Replacement

1. | Remove the front wheel & tire.

Tightening torque:
88.3 ~ 107.9 N.m (9.0 ~ 11.0 kgf.m, 65.1 ~ 79.6 lb-ft)

Be careful not to damage to the hub bolts when removing the front wheel & tire.

2. | Remove the brake hose (A) & wheel speed sensor bracket (B) from the front strut assembly by loosening mounting bolts.

3. | Disconnect the stabilizer link (B) with the front strut assembly (A) after loosening the nut.

Tightening torque:
98.1 ~ 117.7 N.m (10.0 ~ 12.0 kgf.m, 72.3 ~ 86.8 lb-ft)

4. | Disconnect the front strut assembly (A) with the knuckle by loosening the bolt & nut.

Tightening torque:
137.3~156.9 N.m (14.0~16.0 kgf.m, 101.3~115.7 lb-ft)

5. | Remove the front strut assembly and then loosen the strut mounting nuts (A).

Tightening torque:
44.1 ~ 58.8 N.m (4.5 ~ 6.0 kgf.m, 32.5 ~ 43.4 lb-ft)

6. | Installation is the reverse of removal.

Disassembly

1. | Compress the coil spring with a SST(09546-26000). Do not compress the spring more than necessary.

2. | Loosen the self locking nuts (A).

3. | Remove the insulator assembly (A) and the strut bearing (B).

4. | Remove the spring upper seat (A) and pad (B).

5. | Remove the dust cover (A) and the bumper rubber (B).

6. | Remove the coil spring (A) and the spring lower pad (B).

7. | Remove the shock absorber (A) from the specialtool.

8. | Reassembly is the reverse of the disassembly.

Inspection

1. | Check the strut bearing for wear and damage.

2. | Check the spring upper and lower seat for damage and deterioration.

3. | Compress and extend the piston rod (A) and check that there is no abnormal resistance or unusual sound during operation.
