Timken continues to lead the hub evolution by manufacturing assemblies
that are uncompromised in quality, reliability and consistency. Proper
hub removal and installation procedures can enhance the performance
and life of hubs, axles, wheels, brakes
and other components. Following are general recommendations for removing
and installing hub assemblies.
Please note: Tech Tips is not intended to substitute for the
specific recommendations of your vehicle manufacturer. Depending on
the application, type of hub assembly and location, processes may
vary. Please review the vehicle manufacturer's recommendations before
removing or installing components. |
 |
1: Raise vehicle and
remove lug nuts and wheel.
2: Remove the brake
caliper and rotor. The brake caliper should be supported, not hanging
freely.
3: Remove the axle nut
using an axle nut socket. Use the vehicle manufacturer's instructions
regarding nut replacement. |
 |
4: If applicable,
disconnect the ABS sensor wire from its mating connector point usually
located in the wheel well or on the chassis frame. Also, disconnect
the sensor wire from the clips that are used to properly position
the sensor wire in the wheel well or frame. Before removing, make
a note of the proper orientation and positioning of the sensor wire
and bearing. |
| |
5: Remove the bolts
that attach the bearing to the steering knuckle. A puller may be required
to remove the hub assembly from the knuckle. Care should be taken
not to damage the knuckle or axle shaft.
6: Clean steering knuckle
of any debris or burrs. |
HUB ASSEMBLY INSTALLATION
 |
1: First, insert the
new hub assembly into the steering knuckle. Check the positioning
of the splines on axle shaft as the hub assembly is inserted into
the knuckle. Carefully position the two components so the splines
are not damaged during this process. Note: Never force the hub assembly
on the shaft or strike with a hammer. |
 |
2: Torque the knuckle-bearing
mounting bolts to the vehicle manufacturer's specifications using
a torque wrench. An impact wrench is not recommended. Proper torque
is required.
3: If applicable, connect
the new ABS sensor that comes already attached to the new bearing
to its mating connection point and clips in the wheel well and frame
area. |
| |
4: Install the axle
nut. Tighten the nut to the vehicle manufacturer's torque recommendations
using a torque wrench. An impact wrench is not recommended. |
 |
5: Replace the brake
rotor and brake caliper. All components should be clean from debris
and burrs.
6: Replace the wheel
and torque the lug nuts. Follow the vehicle manufacturer's recommendations
regarding torque specification and retorque requirements. |
