CAUTIONIf reinstalling the half shaft 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 half shaft into the drive unit until there is an audible "click" from the half shaft stub contacting the pinion shaft.
- There will be a slight pulling sensation on the half shaft as the half shaft circlip locks into place.
- Pull on the inner half shaft cup to confirm that the circlip is locked into place. If the half shaft detaches from the drive unit then reinstall the half shaft and then test that it is fully seated.
- Align the splines of the LH rear half shaft with those of the LH rear hub, and then install the half shaft into the hub.
