The rear shocks seem to be very firm and I think it has an air pump to inflate on 2001 Buick Park Avenue

The car has a rough ride now and what seems to be an air pump runs alot more often than usual, we have only had this car for a few months. Need more info to know if the shocks need replacement or is it the air pump

could be the shocks.. Remove the shocks- fully extend, them plug the opening that the the air lines hook to .. Fill a tub (that will fit the shocks ) with water- submerge the shocks in the water and compress them - if you see bubbles them you know that they need replaced.
