I noticed a rumble every once in a while when I drive. I notice it the most when I am gaining speed and I hit a bit of uneven road. Other than that it never makes that noise. I never thought much of it until I had my younger brother in the back seat. It really made noise then. It rumbles and seems to make the parking brake rumble and make a weird noise. Could it be my shocks are going bad in the back? Springs??? Any ideas???

 

maybe shocks
