Rear differential will not stop groaning on any turn. Rear differential now has to be replaced and the car only has 80,000 miles on it. We also have to replace the rack and pinion. The total costs associated with both these will be well over $5,000. It is effecting the turning process when I need to turn the car. Also have a rack and pinion failure. The steering column completely locked up and the towing company had to put oil all over where the car was parked and slide it up to the cable to tow the car. Entire steering mechanism replaced but now the rack and pinion has to be replaced. I think it is due to the steering column issue. That is when it started.
