4.7 Modifying the Bearing Cap
A clearance for the seal housing tube must be made in the
bearing cap.
4.7.1 Marking the Tube Position
With the Air Locker in place and less than 0.5mm of backlash, an
accurate measurement for the seal housing tube clearance can be
made.
NOTE : Take time and double check when taking your
measurements, as bearing caps are custom fitted to
the axle housing and cannot be replaced.
c With the seal housing tube pointing straight out, measure the
distance from a fixed position inside the differential housing to the
center of the seal housing tube. (Fig.13.)
Figure 13.
c Record your findings and recheck for accuracy.
c Remove the bearing cap from the ring gear side of the differential.
