REPLACEMENT OF LOWER ARM BUSHING
1. REMOVE LOWER ARM BUSHING
(a) Cut off the flange tip of the bushing as is shown in
the figure.
(b) Bend the remaining portions inward with a cold
chisel.
CAUTION: Be careful not to damage the flange.
(c) Bend in the flange tips and pull off the flange with apair of pliers.
(d) Using SST and a press, press out the bushing.

INSPECTION AND REPAIR OF REAR AXLE
SHAFT COMPONENTS
1. INSPECT REAR AXLE SHAFT AND FLANGE FOR
WEAR, DAMAGE OR RUNOUT
Maximum shaft runout: 1.5 mm {0.059 in.}
Maximum flange runout: 0.1 mm (0.0O4 in.)
lf the rear axle shaft or flange is damaged or worn, or if
their runout is greater than maximum, replace the rear axle
shaft.
INSPECT REAR AXLE BEARING FOR WEAR OR
DAMAGE
lf the bearing is damaged or worn, replace it.
REMOVE BEARING INNER RETAINER
(a) Using a grinder, grind down the inner retainer.
(b) Using a chisel and hammet cut off the retainer andremove it from the shaft.
REMOVE BEARING FROM SHAFT
Using SST, press the bearing off the shaft.

INSTALL BEARING OUTER RETAINER AND NEW
BEARING ON SHAFT
Using SST, press on the bearing outer retainer and new
bearing.
ssT 0951 5-20010
6. INSTALL BEARING INNER RETAINER ON SHAFT
(d Gradually heat the bearing inner retainer to about
150'C (302'F) in an oil bath.

REMOVAL OF DIFFERENTIAL
(See page RA-28)
1. DRAIN DIFFERENTIAL OIL
2. REMOVE REAR AXLE SHAFT (See page RA-25)
3. DISCONNECT PROPELLER SHAFT FROM
DIFFERENTIAL (See page RA-28)
4. REMOVE DIFFERENTIAL CARRIER ASSEMBLY
DISASSEMBLY OF DIFFERENTIAL
(See page RA-281
NOTE: lf the differential is noisy, perform the following
pre-inspection before disassembly to determine the cause.
lf the differential has severe problems, disassemble and
repair as necessary.
1. CHECK RING GEAR RUNOUT
Maximum runout: 0.07 mm (O.OO28 in.l
lf the runout is exceeds maximum, replace the ring gear.
2. CHECK RING GEAR BACKLASH
Backlash: 0.10 - 0.15 mm (O.OO39 - O.OO59 in.)
lf the backlash is not within specification, adjust the side
bearing preload or repair as necessary. (See step 5 on
page RA-36)
3, INSPECT TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION (See step 6 on page RA-38)
Note the tooth contacting position.
4. CHECK SIDE GEAR BACKLASH
Measure the side gear backlash while holding one pinion
gear toward the case.
Standard backlash:
O.OZ - 0.15 mm (0.0008 - 0.0059 in.)
lf the backlash is not within specification, install the cor-
rect thrust washers.
5. CHECK DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of the back-
lash between the drive pinion and ring gear.
Preload: 4-7 kg-cm
{3.5 - 6.1 in.-lb, 0.4 - O.7 N'm}
6. CHECK TOTAL PRELOAD
Using a torque wrench, measure the total preload.
Total preload:
In addition to drive pinion preload
2 - 4 kg-cm $.7 ' 3.5 in.-lb, O.2 - O.4 N'm)
