Oh, the guys who do the coding were. The guys out in the shop, not so much... Quote Link to comment Share on other sites More sharing options...
theoldwizard Posted May 6, 2019 Share Posted May 6, 2019 Interesting that BOTH the front an rear joints failed. One was the cross in a U-joint. No failure on the higher powered 3.5L EcoBoost. I winder what the difference is in the drivetrain ? Quote Link to comment Share on other sites More sharing options...
92merc Posted May 6, 2019 Share Posted May 6, 2019 I wonder if the back part failed, then the front kept spinning a bit and tore the front part off. Quote Link to comment Share on other sites More sharing options...

I actually didn't watch the whole video. So I'm not sure which was first. Quote Link to comment Share on other sites More sharing options...

jcartwright99 Posted May 6, 2019 Share Posted May 6, 2019 I think these guys are good entertainment. I usually watch their ridiculousness on my commute to work. Don't worry, I am on a train. 1 1 Quote Link to comment Share on other sites More sharing options...

theoldwizard Posted May 7, 2019 Share Posted May 7, 2019 Back in the early 90s. I worked just down the hall from the guys doing the the development on the 7.3L PowerStroke diesel. One of theit test vehicles was an F350 dually with a manual transmission. One of their unofficial tests was to loaf the truck up to max GVW, place the transmission in 1st gear, rev to about 2000 RPM and side steep the clutch. Either the tires broke loose or something broke. Walking by one guys desk one day, I noticed a big chunk of steel on his desk. It was a piece of the driveshaft with a 90+° twist in it ! They had already blown multiple u-joints, clutches and even a few transmission input shafts ! 1 Quote Link to comment Share on other sites More sharing options...
