 With the center section and...  With the center section and pinion gear out of the housing, we can see the pinion-bearing race had taken a beating.  Now you can remove the ring...  Now you can remove the ring gear from the differential. Even though we are using a new differential and gears...  ...this step must be done...  ...this step must be done because the tone ring under the ring gear needs to be reinstalled on the new differential for the anti-lock brakes to work. The tone ring can gently be tapped off the center section.  Using a punch, we removed...  Using a punch, we removed the pinion bearing races.  With the races out, clean...  With the races out, clean the housing up really good.  The tone ring is then placed...  The tone ring is then placed on the differential. The ring cannot just be pushed into place; it is a press fit. The ring is sandwiched between the ring gear and the differential.  To install the ring, place...  To install the ring, place it on the differential, and slowly warm the ring until it slides in place. Do not get it too hot; it only took a couple seconds to get ours warm enough to install.  Next, the ring gear can be...  Next, the ring gear can be installed on the differential. New bolts are supplied with the installation kit, and they should be used along with Lock-tite. The bolts are left-handed thread and get torqued to 115 lb-ft.  Now the differential bearings...  Now the differential bearings can be pressed onto the differential.  This is where things can get...  This is where things can get tricky. The pinion gear is shipped with a number written on it. Our number was 2.823. This number denotes the distance between the pinion gear face and the centerline of the differential.  This distance is changed by...  This distance is changed by adding or removing shims from between the pinion gear and the large inner pinion bearing.  When you remove the old pinion...  When you remove the old pinion bearing, take note how many shims are installed, and that could be a good starting point. We needed to add shims, and it took a couple tries to get it right.
