My '84 does the same thing only the shocks are shot also. No you don't need to replace the springs. There are pressure vessels on each side that can leak down. It all computes into CUBIC MONEY! I am in the works of eliminating the hydro suspension on my car and going to a standard suspension...just springs and shocks. Chris
