  7. 6.4 Drivetrain Problems
    I have an 08 powerstroke and when I hit a bump or pull into a driveway that has little hump or so it squeaks. This usually happens a lot more when it’s colder outside. Anyone know what this could be and what I could do?

    I have an 08 6.4 Powerstroke and as soon as I accelerate from a complete stop I feel vibration in rear end mainly between first and second gear, also popping noises too. Any ideas of what it could be?

    My 08 6.4 powerstroke started making strange noises. It started out when I was pulling a trailer with a small load on it it sounded like someone running a stick through a chainlink fence making clinging noises. Then when I got home to drop my trailer off the truck barely pulled up the road. As I...

I think I know the obvious but I don’t really want to accept it and am looking for someone who’s gone through this already. I have an 08’ F250 with 230,000 miles. It’s been fantastic so far. I bought it with 180,000...

    I recently ministered my fuel rail pressure on FORscan to try and figure out why I kept going into limp mode. I keep popping p0088 in the PCM so I cleared codes to see my actual fuel rail pressure. I ran the desired side by side with the actual and found they ran mostly hand in hand with few...

    I recently bought a f350 and it's my first diesel so there was some negligence on my part as far as knowing what to look for before buying. It has 90k on it, but it seems the previous owner neglected to drain the water separator regularly. Recently popped the p0088 code, had it diagnosed and...

    I changed the fuel filters in my 6.4 powerstroke today and now the truck will not start. I primed it like I was supposed to and the truck started for 5 seconds and shut off. Now when I turn it over nothing happens. I can hear the fuel pump running and the lights and radio comes on but it just...

    I drive a 2010 6.4 with a dpf+cat delete and an AFE cold air intake. While driving at lower speeds (0-35ish mph) I noticed a loud noise which I can best describe as sound like a jet engine but I never noticed any real difference in power. Which just ended up being a torn air filter. I replaced...

    I have used this forum in the past to help with some 6.0 issues I was having. Unfortunately, I became very familiar with everything involved with the 6.0. Over the 10 years that I owned my f250 with the 6.0, I had my hands on everything from injectors, bullet proofing, HPOP, coolant filter...

    So I'm in the process of replacing my EGR up pipe that was leaking. It's been one problem after another in this process. So far I got all the up pipes unbolted. To do this, I had to remove the transmission and the transfer case. With the up pipes unbolted I can't seem to remove any of them...
