[JM 35 Sedan]

Admiral, some of that groaning and squeaking you hear could be coming from the spring leaves lacking lubrication. I found that to be causing the problem on my '35 fordor sedan. When I took the spring pack apart, I could see the steel to steel rubbing marks and fretting corrosion around the tips of each leaf. After cleaning and smoothing those areas, and applying spring lube, most all of those noises disappeared.
