CAUTION
Ensure that the new halfshaft has a snap-ring already installed. If it does not, then install a different halfshaft that has a snap-ring already installed. Return any halfshafts without a snap-ring using the MRB process. Do not remove or reuse snap-rings.
  • Apply approximately 1 gram of Molykote M-77 Lubricant Paste only to the hub mating face on the outboard side of the halfshaft.

    CAUTION
    Do not apply any lubricant to the halfshaft splines. If lubricant is mistakenly applied, wipe the splines clean with a shop towel.
  • 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.
  • Pump the brake pedal at least 5 times to seat the pads against the brake rotors.
