The first step in this job is to remove the axles from rear housing.
Install the pinion on the pinion support and set the preload at 25 inch-pounds.
Here is the Detroit Locker.
Here is the carrier.
Check the side caps for alignment.
Install new bearings in the carrier.
Here is the new ring gear and the already installed pinion gear.
A .030 shim is fitted to the pinion support. In this case it does the trick, but other shims may be needed in your install.
Install the pinion support on the carrier and torque to 40 ft-lb.
Fit the ring gear onto the locker.
Turn the locker over and install the ring gear bolts. Use red LocTite and torque to 40 ft-lb in a crisscross pattern. Then, torque to 60 ft-lb.
Place the locker into the carrier and oil all bearings with 80-90-weight gear lube.
Install the locker into the carrier along with the preload adjusters and side caps.
Use a dial indicator to check backlash. These gears called for .008 to .010.
Adjust the preload adjusters with a special tool. Move them one hole at a time until you get the correct backlash.
Once the backlash is correct, anchor the preload adjusters with lock tabs and torque to 10 ft-lb.
Tighten the side caps to 45 ft-lb and then to 80 ft-lb in two stages.
Next, paint a section of the ring gear with the white lead paint that comes with the ring and pinion gear.
Preload the assembly as you turn it by providing resistance with a screwdriver to put pressure on it at the pinion. This will mimic power being applied.
Keep checking the pattern between the ring and pinion until it is perfect. This involves pulling out the pinion support and changing shims as many times as it takes. The pattern should look like this.
Now that everything is complete, install the carrier into the housing.
Next, reinstall the axles.
Now all that's needed is the blown big block and this Camaro will be on its way.
