I purchased a 2002 Durango new. When changing the differential fluid the other day I noticed quite a bit of surface rust on the springs, on the frame welds, and on misc brackets under the vehicle. I am pretty surprised & kind of upset about this, I know rust happens but I didn’t think it would be this bad this soon. I want to nip this problem in the bud with but I am not sure what the best way of doing this would be. Any suggestions?
