I have a 98 wrangler sport. lifted (4 inch) with off road tires. really a sharp rig. in first gear (5 speed) at very low speeds (backing out of driveway, etc) when I turn the steering wheel I get an odd moan/whine type sound which appears to be coming from the steering column itself. any ideas what might be going on? I hate to take it in and spend an arm and a leg if anyone else knows what might be up.
