I have a 2002 SL1 with only 16,856 actual miles on it. I'm hearing a thumping sound under the car sometimes while driving.
I want to sell my Saturn but just this week I'm hearing a thumping sound from
under the center of the car sometimes when I'm driving. It seems to make
the noise going over a bump, like something is bouncing and hitting the
bottom of the car but it's infrequent. I had a new muffler and converter done
four years ago and had to have the front driver side spring and struts done
three years ago. I don't want to put any money into the car but feel I can't sell
it with the thumping noise. If I knew what it was and the cost to fix it then I
could tell potential buyers of the issue.
