3. Using two sets of feeler gauges, insert a feeler

stock of sufficient thickness between each
bearing outer race and the carrier to remove all
end play. Make certain the feeler stock is pushed
to the bottom of the bearing bores.
Mount the dial indicator J–8001 on the carrier so
that the indicator stem is at right angles to a tooth
on the ring gear.

4. Adjust feeler gauge thickness from side to side

until ring gear backlash is in the specified range.

Backlash: 0.13–0.20 mm(0.005 –0.008 in)

With zero end play and correct backlash estab-
lished, remove the feeler gauge packs, determine
the thickness of the shims required and add 0.025
mm (0.001 in) to each shim pack to provide side
bearing preload. Always use new shims.

5. Use bearing remover J–42379 and pilot

J–8107–2 to remove side bearing.
