Hello everyone, just thought I would post a little issue I'm having with my F250 here and what is being done. I should preclude all this with the fact that I am entirely happy with my truck and my dealer who has treated me respectfully and been very helpful throughout the process.
My truck is pretty much new, I've only put about 5,000 miles on it in the last 7 months and I bought it new. Just over a month ago while going skiing I was climbing a decent grade at about 45-50mph and the truck was pulling it no problem in 6th gear, around 1k-1.2k rpm. The truck started to shudder or shake similar to the way a car with a manual transmission feels when it's about to stall and you can still save it by pushing in the clutch. There was no chance of it stalling, but the feeling was disconcerting to say the least. It happened a few more times on that climb and I discovered I could stop it by sticking my foot in the throttle and getting the truck to downshift and run a higher rev.
Didn't experience the problem all week and then it happened again going skiing the next weekend, same grade, same spot, same speed. It happened during the week while taking the dirt bikes out with some friends on a road much closer to home. After the 3rd ski strip and wondering what was going on I took it to the shop, no engine codes, just my description. They could not reproduce it, did a software update, gave it back and said see if it does it again.
Well, went skiing again... didn't do it, but it did surge/jerk once right at the top of a steep hill. yay?... sort of... Told the dealer, he closed the ticket, all was back to normal.
I should mention when this event would happen there would be a rubbing and squeaking noise from the car. I figured maybe bushings squeaking when the engine was shaking/shuddering.
Not so fast! Next ski trip it did it again, just like before the update. oh poop. Now I have to take it to the dealer again. This time I did my homework though. I found a grade much closer to the dealer where I could put in in cruise right around 50 mph and reproduce it consistently.
Took the truck the dealer, told him what to do. He did it and it did it. Perfect! They were off to work figuring out what was wrong. It did take them two days, but they determined the turbo vanes were sticking at low rpms causing the waste gate to kick open making the engine surge (that was the rubbing/squeaking sound apparently).
Resolution: new turbo is being installed Monday and we'll get to see if that fixes it. I have 30k more miles on the warranty to see if they did me right with the repair.
I figured this might help someone searching the interwebs for a similar problem.
