INSPECTION AFTER ASSEMBLY

When the steering wheel does not turn smoothly, check as follows:
1. Check the steering column for the following:

• Damage to the column tube or bearings

• Wear around the seal edges

• Corrosion or pitting around the seal sliding area

Replace the steering column as an assembly, if necessary.

CAUTION:

• Do not exert any axial load or impact to the steering column.

• Replace the column if it is depleted of grease, worn, damaged, or if any scratches or coating

separation is present on the shaft seal area.

2. If the vehicle has been in a collision, or if noises are heard com-

ing from the steering column, check column length (L) as shown.

If out of specification, replace the steering column as an assem-

bly.

3. Check the tilt device for proper operation range.

POWER STEERING OIL PUMP

INSPECTION BEFORE DISASSEMBLY

Disassemble the power steering oil pump only if the following items are found.

• Deformed or damaged pulley, bracket, connector or suction pipe

• Oil leakage from the suction pipe or connector. 

DISASSEMBLY

NOTE:

Mount the power steering oil pump in a vise as needed.
1. Remove the connector bolt, connector and copper sealing washers.

CAUTION:

Do not reuse the copper sealing washers.

2. Remove the suction pipe and O-ring.

CAUTION:

Do not reuse the O-ring.

3. Remove the pulley nut and pulley.
4. Remove the bracket bolts and bracket(s).

INSPECTION AFTER DISASSEMBLY

Body Assembly Inspection

Check the power steering oil pump body assembly for damage. If any damage is found, replace with a new

power steering oil pump assembly.

ASSEMBLY

CAUTION:

• Secure the gear housing assembly with a vise. Use copper plates or equivalent to prevent it from

being damaged. Do not grip the cylinder with a vise.

• Before performing disassembly, clean the gear housing assembly. Be careful not to allow any

cleaner to contact the discharge and return port connectors.

DISASSEMBLY

1. Remove the cylinder tubes from the gear housing assembly.
2. Loosen the lock nuts of the outer sockets, then remove the outer sockets from the inner sockets.
3. Remove the boot clamps from the boots, then remove the boots from the inner sockets and gear housing

assembly.

CAUTION:

• Do not reuse the large-diameter boot clamps.

• Do not damage the boots, inner socket or gear housing assembly. If they are damaged, replace

them.

4. Remove the inner sockets.

STEERING GEAR AND LINKAGE

Gear Housing Assembly

Check gear housing assembly for dents, cracks or damage. Replace as an assembly if necessary.

Outer Socket and Inner Socket

SWING TORQUE

• Measure the swing torque, using Tool. When ball stud and inner

socket start moving the measured value must be within the specifi-

cation. If the reading is outside the specification, replace the

socket. Refer to 

ST-36, "Steering Gear"

.

ROTATING TORQUE

• Measure the rotating torque, using Tool. If the value is outside the

specification, replace the outer sockets.

AXIAL END PLAY

• Apply a load of 490 N (50 kg, 110 lb) to the ball stud axially. Use a

dial gauge to measure the amount of the movement that the stud

makes. If the value is outside the specification, replace the sock-

ets.

ASSEMBLY

1. Install the inner sockets.
