DISASSEMBLY
1. CHECK COMPANION FLANGE RUNOUT
Using a dial indicator, measure the vertical and lateral runout of
the companion flange.
Maximum: runout: 0.09 mm (0.0035 in.)
If the runout exceeds the maximum, replace the companion
flange.
2. CHECK RING GEAR RUNOUT
Using a dial indicator, measure the ring gear runout.
Maximum runout: 0.05 mm (0.0020 in.)
If the runout exceeds the maximum, replace the ring gear.
3. CHECK RING GEAR BACKLASH
Using a dial indicator, while holding the companion flange, mea-
sure the ring gear backlash.
Backlash: 0.13 ± 0.18 mm (0.0051 ± 0.0071 in.)
HINT:
Measure at 3 or more positions around the circumference of the
ring gear.
If the backlash is not within the specified value, adjust the side
bearing preload or repair as necessary.
4. CHECK TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION (See page SA±119)
5. CHECK SIDE GEAR BACKLASH
Using a dial indicator, measure the side gear backlash while
holding one pinion gear toward the case.
Backlash: 0.05 ± 0.20 mm (0.0020 ± 0.0079 in.)
If the backlash is not within the specified value, replace the side
gear thrust washer of the different thickness (See page
SA±119).
