I have a 2003 Hyundai Sonata that when I drive it I hear a thumping noise. One person has suggested that it is a tire and another has said maybe a wheel bearing. I hope that I can get a perfessional assesment on this problem.
Do all of these have timing chain tensioner issues?
The majority of them do. There is an updated tensioner that is now available. The New Part Number is 24410-3c300. This is noted in the Technical Service Bulletin #06-20-002
