Disassembly

Caution: Do not allow absorber rod to rotate during disassembly/assembly. Use hand tools to keep absorber rod from rotating. If air tools are used, and rod is allowed to rotate, damage to absorber may occur.

Caution: Do not handle top mount assembly by plastic portion. Handle top mount assembly by metal portion when removing/installing top mount from/to strut assembly. Holding top mount assembly by plastic portion may loosen snap fit of bearing components and cause bearing to fall apart.

Before removing any of front strut assembly components, note alignment and orientation of all components to aid in installation.

Ensure front suspension strut assembly is vertical in spring compressor.

Use proper size socket to hold front suspension strut shaft while loosening front suspension strut shaft nut.

If any of front suspension strut assembly components show signs of excessive wear or are damaged, replace those components.

If front spring does not have to be serviced, leave spring in spring compressor.

1.	Remove strut assembly.

2.	Remove front suspension strut shaft nut cover (1), if equipped, Fig. 1.

3.	Position front suspension strut assembly in compressor tool No. CH-45400, or equivalent and adjust upper and lower legs so that they are properly positioned on front spring, Fig. 2.

4.	Hand ratchet and proper socket (1) to loosen front suspension strut shaft nut, using socket tool No. J-42991, or equivalent (2), Fig. 3.

5.	Remove front suspension strut shaft nut (1), Fig. 4.

Remove front suspension strut mount (8), front suspension strut mount bearing (7), front spring upper insulator (6), front spring (5) (if required), front suspension strut dust shield (4), front suspension strut bumper (3), front spring lower insulator (2) and front suspension strut (1), Fig. 5.

Assembly

Ensure that front suspension strut assembly is vertical in spring compressor.

1.	If removed, position front spring in compressor tool No. CH-45400, or equivalent and adjust upper and lower legs so that they are properly positioned on front spring.

2.	Compress front spring enough to install remaining front suspension strut assembly components, using compressor tool No. CH-45400, or equivalent.

3.	Install front spring lower insulator, front suspension strut bumper and front suspension strut dust shield on front suspension strut.

4.	Position front suspension strut with assembled components in compressor tool No. CH-45400, or equivalent.

5.	Install front spring upper insulator, front suspension strut mount bearing and front suspension strut mount on front suspension strut.

6.	Inspect to ensure that tab on front spring upper insulator is aligned with tab on front spring lower insulator and center of front suspension strut.

7.	Flat on front suspension strut mount should be aligned with tab on front spring upper insulator.

8.	Ensure front spring is properly seated on front spring lower insulator.

9.	Install front suspension strut shaft nut.

10.	Torque front suspension strut shaft nut to 63 ft. lbs., using socket tool No. J-42991, or equivalent, torque wrench and proper socket.

11.	Remove front suspension strut assembly from compressor tool No. CH-45400, or equivalent.

12.	Install front suspension strut shaft nut cover, if equipped.

13.	Install strut assembly.
