I have a 2002 Lincoln LS V8 and am experiencing a "thudding" noise (sounds sort of like a hollow thud) over pretty much any bump I go over in the road. Driving the car down the road I feel a vibration that almost feels like I've got flat spots in several tires. I really doubt that I have any flatspots in the tires because once I've driven around for a while the vibration doesn't really disappear.
I was wondering if anyone had any ideas about what the problem might be before I end up having to take it to the shop. Are there any known suspension problems with the 2002 LS? The car has right around 20,500 miles on it.
