Removal And Installation: Installation

WARNING: This page is about a different car, the 2004 Infiniti M45. However, it is still accessible from the selected car via links, so may be relevant.

Paying attention to following items, install in the reverse order of removal.
1. Install the propeller shaft onto the rear final drive companion flange while aligning the matching marks that are marked during removal.
2. Adjust position of the bearing cushion so as not to apply thrust play to the center bearing insulator.
3. Position the bearing cushion overlap as shown in the figure.
4. Install the center bearing bracket (upper) with its arrow mark facing forward.
5. Tighten the center bearing mounting bracket (upper) fixing nuts to specified torque.
  CAUTION: Do not reuse the nuts. Always replace the nuts with a new one.
If companion flange has been removed, put new alignment matching mark B on it. Then, reassemble using the following procedure.
Perform these steps when either of final drive and shaft is replaced with a new one.
1. Erase original mark B from companion flange with suitable solvent.
2. Measure companion flange vertical runout.
3. Determine the position where maximum runout is read on dial indicator. Put mark (shown by B in figure) on flange perimeter corresponding to maximum runout position.

If the propeller shaft or final drive has been replaced, connect the propeller shaft and final drive as follows:
NOTE: Avoid damaging the rebro joint boot, protect it with a shop towel or equivalent.
- Install the propeller shaft while aligning its matching mark A with the mark C on the joint as close as possible.
- Tighten the joint bolts/nuts to specified torque.
  CAUTION: Do not reuse the bolts, and washers. Always replace them with new ones.

- After installation, check the vibration by driving the vehicle. If the vibration is present, remove the propeller shaft from the final drive companion flange.
- Turn the propeller shaft 60, 120, 180, 240 or 300 degrees and reinstall the propeller shaft to the companion flange, then measure the runout again by driving the vehicle on each angle position.
