Front Wheel Bearings Looseness Diagnosis
The following procedure describes how to inspect the front wheel bearings
for excessive looseness. In order to inspect the wheel bearings for excessive
runout, refer to
Hub/Axle Flange and Wheel Stud Runout Inspection
in Vibration Diagnosis and Correction.
Tools Required
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the front tire and wheel assembly from the vehicle. Refer
to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- If the vehicle has ABS,
remove the bolt (2) and the front wheel speed sensor (1) from
the steering knuckle. Position the sensor to the side.
- Remove the front brake hose bolt and the hose from the strut.
Position the hose and the bolt to the side.
Notice: Do not allow the brake components to hang from the flexible
brake hoses. Damage to the brake hoses could result.
- Remove the front brake caliper housing and the brake caliper bracket.
Suspend the caliper housing with wire in order to prevent damage to the brake
hose. Refer to
Brake Caliper Bracket Replacement
in Disc Brakes.
Notice: Use care in order to not damage the boot and the inner oil seal.
Notice: On vehicles equipped with ABS, use care to not damage the
speed sensor rotor of the drive axle.
- Remove the brake rotor. Refer to
Brake Rotor Replacement
in Disc Brakes.
- Place the J 8001
with the J 26900-13
near the center of the axle hub.
- Push and pull the hub flange.
- Use the J 8001
in order to measure the looseness of the wheel bearings.
Specification
The maximum wheel bearings looseness is 0.05 mm (0.0020 in).
- Replace the front wheel bearings if the measurement exceeds the
specification. Refer to
Front Wheel Hub, Bearing, and Seal Replacement
in Front Suspension.
- Install the brake rotor. Refer to
Brake Rotor Replacement
in Disc Brakes.
- Install the brake caliper bracket. Refer to
Brake Caliper Bracket Replacement
in Disc Brakes.
- Install the brake pads, the insulators, the retainers, and the
wear indicator. Refer to
Brake Pads Replacement
in Disc Brakes.
- Install the brake caliper. Refer to
Brake Caliper Replacement
in Disc Brakes.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- If the vehicle has
ABS, install the front wheel speed sensor (1). Secure the sensor to
the knuckle with the bolt (2).
Tighten
Tighten the bolt to 7.8 N·m (69 lb in).
- Install the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle.
Rear Wheel Bearings Looseness Diagnosis
The following procedure describes how to inspect the rear wheel bearings
for excessive looseness. In order to inspect the wheel bearings for excessive
runout, refer to
Hub/Axle Flange and Wheel Stud Runout Inspection
in Vibration Diagnosis and Correction.
Tools Required
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- If the vehicle has ABS,
remove the bolt (2) and the wheel speed sensor (1) from the
knuckle.
- Remove the brake drum. Refer to
Brake Drum Replacement
in Drum Brakes.
- Place the J 8001
with the J 26900-13
near the center of the axle hub.
- Push and pull the hub flange.
- Use the J 8001
in order to measure the looseness of the wheel bearings.
Specification
The maximum wheel bearings looseness is 0.05 mm (0.0020 in).
- Replace the rear wheel bearings if the measurement exceeds the
specification. Refer to
Front Wheel Hub, Bearing, and Seal Replacement
in Rear Suspension.
- Install the brake drum. Refer to
Brake Drum Replacement
in Drum Brakes.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.

the knuckle with the bolt (2).
Tighten
Tighten the bolt to 7.8 N·m (69 lb in).
- Install the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle.
