Ford 9 Inch Rear End - Tuff as Nails!

Here they had put together the spool assembly that consists of installing the spool bearings, applying thread lock to ring gear bolt holes, installing the ring gear, and installing spool bearing races, at which point the whole unit can be set into the center section. The last thing for the spool, before the main caps can go on, is to get the spanner nuts in place. They are the round pieces with all the holes going around it. These are for pushing in or pulling out the ring gear in relation to the pinion gear to set the backlash using a spanner wrench, hence their name.

With a mag-based dial indicator the backlash is checked. Backlash varies per application and is often between 0.008-0.012 inch. Setting the backlash has long been one of those mysteries to many people and now you can worry about it even less while Moser takes care of business for you.

The green light was given to torque the main cap bolts down to 85 lb-ft.

With the build complete and to spec, spanner nut locks are used to keep everything that way for years of trouble-free use.

The whole shoot-n-match is lovingly placed in the Jazz case ready for shipping...

And when that Jazz case gets to you this is what you get. The only difference is that our third member is housed in a nodular case instead of aluminum.

"Old Reliable" IJ has taken delivery of all the parts for our new Moser 9-inch and begins its assembly by installing the studs in the housing to mount the third member.

These come in from the inside of the housing and are sucked into position with the impact gun.

After using a little Gasgacinch, or the equivalent, on the third member gasket and mating surfaces, let things tach up and then install the gasket followed by carefully lifting the third member in place.

Installation Jason used the impact gun to snug things up and then set all every nut to 35 lb-ft with the torque wrench.

Next, the T-bolts go in the end of the axle housing to prepare for the axle installation.

Before sliding the Moser axle in place-make sure you have all the necessary brake equipment on first like backing plates or in our case the Wilwood caliper mounts/E-brake assembly. Then with a small amount of grease on the splines of the axle and the outside of the sealed bearing-carefully guide the axle into place making sure it seats all the way into the third member.

To hold everything in place is this retainer plate. It mounts on the T-bolts that come through the ends of the housing.

Use the access hole in the axle flange to snug all the nuts down.

The rearend assembly is now complete-it was that easy thanks to the smart and skillful folks at Moser Engineering. All that's needed now is to finish installing the rear brakes. Don't forget to fill the rearend with a good non-synthetic gear lube and break-in the gears when you get out on the road.
