Front end wonders newbie needs help

Thanks all. I hadn't put much thought into the rear. I have some 11 year old JC whitney HD leafs back there that maybe could use some attention. They look ok, but the bushings could be defective and I wouldn't know. Otherwise I just have the same size wheels front & back and keep things pretty much stock. I did get somewhat used the effortless steering over the one week I drove it. Guess I'll have my leafs looked and - maybe new bushings installed and see what the alignment guy can do with more caster for starters.
