Installation Instructions: 18676.72
WARNING!!! If you experience difficulty installing the Mega Short output housing 
check to make sure you have properly installed the speed sensor tone ring in 
accordance with step # 13. The outer edge of the sensor is sloped and must match 
the angle of the speed sensor pickup when installed. 
STEP 15: Pre-lube the surfaces on the yokes where both the inner and outer seals will be. 
Slide the yokes on and tighten the retaining nuts to 170-180 ft/lbs. 
STEP 16: Install the Magnetic speed sensor into the Mega Short output housing. It is 
important to use a small amount of oil or ATF on the o-ring to insure easy installation 
and avoid splitting and breaking the o-ring. Hand tighten the sensor retainer bolt and 
washer. Torque to 7ft-lbs. DO NOT OVER TIGHTEN, damage may occur to sensor. 
 
STEP 17: Reinstall the transfer case into the vehicle. Be sure to reinstall the drain plug 
and fill it to the recommended level with the proper fluid. Reconnect all the required 
items like the front drive shaft, shift linkages, new 3-wire connector into factory harness. 
NOTE: 4 new 5/15” – 12 point bolts have been supplied to aid with the installation of the 
rear drive shaft to output yoke. Do to clearance a standard ½” wrench can not be used for 
this application. 
IMPORTANT INFORMATION!
STEP 18: Proper rear CV-drive shaft measurements. 
Take measurements for the required CV-equipped rear drive shaft. You will need to 
replace your rear drive shaft with a new unit as the original slip yoke shaft can no longer 
be used. Measure a straight line from the transfer case rear output yoke to the rear pinion 
yoke to determine the required length of your new driveshaft. If a new drive shaft is 
needed OMIX- ADA (Rugged Ridge) does have shafts that can be purchased depending 
on your vehicles overall lift. These shafts are for general use and you may want to have a 
custom unit made if the sizes offered will not work for your application.
