Good luck on anything you try. Sorry to say it but two things Dodge's don't do well, one is steer and the other is stop. The rigs with drum brakes in the rear need constant manual adjustment. I've tried everything and the only thing that works great is an exhaust brake with the foot brakes for the last 20 mph.
Back to the steering. I put on a new adjustable (DTT?) track bar; didn't help. Alignment doesn't help either, different tires doesn't change anything. Loaded (19K#), unloaded makes no change. Over the years I've just come to realize that when you drive a Dodge truck you have to be at attention ALL the time.
If anyone has figured out a correction, I'd like to hear about it. I don't understand how D. C. has been allowed to get away with the two most important items in a vehicle being, at best crappy, at worst lethal.
