    I was a Ford shop foreman 10years that was enough Ford but an engineer did show me an easy driveshaft balance with a hose clamp on the shaft but not completely tightened, Jack stands under rear axle, someone in the truck running the speed to optimize the vibration. A second person with a piece of heater hose taps the clamp until the driver beeps the horn when the vibration is gone. This an approved repair.

    I would just like to take a second to say you are completely awesome, thank you for video, my vacuum line was broken and now me and my wife can go and play in the snow with our 4x4. Thanks

  • @halleffect1
    i learn something new every time i watch an EricO vid. i would have never thought to use a smoke machine to test for a leaky seal.
  • @CopCat34
    Great video. Thanks for showing all of the steps. I really appreciate you showing when you temporarily forgot to check the other side for a vacuum leak. Makes the video stick in your mind. Thanks again.
  • @livalittle100
    Eric, your'e amazing! Thanks for the videos. Just wanted you to know how much we appreciate what you do.
  • @nikefutbol13
    I've been watching your videos for a long time now and I never realized you are so close! We're right in Bloomfield. I'm definitely going to keep you in mind.
  • Man I want to say thanks. You answered all my questions in one video that I couldn't find in 4 other videos. Very detailed and all the proper zooms in needed. Thanks man
  • I've done those a few times and installing that seal without the tool isn't fun and even with it you need to just take your time hats off too you Eric you make my days so much more interesting and look forward to what's in store for me everyday. Keep wrenching my friend
  • @matthewyates3230
    I have watched plenty of videos on the wheel hub and bearing assemblies. Your video is so in depth and explained so well in detail, I can just about picture and understand all the working parts of the assemblies by memory alone now. Great video. thank you
  • @crjcwoods
    Thank you for this insight. We have this same truck, but a 99 with 420,000 miles on it and you led me to the broken vacuum line at the hubs, fixed and they work like they should. Five minute fix. Awesome!
  • @arthouston7361
    This is a good lesson for every tech to stop, step back, and review everything before you commit to a completed diagnosis.
  • Excellent videos on the F250, all the way from start to finish on ball joints, axle seal replacement and tie rod ends. Appreciate the detailed info on tools required for the job! Nothing worse than getting into a repair and not having what you need. Did need to cut a couple pieces of three inch pipe for the ball joint install, tool from HF didn't come with all the sizes but still worth $100
  • @pskauto6798
    Nice video Eric , love watching them as shop owner , a tech , fellow YouTuber, AND A subscriber
  • @Nymi5
    Great video again ! I am parts guy here in Finland, I sell US car parts (GM, Mopar Ford+Speed parts)here in Finland and this video was really helpful to me because now i understand how that system really works and what are the weak points. So it's easier me to sell right parts to customer. Thank´s again !
  • @batard
    Love these videos, Eric. I'm looking forward to more in the near future.
  • @baxrok2.
    Good stuff Eric. I attempted to help my nephew troubleshoot the vacuum hubs on his Ford truck over the phone a couple of years ago. Now I see why it was such an epic fail! Thanks for showing us how it's done!
