Front Wheel Bearing and Wheel Hub: Installation

WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: While placing the wheel bearing and wheel hub into the wheel knuckle, hold the CV outboard joint with outboard pressure to maintain spline engagement with the IWE actuator gear.

Using a hand vacuum pump apply and hold 24 inHg of vacuum to the IWE actuator through the large port on IWE to retract the actuator.

NOTE: If the original wheel bearing and wheel hub is being installed, install a new wheel hub O-ring seal or damage to the wheel bearing may occur.

NOTE: Tighten the bolts in a cross pattern.

Position the front wheel bearing and wheel hub and install the 4 new front wheel bearing and wheel hub bolts.

Torque: 129 lb.ft (175 Nm)

NOTE: Measure the depth of the CV shaft threaded end to the inner bearing race (shown in illustration). The minimum depth is 15.5 mm (0.61 in). If the depth is less than 15.5 mm (0.61 in) rotate the CV shaft to clear a binding condition between the IWE and CV splines. Installing the axle nut and tightening without the proper depth of protrusion will result in damage to the IWE.

Measure the CV shaft threaded end to the inner bearing race.

NOTE: Verify the spline engagement by checking for spline lash before installing the wheel hub nut or component damage may occur.

NOTE: With vacuum still applied to the IWE.
1. Install the new the axle nut.
  Torque: 30 lb.ft (40 Nm)
2. Verify free rotation of the hub with no CV joint rotation. No clicking or grinding noise should be present.
3. Release vacuum and rotate bearing slightly to engage actuator (may hear single click when IWE system engages). Verify hub and CV joint rotate together.
