Recently I have noticed a popping sound coming from the pitman arm when turning the wheels left while stationary. I don't hear the sound when rolling though. I had my wife turn the steering wheel while I was under there and I can hear/feel the pop coming from the Pitman Arm, not entirely sure if it's coming from the draglink end or the sector shaft end. I have a feeling it's coming from the draglink end though. I greased both and still having the pop. Any ideas what maybe causing this?
