read dial gauge indication: P 2 .

Scheme 55

Limit of play (P 1 + P 2 )

0.8 mm (0.031 in)

If the play is greater than limit, replace the strut.

STRUT MOUNT

Check the rubber part for creep, cracks and deterioration, and replace it with a new one if defective.

DUST COVER

If any cracks or damage are found, replace it with a new one.

COIL SPRING

One having permanent strain should be replaced with a new one. When the vehicle posture is uneven, although there are no considerable reasons like tire puncture, uneven loading, etc., check the coil spring for its free length referring to specifications, cracks, etc., and replace it with a new one if defective.

HELPER

Replace it with a new one if cracked or damaged.

DISPOSAL

Place the gas filled strut on a flat and level surface with piston rod fully extended.

Using a 2 to 3 mm (0.08 to 0.12 in) dia. drill, make holes in areas shown in the figure.

Scheme 56

1. 10 mm (1.57 in)
