Scheme 52

1. Remove the front wheel & tire. Tightening torque: 88.3 ~ 107.9N.m(9.0 ~ 11.0kgf.m, 65.1 ~ 79.6lb-ft) CAUTION: Be careful not to damage to the hub bolts when removing the front wheel & tire.
2. Remove the wheel speed sensor (B) from the front strut assembly by loosening mounting bolts (A).
3. Disconnect the stabilizer link (B) from the front strut assembly (A) after loosening the nut. Tightening torque: 98.1 ~ 117.7N.m(10.0 ~ 12.0kgf.m, 72.3~86.8lb-ft)
4. Disconnect the front strut assembly (A) from the knuckle by loosening the bolt & nut. Tightening torque: 156.9 ~ 176.5N.m (16.0 ~ 18.0kgf.m, 115.7 ~ 130.2lb-ft)
5. Remove the front strut assembly and then loosen the strut mounting nuts (A). Tightening torque: 53.9 ~ 73.5N.m(5.5 ~ 7.5kgf.m, 39.8 ~ 54.2lb-ft)
6. Installation is the reverse of removal.

Scheme 53

1. Using the special tool (09546-26000), compress the coil spring (A). Tightening torque: 58.8 ~ 68.6N.m(6.0 ~ 7.0kgf.m, 43.4 ~ 50.6lb-ft)
2. Remove the self-locking nut (C) from the strut assembly (B).
3. Remove the insulator, spring seat, coil spring and dust cover from the strut assembly.
4. Reassembly is the reverse of the disassembly.

Scheme 54

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.
