If you have a Cherokee Application:
You will also need to confirm the universal joint size at the rear differential (dimension E).

This dimension will be either 3-7/32" or 3-5/8".  

 

You should identify the model of the transfer case.

Is there a port for the shift position sensor in the speedometer housing?


Is the speedometer driven through the transfer case? If it is, the housing will be machined to accept the speedometer driven gear assembly. Or is this portion of the housing cast but not machined?

 

 



Measure for length:

If you have a late design transfer case with the rubber boot that attaches to the slip yoke on the drive shaft, measure from the slinger on the rear out-put of the transfer case (this will be the leading edge of the rubber boot) to the center of the universal joint at the rear differential. From this original dimension, we will be able to determine the required length of the drive shaft as an end result.

If you have an early model transfer case, simply measure from the outermost lip of the rear out-put seal on the transfer case to the center of the joint at the differential end. From this original dimension, we will be able to determine the required length of the drive shaft as an end result.
