95 Ford F-150 200,000 plus miles. Steering wheel very loose. Recently replaced power steering pump due to hard to steer and catching & whine.Easy to steer but now the wheel catches like it is caught on something then stops and is fine but still play in wheel. Now as going down the road it seems to pop out of gear. The gear shift doesn't but trans does and engine revs like in park. Let off accelerator and it works. Another problem is the ignition is loose, turn off truck and remove key it is not in off position and without key you can turn ignition to off position. What could be the problem?
