Sorry, I just don't see how the f-150 trans could cause any problems with the front wishbone. Never even heard of any problems before your mentioning it.
Close to 15K miles on mine, less on my Dad's but enough that if there were problems they would have shown up by now. ( motors are not stock and NOT driven like a stocker)
Would love to see more on your club member's failure and this so-called "beefed-up" unit, whatever that may be ?
Sounds more like a Mitchel O/D lover trying to spread bad rumors
