Installation Tips

When installing new axles in rearends with posi traction differentials, be sure to install the driver's side axle first to keep the splines properly aligned. Failure to do so may move the two splined gears out of alignment, and it may be difficult to install the driver's side axle properly if the passenger side axle is already installed.

If installation of passenger side axle is done first it may require two people when installing the driver's side axle, with both parties rotating reach axle until splines are in line and the driver's side axle fully sides into the housing.

To ensure you get the most out of your new 9 Inch components, Currie recommends that you perform a proper break-in process:

Use a name brand mineral-based gear oil, preferably 85w140 (Extremely high quality synthetic oils may be used once break-in process has been successfully performed)
Place vehicle on jack stands and let the rearend spin while the vehicle idles - run transmission in both forward and reverse periodically throughout the process
Continue to run the rearend until the pinion gets hot (place hand on bottom of the differential housing to verify this)
Proper break-in allows:
- The ability to install new axles and hit the track the same day without worry
- Extended life for rearend components
- Keeps the quality and life of your gear oil

Note: If you find that your rearend is running somewhat "tight" be sure to add Currie's 9+ Friction Modifier to "loosen up". If a more aggressive performance is desired, Friction Modifier is not needed.

The quality you would expect from Currie. Only thing lacking was instructions for mounting the axle bearing to the axle shaft. Purchased the Currie big brake kit to complement the package.
