FRONT WHEEL HUB AND KNUCKLE
Revision: 2006 November2007 350Z
FRONT WHEEL HUB AND KNUCKLEPFP:40202
On-Vehicle InspectionNDS0000Q
Make sure the mounting conditions (looseness, back lash) of each component and component status (wear,
damage) are normal.
WHEEL BEARING INSPECTION

Move wheel hub in the axial direction by hand. Make sure there is no looseness of wheel bearing.

Rotate wheel hub and make sure there is no unusual noise or other irregular conditions. If there are any
irregular conditions, replace wheel hub and bearing assembly.
Removal and InstallationNDS0000R
COMPONENTS
REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove undercover with power tool.
3. Remove brake caliper with power tool. Hang it in a place where it will not interfere with work. Refer to BR-
26, "FRONT DISC BRAKE" .
NOTE:
Avoid depressing brake pedal while brake caliper is removed.
4. Remove disc rotor.
5. Remove wheel sensor from steering knuckle. Refer to BRC-73, "
WHEEL SENSORS" (with TCS), BRC-
128, "WHEEL SENSORS" (with VDC).
CAUTION:
Do not pull on wheel sensor harness.
6. Remove brake hose bracket from steering knuckle. Refer to BR-12, "
BRAKE TUBE AND HOSE" .
7. Remove cotter pin at steering outer socket, then loosen mounting nut.Axial end play : 0.05 mm (0.002 in) or less
1. Steering knuckle 2. Ball seat 3. Cotter pin
4. Hub cap 5. Washer 6. Splash guard
7. Wheel hub and bearing assembly

8. Use a ball joint remover to remove steering outer socket from
steering knuckle. Be careful not to damage ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to
threads and to prevent ball joint remover (SST) from com-
ing off.
9. After removing upper link, transverse link, compression rod and
cotter pin at steering knuckle, loosen mounting nut.
10. Use a ball joint remover (suitable tool) to remove upper link,
transverse link and compression rod from steering knuckle. Be
careful not to damage ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to threads and to prevent ball joint remover
(suitable tool) from coming off.
11. Remove steering knuckle and wheel hub and bearing assembly fixing bolt.
12. Remove wheel hub and bearing assembly from steering knuckle.
INSPECTION AFTER REMOVAL

About the inspection for upper link, compression rod, steering outer socket, refer to FSU-14, "UPPER
LINK" , FSU-16, "COMPRESSION ROD" , PS-17, "POWER STEERING GEAR AND LINKAGE" .
Visual Inspection

Check steering knuckle and ball seat for deformation, cracks, and other damage. Replace steering
knuckle and ball seat if cracks, deformation or other damage is found.

Check ball joint boot for deformation, damage, and also for grease leakage. Replace steering knuckle
assembly if cracks, deformation or also for grease leakage is found.
Steering Knuckle Ball Joint Inspection

Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
CAUTION:
Before measurement, move ball joint at least ten times by hand to check for smooth movement.

Hook spring balance at cotter pin mounting hole. Confirm spring
balance measurement value is within specifications when ball
stud begins moving.

If it is outside the standard, replace steering knuckle.
Rotating Torque Inspection

Attach mounting nut to ball stud. Check that rotating torque is
within specifications with a preload gauge.

If it is outside the standard, replace steering knuckle.

Axial End Play Inspection

Move tip of ball joint in axial direction to check for looseness.

If it is outside the standard, replace steering knuckle.
INSTALLATION

Refer to FAX-4, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

Wheel hub and bearing assembly and disc must be installed to
fit the marked position each other.Axial end play : 0 mm (0 in)
