Air Conditioner problems of the 2000 Buick Regal

My major concern is when I went to replace my tires today goodyear LS eagles I was told the tie rods were worn so badly that they could not do it without replacing them to align the car properly. There had been a noise in the front of the car since the day one that I thought was normal tire noise, based on my years of driving (37 without incident) it seems worn tie rods at 31,000 miles is something to consider investigating. My driving is local 90% of the time, 7 miles each way to work, 5 days a week. Once a month a trip to boston. I took the opportunity to report the other little incidental problems that do not have an immediate effect on my safety, the exception being the air bag light coming on and off intermittently. I have not reported these minor probelms to the dealer. I have reviewed the recall notices for my Buick Regal and based on my VIN number I am hoping NHTSA can let me know if all the recall work has been performed. I purchased the car new in July 2000 and I am only aware of two recalls that required us to replace the labels on our visors and return to the dealer for seat belt assembly. I have never been contacted for the other reported recalls although they occurred in may 00 and June 00 and I did not purchase the car until 7/29/00. Is it safe to assume the recalls in may and June were performed on my car if it was one of the vehicles in need? dt.

Severe rattle from front of vehicle at low speeds, 20-30 mph over washboard surfaces. Dealer replaced left front hub but still occurs. In regards to the a/c, groaning from a/c on and off while car is running. Dealer replaced compressor but still happens daily.
