I have a '97 4.6 w/ ORP and have begun to notice what appears to be the truck leaning low on the drivers side at the rear of the truck. Maybe it is just my eyes but is seems to fluctuate in variance from barely noticeable to noticeable.

Am I in need or new leaf springs? shocks? etc. I have not inspected it too well yet.

Any suggestions?

 

The gas tank is on the driver's side, that's why
