Thanks Bobby, great info. So the torsion axle is better than the leaf spring, if I'm understanding correctly. Don't replace the axle unless necessary?
I will go over all the various places you suggested. But as a rule you don't seal the seams unless you're having leak problems? I don't think I have any leaks I was thinking of it as a sort of preventitive maintanence.
Did I mention that I love this site????
