How can I make adjustments to correct hard ride condition?

Maybe your air ride switch is turned off??? It is located behind a small opening panel in the left side of the trunk. If it's on, then the problem is probably something too advanced for me to determine.

um the onlything thing that i could think of is
your stut just might be time to be replaces how old is the car what year is it
maybe it,s time to get a new bags
