NOTE: Specifc IWE “Integrated Wheel End” installation 
procedures are necessary when servicing and/or IWE 
vacuum is released. When the IWE actuator is loosened at 
the knuckle and/or removed from CV shaft:

•  Remove the two vacuum line, compress the IWE actuator 

and install a vacuum cap on the larger vacuum port (to 
keep it compressed).

•  Install the IWE actuator onto the halfshaft outer end (if 

removed).

•  Do not dislodge the IWE seal spring when installing 

an IWE on a CV halfshaft outboard end or component 
damage may occur. 

•  Allow the wheel knuckle to swing outward while keeping 

the halfshaft pushed inward. 

•  Once clearance is available, install the halfshaft outboard 

end into the wheel knuckle hub bearing.

•  Connect the upper ball joint and install new nut; torque to 

85 ft-lbs.

•  Install the three IWE actuator to wheel knuckle retaining 

bolts; torque to 106 ft-lbs

•  Remove the IWE vacuum cap and reconnect the vacuum 

tubes. 

•  Verify the spline engagement by checking for spline lash 

before installing the axle nut or component damage may 
occur. 

•  Install new axle nut; 30 ft-lbs
