Rugged Ridge NP231 Mega Short Slip Yoke Eliminator (SYE) Kit with Speed Sensor - Manual (Page 2)

Installation Instructions: 18676.72
Several suggestions that may help:
(1) The installation of this kit requires you to nearly disassemble the entire case. If
you need to rebuild, or feel like you have additional worn parts, now would be the
time to do so.
(2) Obtain a service manual for your Jeep. This will provide illustrations and
information regarding parts identification, torque values, and other important data.
(3) Use photos, and notes; mark and label all parts for future reference.
(4) Keep all bolts, nuts, washers, ect. separated into groups as you remove them.
Place inside zip-lock bags and mark location removed from.
(5) Make sure you have all the required tools, pre-lubricants, RTV sealant (OEM part
number : 82300234), thread-locker, and a clean work area.
(6) Make sure you have the time needed to perform this conversion without being
rushed.
STEP 1: Remove the transfer case from the Jeep. Drive shafts, speedometer drive unit,
linkages, etc must be removed. The case must be separated from the transmission. Refer
to your service manual for details.
STEP 2: Remove front yoke nut and yoke. Shift the range lever into the 4 Low position.
Remove the selector lever. All of these parts will be re-used.
STEP 3: Remove the output shaft boot and dust shield. Some newer models may have a
harmonic balancer. There may be other slight model variations. Refer to your service
manual for details.
STEP 4: Remove the spacer and snap ring. Remove the seal, inner snap ring (on the
shaft), and the bearing retainer ring. Remove the output housing bolts and then remove
the existing output assembly.
