11. Install two of the ring gear bolts finger tight to align the gear.
12. Press the ring gear onto the differential housing.
13. Install the ring gear bolts and cross tighten to 65-80 ft-lbs.
14. If the differential bearings were removed, install new bearings.
15. Place races onto the differential bearings and place the differential assembly onto the 3rd member.
Position the assembly so that it is just touching the pinion gear.
16. Install the bearing adjusting nuts making sure that the nuts are not cross threaded. Position the
nuts so they are in contact with the bearing races.
17. Install the bearing caps in their original locations
and torque the bolts to 12-15 ft-lbs. making sure
that the adjusting nuts still turn freely.
NOTE: In the following procedure, "Left
The differential bearing preload is set by measuring the case
spread of the 3rd member housing. As the bearing adjusting
nuts are tightened, the two differential bearing caps will be
pushed (spread) away from each other. A dial indicator must
be used to measure the case spread as the nuts are tightened.
Mount the dial indicator so that it is 4 inches above the top of
the bearing caps and parallel to the center line of the carrier
bearings.
Cross threading the nuts will damage the 3rd member housing and
bearing caps. If the housing and/or nuts are damaged, the entire 3rd
member assembly may have to be replaced.
