WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
- If the LH halfshaft is removed, replace the LH axle shaft seal. Refer to: Axle Shaft Seal .
-
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 24inHg of vacuum to the IWE actuator through the large port on IWE to retract the actuator.
-
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.
When installing the halfshaft, 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.
