8.18. Identify rear bearing cap shims that have a total
stack tolerance thickness that is equal to the
drive shaft assembly end play, minus .005” to
.015” using a dial caliper. See Figure 8.18.
NOTE:
Example: Drive shaft assembly end play
minus the total stacked thickness of rear bearing
cap shims (.062” - .051”) =.011”.
8.19. Measure the thickness of a new bearing cap
gasket. See Figure 8.19.
8.20. Record the thickness of the new bearing cap
gasket _____.
8.21. Identify a rear bearing cap shim that is the same
thickness as the gasket _____.
8.22. Set the rear bearing cap gasket and shim aside.
NOTE:
The thickness of the rear bearing cap
gasket is equal to the shim thickness, therefore
neither one needs to be used in the formula
above.
8.23. Remove all three hex flange screws and wash-
ers securing the rear bearing cap in position
using a 1/2” socket. See Figure 8.23.
8.24. Remove the rear bearing cap.
8.25. Install the new rear bearing cap shims, including
the one that is equal to the rear bearing cap gas-
ket.
8.26. Install the new rear bearing cap gasket and rear
bearing cap.
8.27. Secure the rear bearing cap to the transmission
assembly with the hex flange screws and wash-
ers removed earlier using a 1/2” socket.
8.28. Torque all of the hex screws to 100 In. Lbs. using
a torque wrench and a 1/2” socket.
8.29. Pull the drive shaft assembly forward all the way,
and zero the dial indicator out.
8.30. Push the drive shaft assembly rearward all the
