    Warning IconA warning icon, calling your attention to a possibly risky situation
    CAUTION
    When installing the halfshaft to the drive unit:
    • Take care not to damage or displace the oil seals.
    • Make sure that the opening of the snap rings are facing towards the bottom of the drive unit.
    • Carefully push the halfshaft into the drive unit until there is an audible "click" from the halfshaft stub contacting the pinion shaft.
    • There will be a slight pulling sensation on the halfshaft as the halfshaft circlip locks into place.
    • Pull on the inner halfshaft cup to confirm that the circlip is locked into place. If the halfshaft detaches from the drive unit then reinstall the halfshaft and then test that it is fully seated.
    • Set the LH halfshaft temporarily on the lower aft link.
  3. Swing out the upper section of the knuckle and mate the halfshaft to the hub.
  4. Align the splines of the LH rear halfshaft with those of the LH rear hub, and then install the halfshaft into the hub.
  5. Install only the axle nut onto the halfshaft, and then use a ratchet and socket to manually tighten the nut to pull the halfshaft into the hub until it seats.
