Hopefully someone can help me out with my '99 Mercury Sable. I have a popping noise coming from my front end. The noise is not loud and it does not happen all the time but it is there. Sometimes I can feel the popping through my steering wheel as well. What do you think? CVs? Suspension? I am the original owner and my car is approaching 140,000 miles and I have never had anything on the front end worked on other than basic maintenance. Any advice or suggestions? I am trying to keep my Mercury on the road for well over 200,000. Thanks in advance!
