Looking for help I have the rear driver side tire excessive wear inside edges. took a level across both tires and rear tire is pointed front side out about an inch. Right side is good. measured between tires and right side is 4 1/2 inches between inside of tires and right side is 6 1/2. took tire off and spring shackle bolts are easy to turn so they are loose. Looking at where the axle meets the bottom spring the axle is at the rear of the spring. all the rest of the springs and axles mounts are centered. I am thing axle shifted back and is twisted out.
Do you think loosing the shackle and pulling axle forward to same as the other side in distance apart and centered on spring.
Looking for suggestions

Thanks
