What would cause an intermittant pop when turning nearly full over left at low speed. It "feels" like it might be a strut. Would a strut make a pop when turning sometimes or could the steering rack be bad inside? I checked the ball joints and tie rod ends - no "play" and I lubed all grease fittings I could find. I jacked up the front of the car and wiggled the wheels - all is normal, bearings seem fine, turned the steering lock to lock with no noises or oddities found. Steering rack mounts are tight, power steering pump is full and quiet, etc.... I can find nothing out of the ordinary - please help!
