16. Remove steering column cover.
17. Disconnect the wiring harness connectors located under the steering column.
18. Remove the combination switch assembly with SRS coil.
NOTE: The SRS coil is a part of the combination switch
assembly, which cannot be replaced separately.
Therefore, be sure not to remove the SRS coil from the
combination switch assembly.

19. Disconnect the starter switch harness connector
located under the steering column, then remove
lock cylinder assembly.

20.
Apply a setting mark (1) across the universal joint
and steering shaft to reassemble the parts in thei
r
original position, then remove steering column
assembly and second shaft.
NOTE: A setting mark can be easily made if the shaft is
withdrawn a little by loosening the steering shaft
universal joint.

Inspection
If abnormal conditions are found during inspection,
replace the steering column assembly.

Column Capsules
Check capsules on steering column bracket assembly;
all must be securely seated in bracket slots and
checked for any loose condition when pushed or pulled
by hand.

Check clearance between capsule and bracket. It must
be less than 1 mm (0.039 in).

Column Universal Joint (between the
power steering unit and the steering shaft)
If resistance is felt when checked by rotating the joint,
replace the lower second steering shaft.

Shaft Universal Joint (between the lower
second steering shaft and the second
steering shaft)
If resistance is felt when checked by rotating the joint,
replace the second steering shaft assembly.

Tilt Mechanism
The tilt mechanism should move smoothly.
W hile locking the tilt mechanism, be sure the steering
column is latched securely by pushing the steering
wheel upward and downward.

Installation
1. Align the setting mark (1) on the second steering
shaft and the steering column assembly (applied at
disassembly).
2. Connect the steering column assembly to the second steering shaft. Tighten the bolts to the specified
torque.

3E-10 WHEELS AND TIRES
TROUBLESHOOTING
Typical examples of abnormal tire tread wear and major causes :

CAUTION:
Similar wear patterns can be caused by worn suspension parts, misalignment of wheels and tires, and
other suspension related problems.


Spotty wear - wear localized
on shoulder section. In
extreme cases, the tire
becomes polygonal in shape.
Tire or wheel out of
round or distorted. Hub or knuckle out
of round or distorted. Play in hub bearings
or ball joints. Rotating parts out of
balance.
Tread wear one-sided.
Rotating parts out of
balance. Tire or wheel out of
round. Hub or knuckle out
of round or distorted.
Localized tread wear.
Once spotty wear develops in
tread due to hard braking or
abrupt starting, localized wear
tends to be accelerated.

Note :
1. It is very important that the liquid gaskets listed above or their exact equivalent be used on the
vehicle.
2. Be careful to use the specified amount of liquid gasket.
Follow the manufacture's instructions at all times.

3. Be absolutely sure to remove all lubricants and
moisture from the connecting surfaces before
applying the liquid gasket.
The connecting surfaces must be perfectly dry.
4. LOCTITE 515 and LOCTITE 518 harden upon contact with a metal surface.
Do not apply LOCTITE 515 or LOCTITE 518 between two metal surfaces having a clearance
of greater than 0.25 mm (0.01 in). Poo
