I like others have had trouble with my 1999 Pantera III Trailer making strange noises which I thought was the springs… Not So!!!Took the trailer in this week for state inspection with my trailer guy and discussed this with them. Well the culprit turned out to be the equalizer mechanisms and the spring bushings.Installed new equalizers both sides and all new spring bushing and problem solved!!!The trailer is quiet as its suppose to be!!
