2005 break/rotor / front axle problems?

[6LPSD]

hey guys my 05 f250 4x4 dsl is giving me problems, took it to the delaer, there was a leaking coming from the front left axle tube, they fixed it, the axle tube seal was leaking, and the left diff carrier berings were pitted also all replaced under my extended warrenty, it also has a weid break squeeling problem the breaks dont squeel when the truck is first started up and ran for about 5 mi but happens about 10-15 min down the road, the front left is the worst everytime i go to a stop light or sign it squeels when i put on the breaks and and pull out again it seems to be worse on the left side when i go for a left turn since i can here it better on that side. does anybody know that if their is a general fix/defect problem for this problem also the axle tube problem since this truck is a first 2005 run type and not built after 12.04 was built in 11.04?
thanks for the help.
