Quadratrac Part-Time operation ?
I just recently bought a 93 Jeep Grand Cherokee Laredo with 4.0 engine 193k miles and quadratrac drive. I've only just learned a little bit about the quadratrac system and how it's always in 4wd with 50/50 power distribution. However, it is acting like it is always in part-time operation. When I first start out while it is cold, the turning is nice and smooth with no problem and no resistance. After a while of driving and heating up, I notice I really start to feel the 4wd being on resulting in squealing tires and occasional hopping with tight turning. I have had a jeep in the past with a selec-trac system, and this 93 Grand Cherokee I have now is acting just as my other jeep has when it was in part-time operation.
I guess my question is, is the quadratrac system suppose to feel like it's in part-time operation all the time ? If that's the case then my tires will be eatin' away prematurely because of the resistance in turning. It only seems to do it after a while of driving. I also replaced the graphic display module hoping that I could select out of part-time operation, but nothing even lights up with the Full Time/Part Time/ Lo selections.. Thanks!
