Thanks for the information.
Just a few more notes: This truck is completely stock, no aftermarket stuff added to improve ride except radial tires. She has new shocks all the way around and new rear springs. I have yet to find signs or any accidents so I do not think the frame is bent.
I was wondering if the torsion bar front suspension might be playing a role. Maybe one spring is weaker or worn more than the other. I always thought you could just adjust them regardless of ware: maybe I am wrong.
Thanks again for the information and I welcome any more thoughts on this. She looks 'worn out' when sitting in the parking lot at the cruise night because of the lean.
