bed height
I got a tape measure, and measured at the top of the rear wheel well lip, the left side is ~1/2 inch lower than the right. The front fenders are the same height.
Anyone have any experience with this? Can this be fixed? It looks like the bed bolts directly onto the frame, so without torsion bars it looks to me like shims are the only thing to be done.
Anyone?
Fairly common, as the fuel tank is on the left side, more weight equal a little more sag on that side. I believe a 1/2 - inch is within spec. Tech folder is down currently so i can't verify the number for you.
Hope this helps
Found it.
"99-05 F-SuperDuty Rear Suspension Lean:
This applies to rear suspension lean only. The truck needs to be parked on a level surface with no load (or at least loaded evenly) and all tires inflated evenly. Inspect for spring damage or shackle bushing wear. Measure vertically from the lowest point of the wheel rim (not from the ground) to the wheel lip. If the measurment is within 3/5" from side to side, no action is required. If the measurement is greater than 3/4", measure the gap from the top of the axle to the rebound bumper bracket. If this measurment is within 3/4", inspect the body mounts and have the frame checked. If the measurement is between 3/4-1", install shim 3C3Z-5A300-AA on the low side, between the spring spacer and spring seat. If the measurement is between 1-1.75", install shim 5C3Z-5742-AA on the low side. If the measurement is greater than 2", replace the spring. Install longer U-bolts if necessary.
