took apart the calipers on back axle. turned out to be a peice of the dust sheild got bent and was hitting the rotor.i removed it, replaced all the break pads and metal clips on both sides and lubed all moving pieces. the break pads seemed normal except for 1 ont the inside on driver side. that one was oddly worn all the way down.

Right there! If the pads were installed wrong the pad can wear down but it may be time for calipers. Was the dust shield on the same side as that worn down pad?

While I don't think those dust shields are killing your mileage, if it were my truck, I'd want them back on. How does the parking brake cable attach on the side with the shield missing? The really smart fellas will be waking up in a couple of hours, they'll shed more light on this.

Sounds like the caliper piston or slides were stuck in order for that to happen. I would watch that corner for excessive heat/drag.

Ok, let's go back to the tires. Are they P-Metrics or LT tires on their now? If LT and you're running the air pressure the same as door sticker you're under-inflated (unless your door sticker is for an LT tire, not a P-Metric).

Did you run those little bottles of Super-Tech yet?

If all else is well I'd start eyeballing those cats. Changed mine and my mileage is finally back up to near where it was when I bought it and getting better. Haven't been driving it lately due to back pain though so no updates on its mpg journey.
