2015 6.7 skiping

[chris dunkin]

I have a 250 2015 that seams to clunk as I drive at any speed feels like it is shutting of and coming back on in 1 second or that it comes out of gear and clunks back in. But it is not the trans. I believe it is electric. I have hade to the dealer for 3 yes 3 weeks going on 4 they have no clue. any ideas?

That's not really a lot of info to go off of. Any codes? When you say it clunks does the dash go dead?

Hi the truck feels like the rear end is going to come out from under it at high speeds at low speed it's just a small jerk the dealership thanks it is an electric problem and it is random any speed the electric on the dash stays on the only saying I have seen on the dash where it gives you the miles per gallon when it does the skipping or clunking the miles per gallon in Decatur will Spike up and drop right back down the skip are funk only last for a split second and it does not put out a code I rode around with a code reader on it for 2 weeks and never picked up a code when it does be jerking any advice would be a help thank you

FICM? I went through this on my 6.0 recently and FICM was it.

I just had the same problem on my 2016 f-250. I found my rear u-joint to be tight. So far so good for me but it’s only been 2 days. Seems like there’s lots of issues on this matter.

Never mind it’s back. Feels like a very Bulged tire.

So little update. I’ve replaced the the rear u joint, all 4 ranch shocks which where dead and needed to be replaced. All that seemed to help very little. I had all 4 tires road force balance which and cleaned all hub surfaces very well. I still have slight vibration or hopping feeling but it goes away. My next step is to have another exhaust hanger welded on to the straight pipe because it only has 1 on it. I don’t buy this talk about the frame twisting as you driving.

Rear U-joint?
