hi i noticed that my 05 f 350 front dif vent tube leaked oil on to my trail arm never done this before can anyone tell me why i never changed the front dif oil so i cant see why this would do this all of a sudden truck was parked on flat drive way should i be concerned thanks

 

In order for that to leak it either had to have been overfilled recently, or it was overheated. If the bearings are starting to go out it could have heated the fluid enough to make it puke oil. Have you had your hubs locked in or been running in 4x4 alot lately?

 

no it was not in 4x4 but i did run the truck on the hi way at a high speed faster than the 65 mph posted i have the truck 3 months and this is the first time this ever happend i think ill call ford to see whats up
