Note: Before disassembling the power divider, measure and
record input shaft end-play.
See illustration for steps 1-3.
1. Position dial indicator at yoke end of input shaft.
2. Push in on input shaft and zero the dial indicator.
3. Using a pry bar, move input shaft axially and mea-
sure/record end-play.
Adjustment
Correct end-play for a new assembly is 0.003" to 0.007". The
maximum end-play for a used assembly is no more than
0.014". If end-play is incorrect, determine shim pack changes
as follows:
