I have a 05 Ford F150 and my differential has gone out and needs to be rebuilt I had this issue while under warranty but Ford always found excuses and now that its out of warranty I started to research and I have found alot of complaints where people complain of loud noise and vibrations at the above speeds of 45mph.

Driving on road in school zone (25 miles per hour) children playing on sidewalk. Children were jumping on off sidewalk into street. Applied my brakes. Heard clunk in the back of the truck then - no brake. Used emergency brake to stop. Failure occurred as axle broke, apparently loose for long time - not original owner, purchased from dealer. C clamp holding axle in place is dissolved into small pieces causing axel to come out. Caliper is toast (only thing holding axle into place) rotor, brake pad, all rear axle components - completely failed, caused over $3,000 in repairs to truck. Extended warranty won't cover stating when the tire rubbed against the curb - they consider that as impact - Ford wants no part in fixing - said no reported problems with C-clamp (no recalls) or axel breaking or slipping away. A true nightmare! - you pay for extended warranty - but they don't pay for the repair, you buy a truck from a dealer, yet they don't check safety - only tires, wipers and small stuff. Consumer is forced to bear any defective parts on their own. Really frustrated.

While driving on highway @ 60mph, my 4 wheel drive activated without my touching the dash control. The front axle made terrible grinding noises and the vehicle slowed dramatically. Dealer told me it was a vacuum line and Ford replaced under warranty.
