Ok, so I have a 92 2wd that runs strong, kinda. Also have a 86 with a shot motor and rough tranny, but the 4wd supposedly works great. Both are auto. What else besides the transfer case and front axle needs to be swapped???

 

they used different auto trans and transfer cases for those years
I believe 2wd and 4wd transmissions were also different lengths
I doubt they will bolt up easily

you will also need the front and rear driveshafts, the 4wd shift linkage and bezel
and either the vacuum lines for the front axle actuator or bypass it

make sure the gear ratio in the front is the same as your rear axle now

 

Yea t case won't work.

 

I figured it would be more trouble than its worth. Thanks guys.

 

anything can be done it just depend on how fat the wallet is.
