When the vibration is occurring at its worst. If you swerve aggressive but safe does it have any effect?

If you remove the rear driveshaft and run the vehicle in 4 high with the front axle pulling the vehicle, does this make a difference?

I assumed that would be the case and that is okay.

Chris, Didn't have a chance to check those items yet, weather related delays, do have a question regarding Ford TSB's
Shudder or Vibration on acceleration TSB 09-20-5 this applies to 2008-2010 F-250, F-350. This article supersedes TSB 9-4-9 to up date vehicle model years. Can you get a copy of TSB 9-4-9 I'd like to know if it applies to my year truck. if so can you send me a copy? My truck is going to the dealer on Monday 15 Jan 2018 for this problem and other work thank you again.

Once a TSB is superseded, that TSB is no longer available. Here is the TSB https://www.dropbox.com/s/lc6szhjp6llx6y8/92015.pdf?dl=0

This TSB does not apply to your year model.

Now that I have posted a partial or complete answer, you will see you can rate me. The deposit you have already paid is not transferred to me until you rate me. I would like to receive nothing less than 5-star excellent ratings. So if we are not there yet, please reply and let me help more. If you're not pleased, let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent replying. Thanks Chris

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
