Installation Instructions
Note #1: This kit can be installed without removing the transfer case
from the vehicle however it is recommended that the unit be removed
to ease installation of the SYE kit.
Note #2: For Jeep applications 1997 and older, use Chrysler
Connector Kit #5014007AA to replace the speedometer pickup
connector on your factory wiring harness. Your factory connector must
be cut off and this new connector spliced in. Do not alter the connector
included with the SYE kit. (see Appendix A)
1) Secure the vehicle and remove the transfer case from the vehicle.
Drain the fluid from the case. Remove the rubber boot from the rear
bearing housing by prying or cutting the steel band.
2) Remove the dust shield from the mainshaft. This can be easily
accomplished by using a chisel to dent the dust shield collar area
(where the boot band was located) in two places at 180 degrees apart
then prying the shield loose using a screwdriver. Next remove the oil
seal from the rear bearing housing.
3) Remove the mainshaft retaining ring using a pair of snap-ring
pliers. Remove the spacer below the retaining ring groove. (Fig.1).
