Front Suspension: Removal & Installation Subaru Forester SG рестайлинг

INSTALLATION

1. Install the ball joint onto housing. Tightening torque (Bolt): 50 N.m (5.1 kgf-m, 37 ft-lb) CAUTION: Do not apply grease to tapered portion of ball stud.
2. Connect the ball joint to transverse link. Tightening torque (Castle nut): 40 N.m (4.1 kgf-m, 30 ft-lb)
3. Retighten the castle nut further within 60° until a slot in castle nut is aligned with the hole in ball stud end, then insert a new cotter pin and bend it around castle nut.
4. Install the front wheel.

1. Measure the play of ball joint by the following procedures. Replace with a new one when the play exceeds specified value. With 686 N (70 kgf, 154 lb) loaded in direction shown in the figure, measure the dimension l 1 With 686 N (70 kgf, 154 lb) loaded in direction shown in the figure, measure the dimension l 2 . Calculate plays from the following formula. S= l 2 - l 1 When plays are larger than the specified value, replace with a new one. FRONT BALL JOINT Specified play for replacement: S Less than 0.3 mm (0.012 in)
2. When the play is smaller than specified value, visually inspect the dust cover.
3. The ball joint and cover that have been removed must be checked for wear, damage or cracks, and any defective part must be replaced.
4. If the dust cover is damaged, replace with a new ball joint.

1. Remove the wheel.
2. Remove the bolt securing brake hose from strut.
3. Scribe an alignment mark on the camber adjusting bolt which secures strut to housing.
4. Remove the bolt securing ABS wheel speed sensor harness.
5. Remove the two bolts securing housing to strut. NOTE: While holding the head of adjusting bolt, loosen self-locking nut.
6. Remove the three nuts securing strut mount to body.

1. Install the strut mount at upper side of strut to body, and then tighten with nuts. Tightening torque: 20 N.m (2.0 kgf-m, 14.5 ft-lb)
2. Position the aligning mark on camber adjustment bolt with aligning mark on lower side of strut. Install the strut to housing with a new self-locking nut. NOTE: While holding the head of adjusting bolt, tighten self-locking nut. Tightening torque: 175 N.m (17.8 kgf-m, 129 ft-lb)
3. Install the ABS wheel speed sensor harness to strut. Tightening torque: 33 N.m (3.4 kgf-m, 24.3 ft-lb)
4. Install the bolts which secure brake hose to strut. Tightening torque: 33 N.m (3.4 kgf-m, 24.3 ft-lb)
5. Install the wheels. NOTE: Check the wheel alignment and adjust if necessary.

1. Using a coil spring compressor, compress the coil spring.
2. Using the ST, remove the self-locking nut ST 927760000 STRUT MOUNT SOCKET
3. Remove the strut mount, upper spring seat and rubber seat from strut.
4. Gradually decreasing the compression force of compressor, and then remove the coil spring.
5. Remove the dust cover and helper spring.

1. Before installing the coil spring, strut mount, etc., on the strut, check for the presence of air in the damping force generating mechanism of the strut since air prevents proper damping force from being produced.
2. Checking for the presence of air Place the strut vertically with piston rod facing up. Move the piston rod to center of its entire stroke. While holding the piston rod end with fingertips, move the rod up and down. If the piston rod moves at least 10 mm (0.39 in) in the former step, purge air from the strut.
3. Air purging procedure Place the strut vertically with piston rod facing up. Fully extend the piston rod. With the piston rod fully extended, place the piston rod side down. The strut must stand vertically. Fully contract the piston rod. Repeat three or four times from the first step. NOTE: After completely purging air from the strut, be sure to place the strut with piston rod facing up. If it is laid down, check for entry of air in the strut as outlined under "Checking for the presence of air".
4. Using a coil spring compressor, compress the coil spring. NOTE: Make sure that the installing direction of coil spring is as shown in the figure.
5. Set the coil spring correctly so that its end face fits well into the spring seat as shown in the figure.
6. Install the helper and dust cover to the piston rod.
7. Pull the piston rod fully upward, and install the rubber seat and spring seat. NOTE: Ensure that upper spring seat is positioned as shown in the figure.
8. Install the strut mount to the piston rod, and then tighten a new self-locking nut temporarily.
9. Using a hexagon wrench to prevent strut rod from turning, tighten the self-locking nut with ST. ST 927760000 STRUT MOUNT SOCKET Tightening torque: 55 N.m (5.6 kgf-m, 41 ft-lb)
10. Loosen the coil spring carefully.

1. Install in the reverse order of removal. CAUTION: Always tighten the rubber bushing when tires are in full contact with the ground and vehicle is curb weight. Tightening torque: Transverse link bushing to crossmember: 125 N.m (12.7 kgf-m, 92.3 ft-lb) Stabilizer to bushing: 25 N.m (2.5 kgf-m, 18.1 ft-lb) Tie-rod end to housing: 27.0 N.m (2.75 kgf-m, 19.9 ft-lb) Front cushion rubber to crossmember: 85 N.m (8.7kgf-m, 62.7 ft-lb) Universal joint to pinion shaft: 24 N.m (2.4 kgf-m, 17.4 ft-lb) Crossmember to body: 100 N.m (10.2 kgf-m, 74 ft-lb)
2. Purge air from the power steering system. < Ref. to «POWER STEERING FLUID»(ref-274219-S17858847462007121400000) . >
3. Check the wheel alignment and adjust if necessary.

Install in the reverse order of removal.

Note. Replace the M12 bolt with a new one.
