INSTALLATION

CAUTION / NOTICE / HINT

HINT:

Use the same procedure for the RH side and LH side.
The following procedure is for the LH side.

PROCEDURE

1. INSTALL FRONT LOWER COIL SPRING INSULATOR

(a) Install the front lower coil spring insulator to the front shock absorber assembly.

Positioning Pin

NOTICE:

When installing the front lower coil spring insulator, insert the positioning pin of the spring seat into the hole of the front lower coil spring insulator.

2. INSTALL FRONT SPRING BUMPER

(a) Install the front spring bumper to the front shock absorber assembly as shown in the illustration.

Install in this direction

NOTICE:

Face the smaller diameter end of the front spring bumper downward.
Do not apply lubricants to the front spring bumper.
Do not apply lubricants to the front shock absorber assembly cap or rod.
Do not clean the front spring bumper with water or solvent.

3. INSTALL FRONT COIL SPRING

(a) Secure SST in a vise.

SST: 09727-00051

SST: 09727-30022

09727-00010

09727-00031

(b) Attach the hooks of each SST arm across the diameter of the coil spring.

CAUTION:

Make sure that the hooks are securely attached to the coil spring.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.
Make sure that the hooks of the upper and lower SST arms are attached to the coil spring so that the distance between the hooks is as large as possible.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.
Make sure that the arms of SST are parallel and the number of coils between the arms is the same on each side.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.

CAUTION:

Make sure that the stopper pins are installed securely.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.

(d) Using SST, compress the coil spring.

CAUTION:

If the coil spring starts to bow out while using SST, stop immediately and reattach SST correctly.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.
Do not compress the coil spring to the point where the coils touch each other.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.
Do not use an impact wrench.
If an impact wrench is used, the threads of SST may be damaged, or sudden compression of the coil spring may cause a hook to disengage and the coil spring to fly out, resulting in injury.
If a stopper pin touches the coil spring while using SST, remove the stopper pin and continue with the procedure.
If a stopper pin is removed, install a coil spring stopper belt as shown in the illustration.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.

SST: 09727-00110

(e) Align the end of the front coil spring with the flange of the front lower coil spring insulator and install the front coil spring.

NOTICE:

Make sure to fit the end of the front coil spring that has the larger diameter into the depression of the front lower coil spring insulator.

*a	Top End of the Insulator (Shock Absorber Dust Cover)

5. INSTALL FRONT SUSPENSION SUPPORT SUB-ASSEMBLY

(a) Install the front suspension support sub-assembly as shown in the illustration.

*a	Slot
	Outside of the Vehicle

NOTICE:

Check that the slot on the piston rod and the slot on the front suspension support sub-assembly are aligned.

(b) Align the protrusion of the front suspension support sub-assembly with the front shock absorber lower bracket as shown in the illustration.

*a	0°+/- 5°
*b	Guide Line of Front Suspension Support Sub-assembly
*c	Area in Which Protrusions Must Be Aligned
*d	Protrusion of Front Suspension Support Sub-assembly
*e	Front Shock Absorber Lower Bracket
*f	Protrusion of Upper Case
*g	Protrusion of Lower Case
	Outside of the Vehicle

NOTICE:

Make sure to install the front suspension support sub-assembly so that the protrusion of the front suspension support sub-assembly is aligned within +/- 5° of the center of the front shock absorber lower bracket.

NOTICE:

Make sure to install the front spring seat sub-assembly with insulator so that the protrusion of the upper case of the strut mounting bearing overlaps with the protrusion of the lower case within the guide lines of the front suspension support sub-assembly.

6. INSTALL COLLAR

(a) Install the collar to the front shock absorber assembly.

7. TEMPORARILY TIGHTEN FRONT SUPPORT TO FRONT SHOCK ABSORBER NUT

(a) Temporarily tighten a new front support to front shock absorber nut.

(b) Remove SST from the front coil spring.

NOTICE:

Do not use an impact wrench. It will damage SST.

8. CONNECT FRONT SPRING SEAT SUB-ASSEMBLY WITH INSULATOR

(a) Connect the end of the insulator of the front spring seat sub-assembly with insulator with the claws of the front shock absorber assembly.

NOTICE:

Make sure that the end of the insulator is securely attached to the claws of the front shock absorber assembly.
Make sure there is no excessive damage to the bellows of the insulator.
Do not allow oil, grease, etc., to contact the insulator.
If oil or grease has adhered, wipe clean with a cloth. Do not use an alcohol based cleaner.
