2000 F350 4x4. When I turn the wheel and go over bump or up a quick incline I hear a banging noise on what sounds to me like the left side. Sounds like slop in steering linkage to me. I have a little spongy steering but not bad. Lifted truck up and wiggled everything. The bar that goes from steering gear down to right side turns easily by hand, really easily. What is this bar called and where do I get it? Could this be the problem? Everything else felt tight. Truck has 265000 miles and haven't touched suspension in prob 100000. Any ideas would be appreciated
