My mom just purchased a used jeep liberty this weekend, well she came to show me her can and complained that the steering was stiff at low speeds (parking) well I checked to see if the 4x4 was engaged but it says its in 2X high. So this should mean that it is transferring to rear tires but it seems to be driving in 4x4. Does anyone have any insight on what to check?? This is a 2002 model... Thanks for the help in advance.
