Installation

Installation procedure is the reverse of removal, except for the following:

Use the seal installation tool to install the new seal.

  • When installing the halfshaft(s) into the drive unit:
    • Make sure that the opening of the snap ring is facing towards the bottom of the drive unit.
    • Do not damage or displace the oil seal.
    • Verify that the halfshaft is fully seated:
      • 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.

Check the vehicle wheel alignment, and adjust if necessary. See Four Wheel Alignment Check.
