Cummins hopping!!! need help!!
 

I have an 07 cummins and love it but, whenever you hit a bump around 70mph it starts to hop. it hops so bad that it throws cups out of my cup holder. any ideas on how to stop it?

Is it more of an up and down, or does the truck shake back and forth?? If back and forth, it's what they call death wobble. Need to replace pretty much most of the front end.

There is a TSB out to fix/upgrade the steering to the tie rod drag link style VS. the current inverted y.

lol There is ALSO a TSB out to fix some of the replacement steering upgrades!

:pca1:

mine did that, replaced shocks first,,still the same, then track bar and tie rods still the same, put on different tires, wahlah, fixed

Yeah, sounds like the track bar. My 03 did the same thing. Turns out the rubber bushing on the track bar was worn out. You can get the bushing at NAPA for $13. Easy fix. Just curious, shouldnt it still be under warranty?

Any updates??

Any luck??

Does the truck have a lift kit I know there were some issues with kits. If not let us know what you fine out
