Frame And Members problems of the 2000 Dodge RAM

Tire is cut into on left turns and u turns by a-frame. Returned to weisner (Dodge dealer nearest my home) they informed me it was a problem with the 2000 Dodge Ram pickups. They told me the only thing I could do was have the a-frame ground with a grinder. I the took it to the dealer I purchased it from and they told me it was a Dodge problem and they would contact them. When I didn't hear from them I contacted Dodge myself and they told me there was nothing they could do to fix it. The last dealer (dowell motors) even put a new truck on the rack next to mine and it does the same thing. Truck is still under warranty. If not careful not to make sharp turns I will cut through entire sidewall of my tire. Have rotated several times.
