My 2008 Grand Marques GS rides like a 3/4 ton pickup truck.
Everything seems to be fine according to my front-end mechanic. He cannot
find anything wrong with it. But he says it could have heavy duty suspension. I
hate to pay for replacement if it will still ride rough. Is this a problem with all
2008? Or all GS? The part numbers are the same for LS and GS. I bought it
used and did not realize it rode rough.
