When my 53 Half ton was up on floor jacks, I noticed the left wheel wobble when I turned it. I exchanged it with the right one which turns true to see if my rim was bent or worse, the axle was. The results were the same. Sounds like I need a new axle. A few questions first though. What would cause this as the truck does not show signs of an accident. Would the purchase from a salvage yard be a good idea? Also, are the right and left the same and are all the 47-53 AD half tons interchangeable? Thanks again, Steve 53movinon
