Its gets regular maintenance.
Just various things are failing. Much of it has failed before and this is its second replacement. Bad design from the factory. Many problems Im having are very common on the ford forums.
This is the second time for fixing leaky exhaust manifolds. I probably should have bought new headers last time, the factory ones are garbage and warp, but it wasnt in the budget. Now its time to pay the piper. Known issue.
This is also the second rear end. First one was near the end of warranty. I think they just rebuilt it with new internals. Who knows if they set it up right? But they are known for eating pinion bearings, and thats what I have to fix now. Known issue.
Driveshaft (rear) is out of balance because ford used a ****** way of mounting the weights to an UNPAINTED! driveshaft. Rust gets behind the weights and pops them off. Another known issue.
Front driveshaft slip is siezed. Driveshaft cant telescope. Im pretty sure the Ujoints are shot too, but cant take driveshaft out to confirm. Will likely have to destroy the driveshaft to get it out.
Bearings in xfer case are in need of replacement. Play on rear output shaft.
Muffler, leaks. This is a normal wear item. Not fords fault.
Rockers etc. They were "repaired" while still under warranty for surface rust. Job was not well done. Now I have to completely replace the rockers. Known issue. Water leaks in the rear 3rd brakelight and takes out the rockers from the inside. Ford didnt seal the light correct.
Drivers seat needs replacement. Leather wore through and tore. Leather was not tough enough.
At least one COP is shot.
Thats about it off the top of my head lol.
And yes it gets lousy mileage on top of all that
