Engine hasn’t be overhauled and operating strong, no oil consumption.

Ubolts on the front axle were both replaced last year.


Have all you guy deleted your egr or are you running it like it came from factory?

I need to change the harmonic balancer for the crank still

Bought the new truck in 2013 so nothing else was done and only had one driver

The shaking happens every trip but sometimes and after resetting the Jakes it goes away

If that is all you have done to that truck, and it is still running down the road with the emissions intact, you are one lucky dude, LOL! I would at least do a proper EGR tuneup and change out the dosers. Has the SCR system along with the DPF system been regularly serviced? I would also open the top of the motor to inspect the cam shaft, I can only imagine what that may look like...
