I just bought a 93 Cherokee 4.0 4x4 with an automatic for $825.
I am rebuilding the motor since the existing one has a rod knock w/136K miles (It appears that the previous owner was hard on this vehicle).
Are there any things which typically fail on the 4.0 automatics which I should replace while I have it apart??
For instance, I have been told to change the rear main (these fail on the 4.0's apparently). Also I was advised to change the motor mounts and the crankshaft position sensor.
Thanks much
PS - The trannie & drive train appear to be ok....I plan on changing all the fluids.
