Disassembly and Assembly
DISASSEMBLY
1. Prior to disassembling, measure pinion rotating torque.
- Before measuring, disconnect gear housing tube and drain fluid.
Within ± 100° from the neutral position:
Average rotating torque 0.78 - 1.47 Nm (8.0 - 15.0 kg-cm, 6.9 - 13.0 inch lbs.)
Maximum torque deviation 0.4 Nm (4 kg-cm, 3.5 inch lbs.)
Except for above measuring range:
Maximum rotating torque 2.1 Nm (21 kg-cm, 18 inch lbs.)
Maximum torque deviation 0.6 Nm (6 kg-cm, 5.2 inch lbs.)
- If pinion rotating torque is not within the specifications, replace steering gear assembly.
- Use soft jaws when holding steering gear housing. Handle gear housing carefully, as it is made of aluminum. Do not grip cylinder in a vise.
2. Remove tie-rod outer sockets and boots.
3. Loosen tie-rod inner socket by prying up staked portion, and removing socket.
INSPECTION
Thoroughly clean all parts with cleaning solvent or automatic transmission fluid type DEXRON III or equivalent. Blow dry with compressed air, if available.
Boot
Check condition of boot. If cracked excessively, replace it.
Tie-rod Outer And Inner Sockets
- Check outer and inner ball joints for swinging force "A" and axial end play "C."
Refer to image
- Check outer ball joint for rotating torque "B."
Refer to image
- Check condition of dust cover. If excessively cracked, replace outer tie-rod.
ASSEMBLY
1. Install new lock plate.
- Attach lock plate (2) to tie-rod inner socket (1).
- Apply locking sealant to inner socket threads (3). Screw inner socket into rack (4) and tighten to specified torque.
- Clinch two places of lock plate at tie-rod inner socket.
CAUTION: To prevent scratching the boot, remove burrs from lock plate.
2. Tighten outer socket lock nut.
Tie-rod standard length "L"
3. Measure rack stroke.
Rack stroke "S"
4. Before installing boot, coat the contact surfaces between boot and tie-rod with grease.
5. Install boot clamps.
- Install large boot clamp using suitable tool and crimp securely.
- Install small boot clamp as shown.
