Crooked steering wheel

Good Evening all, I have a 1996 Toyota 4Runner 4WD which prior to an accident the steering wheel was perfectly fine but since then has remained crooked after many wheel alignments. My car was parked on the street near my home the next morning I approach it to drive and noticed the entire vehicle had been shifted from its original spot. Someone hit my car at the left front rim and tire. I get in to drive and the steering wheel turns almost 360 degrees ( replaced rack and pinion, clock spring, and other front end components) but still till this day after I get an alignment after 1-2 weeks of driving the steering wheel becomes crooked. I talked to many mechanics but no answers. Any idea what could be causing this? thank you!
