Rear Axle Shaft and Wheel Bearing Removal and Installation
Removal
1) Hoist vehicle and remove wheel.
2) Remove rear brake drum and disconnect parking brake cable from brake back plate. For details, refer to Brake Back Plate Removal and Installation .
3) Drain gear oil from rear axle housing by loosening drain plug.
4) Remove wheel speed sensor (4) from rear axle housing (if equipped with ABS).
CAUTION:
• Do not pull wire harness or twist more than necessary when removing rear wheel speed sensor (4).
• Do not cause damage to surface of rear wheel speed sensor (4) or pole piece and do not allow dust, etc. to enter its installation hole.
5) Disconnect brake pipe(s) (2) from wheel cylinder and put wheel cylinder bleeder plug cap (1) onto pipe to prevent fluid from spilling.
6) Remove brake back plate nuts (3) from axle housing.
7) Using special tools indicated, draw out axle shaft with brake back plate.
Special Tool
(A) : 09942–15510
(B) : 09943–35511 or 09943-35512
8) If equipped with ABS, in order to remove sensor rotor from retainer ring, grind with a grinder one part of the sensor rotor as illustrated till it becomes thin.
9) Break with a chisel the thin ground sensor rotor, and it can be removed (if equipped with ABS).
10) In order to remove the retainer ring (1) from the shaft (3), grind with a grinder (2) two parts of the bearing retainer ring (1) as illustrated till it becomes thin.
CAUTION:
Be careful not to go so far as to grind the shaft (3).
11) Break with a chisel the thin ground retainer ring, and it can be removed.
12) Using special tools, remove bearing (1) from shaft and then remove brake back plate (2).
Special Tool
(A) : 09927–18411
(B) : 09921–57810
13) Remove stud bolt(s) (1) by using hydraulic press (2).
Installation
Reference: Wheel Bearing Inspection:Front
Install removed parts in reverse order of removal procedure, noting the following.
1) Aligning serrations between new stud bolt(s) (1) and flange, install new stud bolt(s) (1) by tightening nut (2) as shown.
3. Washer 4. Flange of axle shaft
2) Press-fit wheel bearing (1) and retainer ring (2) as shown.
NOTE:
• Use care not to cause any damage to outside of retainer ring (2).
• Refer to figure so that wheel bearing (1) is installed in proper direction.
3) For vehicle with ABS, press-fit new sensor rotor as shown.
NOTE:
Use care not to cause any damage to outside of retainer ring (2).
[A]: Vehicle without ABS [B]: Vehicle with ABS
4) Inspect axle shaft length.
Rear axle shaft length “a”
Left side: 775.5 mm (30.5 in.)
Right side: 559.5 mm (22.0 in.)
5) Apply grease to axle shaft oil seal lip (1) as shown.
“A” : Grease 99000–25010 ( SUZUKI Super Grease A )
6) Apply sealant to mating surface of axle housing (2) with brake back plate.
NOTE:
Make sure to remove old sealant before applying it anew.
“B” : Sealant 99000–31110 ( SUZUKI Bond No.1215 )
7) Install rear axle shaft to rear axle housing (2) and tighten brake back plate nuts (4) to specified torque.
NOTE:
When installing rear axle shaft, be careful not to cause damage to oil seal lip in axle housing (2).
Tightening torque
Brake back plate nut ( a ): 23 N·m ( 2.3 kg-m, 17.0 lb-ft)
8) Connect brake pipe (3) to wheel cylinder and tighten brake pipe flare nut to specified torque.
Tightening torque
Brake pipe flare nut ( b ): 16 N·m ( 1.6 kg-m, 11.5 lb-ft)
9) Tighten wheel speed sensor bolt to specified torque (if equipped with ABS).
Tightening torque
Wheel speed sensor bolt ( c ): 10 N·m ( 1.0 kg-m, 7.5 lb-ft)
1. Wheel speed sensor
10) Install parking brake cable (3) to brake back plate (1).
2. Cable stopper ring
11) Install brake shoes, referring to Rear Brake Shoe Removal and Installation .
12) Install brake drum. Refer to Rear Brake Drum Removal and Installation .
13) Refill differential housing with new specified gear oil. Refer to Rear Differential Gear Oil Inspection and Change:Rear for refill.
14) Fill reservoir with brake fluid and bleed brake system. (For bleeding operation, refer to Air Bleeding of Brake System .)
15) Install wheel and tighten wheel nuts to specified torque.
Tightening torque
Wheel nut ( a ): 100 N·m ( 10.2 kg-m, 74.0 lb-ft)
16) Upon completion of all jobs, depress brake pedal with about 30 kg (66 lbs) load over ten times so as to obtain proper drum-to shoe clearance.
Adjust parking brake cable. (For adjustment, refer to Parking Brake Inspection and Adjustment .)
17) Tighten parking brake lever cover screws.
18) Check to ensure that brake drum is free from dragging and proper braking is obtained. Then remove vehicle from hoist and perform brake test (foot brake and parking brake).
19) Check each installed part for oil leakage.
