2011 F150 transmission and rear tire problems

I have a 2011 F150 purchased in March. the first month it developed a transmission leak. The dealer replaced the gasket. Shorly after it stared having about a 4 second lag going into reverse. Now has developed a lag going into drive. The dealer says it looks like torque convertor problem. Then when it was in for service at 25000 the dealer said the rear tires are so worn on the inside they cant rotate them. Its still in the shop for the trans. issue and they plan on seeing if the rear end may be out of line. Anyone else had this kind of problems

I have seen issues with the torque converters on the Superduty trucks. They are made in Mexico and being shipped and installed with metal shavings in them from the machining process. this, in turn, pumps crap into the rest of the transmission. My brother in-law worked for a machine shop and the Superduty plant here in town had sent them some samples to see if there was a machining issue with them, and it turns out, they are full of shavings. I'm sure the F150 units probably come from the same place. Very sad.
Use to be quality is job 1. Not so much these days. Cheapest supplier is job 1. A common problem everywhere these days. Another reason that China is flourishing while we are in bad shape.

As for the rear tires, the rearend is mounted on the leak springs with locator pins and unless one has broken and the rearend has shifted, there isn't any alignment for it. You can drive behind it and see if it is "dog legging" like an old Nova or not. The tires can not leak in at the top unless the axles are not straight and that is almost impossible.

Wouldnt it be possible to weld the tubes to the axle housing out of alignment? Or perhaps the tubes were bent prior to assembly?

It sounds like the OP has a Toe-out type of wear pattern. I suppose a large degree negative camber would do the same, but that would be noticable by just looking at it.

The reason I ask is because i know that road racers will heat and bend the axle tubes to get some degree of negative camber for handeling.
