CAUTION
- Wear working clothing, including a cap, protective goggles, and protective shoes during operation.
- Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, installation, disassembly, and replacement.
- Use SUBARU genuine grease etc. or the equivalent. Do not mix grease etc. with that of another grade or from other manufacturers.
- Before securing a part on a vise, place cushioning material such as wood blocks, aluminum plate, or shop cloth between the part and the vise.
- Be sure to tighten fasteners including bolts and nuts to the specified torque.
- Place shop jacks or rigid racks at the specified points.

GENERAL TOOL DESCRIPTIONS
FRONT BUSHING
Using the ST, press the front bushing out of place. ST 927680000 INSTALLER & REMOVER SET
Scheme 48
Scheme 49
- Scribe an aligning mark on the transverse link and rear bushing.
- Loosen the nut and remove rear bushing.
Assemble in the reverse order of disassembly.
| CAUTION | Install the front bushing in correct direction, as shown in the figure. |
Scheme 50
REAR BUSHING
- Install the rear bushing to transverse link and align aligning marks scribed on the two.
- Tighten a new self-locking nut. NOTE: While holding the rear bushing so as not to change position of aligning marks, tighten the self-locking nut. Tightening torque: 190 N.m (19.4 kgf-m, 140 ft-lb)
STRUT MOUNT
Check the rubber part for creep, cracks and deterioration, and replace it with a new one if defective.
DUST COVER
If any cracks or damage are found, replace it with a new one.
COIL SPRING
Coil spring having permanent strain should be replaced with a new one. When the vehicle posture is uneven, although there is no considerable reasons like tire puncture, uneven loading, etc., check the wheel arch height referring to specifications and replace the coil spring with a new one if the measured value is out of specification.
HELPER
Replace it with a new one if cracked or damaged.
DISPOSAL
| CAUTION | Before handling gas filled struts, be sure to wear goggles to protect eyes from gas, oil or filings. Do not disassemble the strut damper or place into a fire. Drill holes before disposing of gas filled struts. |
Scheme 51
- Place the gas filled strut on a flat and level surface with piston rod fully extended.
- Using a 2 to 3 mm (0.08 to 0.12 in) dia. drill, make holes in areas shown in the figure.
Scheme 52
Scheme 53
- Jack-up the front part of the vehicle and support it with rigid racks.
- Remove the jack-up plate from lower part of crossmember.
- Remove the sub frame. < Ref. to «REMOVAL»(ref-274212-S26002088102007121400000) , Sub Frame. >
- Remove the nuts which secures stabilizer link to front transverse link.
- Remove the bolt and nut which secure stabilizer to crossmember.
Scheme 54
- Install in the reverse order of removal. NOTE: Use a new self-locking nut. Install the bushing (on front crossmember side) while aligning it with paint mark on stabilizer. Ensure that bushing and stabilizer have the same identification colors (paint mark) when installing.
- Always tighten the rubber bushing location when wheels are in full contact with the ground and vehicle is curb weight. Tightening torque: Jack-up plate to crossmember: 70 N.m (7.1 kgf-m, 52 ft-lb) Stabilizer link to front transverse link: 55 N.m (5.6 kgf-m, 41 ft-lb) Stabilizer to crossmember: 25 N.m (2.5 kgf-m, 18.1 ft-lb)
IMPROPER VEHICLE POSTURE OR IMPROPER WHEEL ARCH HEIGHT
| Possible causes | Countermeasures |
|---|---|
| (1) Permanent distortion or breakage of coil spring | Replace. |
| (2) Unsmooth operation of damper strut or shock absorber | Replace. |
| (3) Installation of wrong strut or shock absorber | Replace with proper parts. |
| (4) Installation of wrong coil spring | Replace with proper parts. |
POSSIBLE CAUSE AND REMEDY - IMPROPER WHEEL ARCH HEIGHT
POOR RIDE COMFORT
- Large rebound shock
- Rocking of the vehicle continues too long after running over bump and hump.
- Large shock in bumping POSSIBLE CAUSE AND REMEDY - FRONT SUSPENSION POOR RIDE COMFORT Possible causes Countermeasures (1) Breakage of coil spring Replace. (2) Overinflating pressure of tire Adjust. (3) Improper wheel arch height Adjust or replace the coil springs with new ones. (4) Fault in operation of damper strut or shock absorber Replace. (5) Damage or deformation of strut mount or shock absorber mount Replace. (6) Unsuitable installation (maximum or minimum length) of damper strut or shock absorber. Replace with proper parts. (7) Deformation or damage of bushing Replace. (8) Deformation or damage of helper in strut assembly or shock absorber Replace. (9) Oil leakage of damper strut or shock absorber Replace.
