sary.

ship nuts for any gaps between the mating surfaces.
Note:
Be sure to repeat steps 2 and 3 for all center bearing
end fittings for broken back and backlash.
2.

ness.

If looseness is evident, retighten center bearing bracket
bolts. Consult the vehicle manufacturers’ specifications
for proper bolt torque. Check the alignment of the
bracket before tightening the bolts. Bracket should not
be skewed.

Visually inspect the center bearing rubber cushion
for damage. Make sure the slingers are not rubbing
against the rubber cushion. Verify that the rubber
cushion is properly seated in the metal bracket.
