Adjust Differential Bearing Preload
Correct differential bearing preload insures
proper location of these bearings under
load and helps position the ring gear for
proper gear tooth contact.
1. Lubricate differential bearings
2. Loosen the bearing adjuster on the same
side as the ring gear teeth until its first
thread is visible.
3. Tighten the bearing adjuster on the back-
face side of the ring gear until there is no
backlash. This can be tested by facing the
ring gear teeth and pushing the gear away
from the body while gently rocking the gear
from side to side. There should be no free
movement.
Rotate the ring gear and check for any
point where the gear may bind. If such a
point exists, loosen and retighten the back
side adjuster. Make all further adjustments
from the point of tightest mesh.
4. At teeth side of ring tighten adjuster
until it contacts the bearing cup. Continue
tightening adjuster two or three notches
and this will preload bearings and provide
approximate backlash. Measure backlash
and adjust if necessary (see following page).
