Integrated Wheel End (IWE): Installation

  1. NOTE: Do not dislodge the IWE seal spring when installing the IWE on halfshaft outboard end or component damage may occur.

    Install the IWE onto the halfshaft outboard end making sure the IWE splines line up to the outboard halfshaft splines.

  9. 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.

    • Install the new the axle nut.

      Torque:

      30 lb.ft (40 Nm)

    • Verify free rotation of the hub with no CV joint rotation. No clicking or grinding noise should be present.

    • Release vacuum and rotate bearing slightly to engage actuator (may hear single click when IWE system engages). Verify hub and CV joint rotate together.
