Re: 94 Jeep Cherokee - part time 4wd Won't disengage
Vito,
I don't have one of these systems, but one of the symptoms, that you might
expect from a posi-traction unit, that needs the fluid changed, could be
grabbing similar to what you describe. Hopefully, what you are seeing is
just a sign of deferred maintenance. I would start by making sure that all
the fluids are of the proper type, clean, and at the proper level. In
practice, with a used vehicle that you have just bought, the only way to
know for sure is to change everything.
If you can contact the previous owner, that might shed some light. I have
had people contact me regarding vehicles I have sold or traded in, and I
didn't mind.
