upper control arms
 

Lately my car has been riding really harsh. I just had rear shocks put on and it semmed to help for about a month and now its bad in back but worse in the front. My dad works for ford and he said that the springs dont go bad there just a dampener. I read and article in a mustang magazine that the upper control arms can go bad a squeak. It just seems like the tires just want to blow throught the floor everym time i hit a bump. Any thoughts would be good

You say it's riding harsh as in stiff, or harsh as in extreme reaction to bumps?

If they are crappy shocks they can go out in a couple of months.
