Hey, i got my truck back today from the dealership (warranty work) and they "fixed" my head gaskets, rear pinion seal, front/right, back/right, and back/left axle seals. I picked it up after the shop was closed of course and had the joy of driving home with my wheel squealing the whole way home, except when i hit the brakes then the squeal left. I got home and was feeling how hot my brakes were, and on my back/right i couldnt even touch the rim without burning my hand let alone try to touch the brake. Clearly i wont be driving it tomorrow, but anyone know what exactly is wrong? I can get over the half gallon of oil poured over my front bumper, but i would like to keep my wheel/axle in one piece.

Thanks for the help.
