Ford Super Duty (1999-2016) :: 2008 F250 - Sudden Loss Of Power

On the highway doing 100 mph. during af take over, my Ford F-250 6,4 Super Duty 2008, lost nearly all power. (now it is like driving my old hummer h1)
Engine and car runs/starts great, only 10 minutes uptil 60 mph. now.

My mechanic has given up. He checked following:

EGR = OK
HOSES = OK
ERROR CODES = NONE
INTER COOLER = OK
PARTICLE FILTER CLEAN = OK
TEST WITHOUT EXHAUST = NO DIFFERENCE
FLUIDS = OK

Hopefully something I can fix with my hammer. The car has 85.000 miles on the clock.

I'm wanting to swap the 5 4 for a 6.0. Reason I saw 6.0 is my buddy's done egr delete. Bulletproof oil cooler head studs and a edge with attitude chip and has great power and reasonable fuel mileage. How hard is it going to be swapping the motors.

Ford Super Duty (1999-2016) :: 2008 F250 Wants To Go Into 4wd All By Itself

Seems recently my 2008 f250 diesel wants to go into 4wd all by itself. It's the electric switch on dash with the auto/lock front hubs. I'm thinking either the dash switch or the accuator motor. Where to start though... Also I can turn the switch to 4 wheel high and it doesn't go in.

Ford Super Duty (1999-2016) :: 2008 F250 - Tailgate Won't Latch

I have a 2008 F250 that the tailgate has always been real easy to open and close until the other day I could not get it to latch so i slammed it and it did latch and it worked a few days but now it won't latch at all. I can open and close the latch with the tailgate down but nothing I do will make it latch in place. I've tried spraying with PB blaster it didn't work. Not sure if its out of adjustment or what.

Ford Super Duty (1999-2016) :: 2008 F250 - Stuck In Park

My Ford 250 is currently stuck in park, it starts but I can't move the shifter. It sounds like it is a fuse issue from what I have read, but I bought the truck at an auction and I don't have a book. Do the brake or parking brake fuse? And where is it located? I know there is a panel under the hood and under the dash, which fuse to look for. It's a 2008 extended cab gas model.

How to disassemble the dashboard on my 2008 F250 FX4? I removed the few screws I could find. But most of the panels seems to be stuck behind the central panel (where the radio and A/C controls are). For the life of me I can't figure how to take it apart.

Ford Super Duty (1999-2016) :: 2008 F250 - Brakes Going To Floor

I believe my brakes have a problem.

Lately, I can stomp on my brakes @ 50 mph and they won't trigger the abs or come close to skidding the tires. The peddle goes to the floor if I push hard enough and the truck doesn't seem to stop fast like it used to.

I'm wondering if there is an issue I should be focusing on, like swelling brake lines or some issue you may know of. I'll try bleeding the brakes this coming weekend, but i think its going to be a bad brake line or something.

Ford Super Duty (1999-2016) :: 2008 F250 - Very Rough Ride

My 2008 F250 Super Duty is riding very, very rough. I put in new heavy duty Bilstien shocks 2 or 3 years ago, and I would think they would last longer than this.

Are they any other causes I can look at to see what is causing this truck to ride rough?

Ford Super Duty (1999-2016) :: 2008 F250 4X4 Not Working All The Time

I have a 2008 Ford F250 with 6.4. Having alot of problems with the 4X4. Went to put the truck in 4 wheel drive one day and noticed the light on the dash never came on to engage 4X4. Of course we had a big snow storm coming and I didn't have 4 wheel drive. I drove the truck across town and decided to just try 4x4 again and it worked that time. I got the light on the dash and could hear the transfer case shift motor engage. Came out a little later and tried it and it wasn't working again. Took truck to shop where they replaced transfer case shift motor with a remaned motor from oriellys.

4x4 worked for a few weeks then just started doing the same thing again. We thought maybe that motor had problems also so had it replaced too. Truck is still doing the same stuff. Sometimes it works sometimes it doesn't. Figured out that if its not working and I leave it in 4x4 and unhook power to shift motor then plug it back in it will engage 4x4. I've seen some post on here but sounds like everyone i've seen their motor just stops and doesn't work at all.
