I have a 94 Jeep Cherokee. 4.0 V6 4WD. 186K miles. I've already replaced the radiator, hoses, water pump, headlight switch, serpentine belt, tires, brakes, thermostat, and now I need to change both motor mounts, flush all fluids, fix an oil valve leak/crack, the Jeep jerks when I switch from d to r etc, the car shakes really bad if I get on the interstate, I think the steering wheel needs to b tightened, is there any experienced Jeep owners that can tell me if my Jeep is worth fixing or would I just b wasting my time and money?
