Measure the hub and drum starting force. Service limit 22 N (2.2 kg, 4.9 Ibs.) or less 4. If the hub and drum starting force exceeds the limit, remove the hub cap, loosen the wheel bearing nut and retighten it, and recheck the hub and drum starting force. 5. If the hub starting force is still beyond the limit, replace the bearings. NOTE There should be no axial clearance for hub and bearing. REAR SUSPENSION 55-7 REAR SUSPENSION TORQUE : Nm (kg.cm, Ib.ft) REMOVAL 1. Support the side frame on a jack stand. 2. Remove the rear brake assembly. 3. Remove the muffler. 4. Jack up the suspension arm and keep it slightly raised. 5. Remove the shock absorber. CAUTION When removing parts such as fuel tank, rear suspension, etc. use a hydraulic floor jack at the front of vehicle (Refer to GENERAL GROUP), to prevent the vehicle from tilting. 55-8 REAR SUSPENSION 6. Lower the jack. Remove the coil spring and temporarily install the shock absorber to the suspension arm. 7. Disconnect the brake hose at the suspension arm and remove the rear suspension arm from the body as an assembly. INSPECTION 1. Check the suspension arm for distortion or damage. 2. Check the suspension shaft for distortion or damage. 3. Check the dust cover for damage. 4. Check the shock absorbers for malfunction, oil leakage or noise. 5. Check the coil springs for deterioration, cracks or damage. 6. Check the spring seats and bump stoppers for damage. 7. Check the stabilizer bar for damage. DISASSEMBLY 1. Before the fixtures are removed, make alignment marks on the fixtures and suspension arms for reference during reassembly. 2. Loosen the nuts at both ends of the suspension arm to remove the fixtures and rubber bushings. 3. Before the rear suspension on cars with a rear stabilizer bar is disassembed, put aligning marks on each end of the stabilizer bar in alignment with the punch mark on the stabilizer bar bracket. Then, while the rear suspension is separated into the right and left arms, remove the stabilizer from the bracket. REAR SUSPENSION 55-9 4. Remove the dust cover clamp. 5. Separate the suspension arm into the right and left arms. Leave the dust cover attached to the right suspension arm to protect the lip from damage. 6. Remove the rubber stopper from the right arm 7. Using a flat-blade screwdriver, remove bushing A. 8. Using a hammer and drift, drive bushing B out of the left suspension arm. REASSEMBLY 1. Apply the specified grease to the inside of the left suspension. 55-10 REAR SUSPENSION 2. Using special tools (09555-21100, 09555-21000), drive bush- ings B and A, in that order, into the suspension arm. CAUTION 1) Apply grease to all outside surfaces of bushings B and A. 2) Drive bushing B in until the notch on the special tool (09555-21000) reaches the end of the suspension arm. 3. When replacing the dust cover, insert a new one up to the center position (stopper) of the right suspension arm. 4. After applying grease to the surface of the right suspension arm, install the rubber stopper. 5. Slowly push the right and left suspension arms together. Wipe away the surplus grease. Align the marks on the stabilizer bar and the stabilizer bar bracket. 6. Install the rubber bushings, fixtures and washers. 7. After aligning the fixtures with the suspension arms according to the alignment marks, loosely tighten the nuts. CAUTION 1) Install the washers and fixtures in the correct direction and position as shown. 2) Tighten the nut to specification with the vehicle low- ered to the floor. REAR SUSPENSION 55-11 8. Pack grease in the dust cover and lips, and secure the dust cover with the clamp. INSTALLATION 1. Tighten the fixture attaching bolts to the specified torque. 2. Install the coil springs. 3. Loosely install the shock absorbers. CAUTION Tighten the nut to specification with the vehicle lowered to the floor. 4. Install the rear brake assembly. 5. Install the wheel and tire assembly. 6. Lower the vehicle and tighten the suspension arm end nuts and shock absorber bolts to the specified torque. 7. Bleed the brake system. 8. Adjust the rear brake shoe clearance. 55-12 REAR AXLE HUB REAR AXLE HUB COMPONENTS TORQUE : Nm (kg.cm, Ib.ft) REMOVAL 1. Jack up the rear of the vehicle and support it on jack stands. 2. Remove the wheel and tire. 2. Remove the brake drum. DISASSEMBLY 1. Using a flat-blade screwdriver, remove the oil seal from the drum. REAR AXLE HUB 55-13 2. After removing grease from inside the hub, remove the bearing outer races, using a hammer and drift. INSPECTION 1. Check for a damaged or worn bearing. 2. Check for a worn or damaged brake drum inside surface. ASSEMBLY 1. After applying the specified grease to the bearing surface, drive the bearing outer races into position. 2. Install the inside bearing inner race. 3. Install the grease seal and apply grease to the seal lips. NOTE Be sure to use a new grease seal. 4. Install the outside bearing inner race. 55-14 REAR AXLE HUB INSTALLATION 1. Before installing the rear hub assembly, inspect the rear wheel bearing nut using the following method to determine whether it is reusable or not. 1) Screw in the rear wheel bearing nut on the spindle untill the gap shown in the illustration is achieved. 2) Measure the torque required to rotate the rear wheel bearing nut while backing it off (turning it counter-clock wise). Limit : 5.5 Nm (48 ft.lbs.) 3) If the measured torque is less than the limit, replace the rear wheel bearing nut with a new one. 2. Install and tighten the self-locking nut to the specified torque. Check the wheel bearing for end play and starting force. (Refer to Page 55-6) 3. After filling the hubcap with multipurpose grease, install the hub cap.
