I had a mechanic that claims that they replaced the rack and pinion system on my car. Recently I found that some of the other work he claimed to have done wasn't done. Is there an easy way to check if a rack and pinion system has been replaced from standing next to the car? I don't have jack stands nor do I know much about auto mechanics. I just know that my power steering reservoir was completely empty earlier today and it happened quickly. I didn't have problems until I drove about 5 miles. Car doesn't get driven much.
