Installation Tips

Installation Notes:

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.

When cutting axles to desired lengths Currie recommends:

Normal steel cutting machinery (cold saw, band saw, chop saw, etc.)
Using a sleeve around the axle such as a small piece of PVC tubing - this allows:
- The axle to be spun in place while being cut
- A perimeter cut around the outer diameter assisting in keeping the cut square
- Avoiding the build-up of too much heat by doing a straight cut (like a knife though a stick of butter)

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.

This is perfect for small shops and will allow you to build your own custom width rear end easily. Axle length is measured from the flange to the end of the splines. All CTF axles come with a full installation package which includes one set of five 1/2"-20 Ford style wheel studs, one set of five 7/16"-20 Chevy style wheel studs, one set-20 tapered roller bearing with race, seal, & collar, and one heavy duty late model large bearing style retainer plate.

I purchased this axle because the exact replacement Currie axle has been backordered for over 2 months. We cut this one down to 26 & 3/8 inches and it worked out perfect. The bearing needs to be pressed on. The bearing retainer sleeve needs pressed on, we heated the bearing retainer sleeve up in the toaster oven first and it was still an extremely tight fit. The lug studs need to be pressed in.

The axle worked fine, but beware of the bearing retainer. It only works with drum brakes or other brakes with thin backing plates. Wilwood disc brakes require their own special bearing retainer. If the supplied retainer had an open end, like the Wilwood model, it would be an improvement. If you find that the supplied retainer does not work for your application, you'll have to cut it off.
