Removal and Installation

INFOID:0000000009886189

REMOVAL

1. Remove the rear ABS sensor. Refer to 

BRC-113, "Removal and Installation"

.

2. Remove the rear brake rotor. Refer to 

BR-36, "Removal and Installation of Brake Caliper and Disc Rotor"

.

3. Remove the parking brake assembly from the back plate. Refer to 

PB-6, "Removal and Installation"

.

4. Remove the four axle shaft bearing cage nuts and lock washers.

5. Remove the axle shaft assembly using Tools as shown.

CAUTION:

• The axle shaft bearing cup may stay in place in the axle

shaft housing. Remove the cup carefully so as not to dam-

age the inner surface of the axle shaft housing. 

• Do not reuse the axle oil seal. The axle oil seal must be

replaced every time the axle shaft assembly is removed

from the axle shaft housing.

6. Remove the snap ring from the axle shaft using suitable snap ring pliers.
7. Secure the axle shaft in a suitable vise, then use a 1/4 in size

drill bit to drill a hole approximately 3/4 into the thickness of the

bearing ring retainer [3/4 thickness is approximately 6.3 mm

(0.25 in) deep].

CAUTION:

• Mount the axle shaft using a soft jaw vise to avoid damag-

ing the axle shaft.

• Do not drill all the way through the bearing ring retainer,

the drill may damage the axle shaft surface.

8. Strike the bearing ring retainer using a suitable chisel and ham-

mer, with the chisel positioned across the drilled hole. Break the

bearing ring retainer to remove it.

CAUTION:

• Do not heat or cut the axle shaft bearing or bearing ring

retainer with a torch during removal, doing so will damage

the axle shaft. 

9. Remove the axle shaft bearing cage studs using a suitable ham-

mer or press.

• Do not tighten the Tool against the axle shaft.

• Do not heat or cut the axle shaft bearing or bearing ring retainer with a torch during removal,

doing so will damage the axle shaft. 

11. Remove the axle oil seal and discard.

CAUTION:

• Do not reuse the axle oil seal. The axle oil seal must be replaced every time the axle shaft assem-

bly is removed from the axle shaft housing.

12. Remove the wheel bearing cage.

NOTE:

• If reinstalling the old axle shaft, it may not be necessary to remove the seal plate and wheel sensor rotor.

Inspect the seal plate and wheel sensor rotor and replace as necessary. Refer to 

BRC-115, "Removal

and Installation"

.

• The wheel sensor rotor cannot be reused after it is removed. If replacing the axle shaft, install a new

wheel sensor rotor on the new axle shaft. Refer to 

BRC-115, "Removal and Installation"

.

INSPECTION AFTER REMOVAL

Axle Shaft

• Clean and remove all nicks and burrs. 

• Check for straightness and distortion. Replace if necessary.

• Inspect machined surfaces for evidence of overheating, damage and wear. Replace if necessary.

• Measure the bearing ring retainer axle journal diameter. Replace if necessary.

Axle Shaft Bearing and Cup

• Check that the axle shaft bearing and cup roll freely and are free from noise, cracks, pitting and wear.

Replace if necessary. 

Axle Shaft Bearing Cage

• Check for deformation and cracks. Replace if necessary.

Axle Shaft Housing

• Check the exterior and inner machined surfaces for deformation and cracks. Replace if necessary.

INSTALLATION

1. If installing a new axle shaft, install a new wheel sensor rotor onto the new axle shaft. Refer to 

BRC-115,

"Removal and Installation"

.

CAUTION:

• Do not reuse the old wheel sensor rotor.

2. Install the seal plate.
3. Install the axle shaft bearing cage.
4. Install a new axle oil seal.

5. Install the axle shaft bearing and cup on the axle shaft.

• Prepare an installer tool from a steel tube measuring 762 mm

(30 in) long with an outside diameter of 53.98 mm (2.125 in)

and an inside diameter of 41.28 mm (1.625 in).

• Press the axle shaft bearing and cup onto the axle shaft using

a suitable press and the installer tool, until a 0.038 mm

(0.0015 in) feeler gauge does not fit in between the axle shaft

bearing cup and seat.

CAUTION:

• Make sure the axle shaft bearing and cup, axle oil seal,

and axle shaft bearing cage are installed facing in the cor-

rect direction.

6. Install the bearing ring retainer onto the axle shaft.
