Since I bought my titan I have notice when I hit a bump or speed bump with any kind of speed I hear clank noise up front. After reading a lot of other threads I assume I have coil bucket contact. The truck sits nice and was leveled all ready when I purchased it. I'm not the greatest on the suspension part of our trucks how could I tell what kind of kit is on the truck and try to figure out what my noise is? I assume its the coil but not 100%.
