FX4 rear suspension
I had my truck up on a lift this evening, taking care of a dragging parking brake, and I noticed that the driver's side rear suspension hung down quite a bit lower than the passenger side.
Anyone know if this is normal, and if so, why? I know some old Mopars had heaver driver side leaf springs to handle the torque to the drive wheel. I'm wondering if this is the same idea. The truck sits level on the ground.

thats pretty common on RWD and leafs.
once you get it back on the ground, make sure all of the tire pressure is exactly the same, take it for a small trip to settle the suspension and measure from the pavement to the top of the wheel opening (this will be accurate if the truck frame and body isnt smashed or tweaked) measure directly at the center of the wheel that way you can verify you are plumb/square by running the tape in line with the wheel center cap. there should be a spec somewhere about the tolerance or deviation from stock. if they are +/- 1/4 (lets say) you would then need to look into new springs (replaced in pairs)
