- Remove the wheel speed sensor bracket bolt (A).
Tightening torque: 8.8 - 13.7 N*m (0.9 - 1.4 kgf*m, 6.5 - 10.1 lb*ft)
- Remove the caliper hose bracket bolt (A).
Tightening torque: 8.8 - 13.7 N*m (0.9 - 1.4 kgf*m, 6.5 - 10.1 lb*ft)
- Loosen the front strut lower bolts.
Tightening torque: 156.9 - 176.5 N*m (16.0 - 18.0 kgf*m, 115.7 - 130.2 Ib*ft)
- Remove the cowl top cover.
(Refer to Body - "Cowl Top Cover")
- Loosen the front strut upper nuts and then remove the strut assembly.
Tightening torque: 53.9 - 73.5 N*m (5.5 - 7.5 kgf*m, 39.8 - 54.2 Ib*ft)
Disassembly
- Using a strut spring compressor, compress the coil spring.
Warning
- To prevent peeling the paint of coil spring, cover the coil spring with a thin cloth or hose before installing strut spring compressor.
- Set the compression position of strut spring compressor correctly for coil spring not to slant when compressing the coil spring.
- Remove the insulator cap (A).
- Loosen the insulator nut (A) and then remove the insulator.
Tightening torque: 78.5 - 88.2 N*m (8.0 - 9.0 kgf*m, 57.9 - 65.0 lb*ft)
- Remove the strut bearing, spring upper pad and ruber.
- Remove the spring (A) and dust cover (B).
- Remove the spring lower pad (A).
Inspection
- Check the strut insulator for wear or damage.
- Check rubber parts for damage or deterioration.
- Compress and extend the piston rod (A) and check that there is no abnormal resistance or unusual sound during operation.
Disposal
- Fully extend the piston rod.
- Drill a hole on the A section to remove gas from the cylinder.
Reassembly
- Install the spring lower pad (D) so that the protrusions (A) fits in the holes (C) in the spring lower seat (B).
- Compress coil spring using a strut spring compressor. Install compressed coil spring (A) into shock absorber.
Notice
- Identification color marks are indicated on the coil spring. Pay attention to identification mark during installation.
- Install the coil spring with the identification mark directed toward the knuckle.
- After fully extending the piston rod, install the spring upper seat and insulator assembly.
- After seating the upper and lower ends of the coil spring (A) in the upper and lower spring seat grooves (B) correctly, tighten new self-locking nut temporarily
- Remove the special tool (09546-26000).
- Tighten the self-locking nut to the specified torque.
Tightening torque : 58.8 - 68.6 N*m (6.0 - 7.0 kgf*m, 43.4 - 50.6 lb*ft)
