  3. 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.
