Tire Cupping

Tire Cupping
When I bought my truck I put new tires and shocks on it. That was 2,300 miles ago. The front passenger side tire is cupping bad.
I took the truck back to the shop where I got the tires and they said it was a bad track bar. To me if that was the case both front tires would be cupping.
This shop as a reputation for not know what the hell they are doing except for putting on tires.
Anyone got any other ideas?

Mine did the same thing. For me it was a bad wheel bearing hub (driver's side) and bad alignment.
Do what zman17 said and check it yourself. Jack up the front end of the truck and (safely) push/pull on everything including the wheels under the truck.
Then set the truck back on its wheels and have someone get into the truck, start it and turn the steering wheel back and forth while you watch the track bar and other joints under the truck.

Because they put the tires on there and they will be the only shop that will replace the tires if it was a defective tire.

Look into "Luke's Links," if you're handy, to rebuild and strengthen the ball joint end of your track bar (and any other of your tie rods for that matter).
But even with a bad trackbar end, I doubt that would cause cupping on one tire. Check your wheel bearing hubs and ball joints. Jack the truck up, grab the tire at the top and bottom and try to get it to move virticaly. If it does, it's likely you have a bad wheel bearing (if the tire also moves side/side) or ball joint.

Nope. Shouldn't move at all if the joint is good.

There is no one spot it is wearing, it is pretty well over the whole tire.
