Bad vibration 2019 pete 389

If I remember right his only vibrated above 55 mph

 

Peterbuilt HQ has a seismograph like they use for earthquakes. That’s what led them to find that bad driveline.

 

Dealer replaced both my front shafts on my 2019 389 due to bad vibration between 55-65 mph. It's now smooth. Stayed at dealer a month getting fixed. I raised hell about it to the field rep and he extended my warranty an additional year. By the way my truck had 1,000 miles on it. I attached a pic of my truck for the shi* of it.

 

If yours has the spl250 lite series then it's probably the driveshafts like mine. You got to ##### and gripe to your field rep till they replace them like I did,he even extended my warranty an additional year for my trouble.

 

Hi Jake744 I have the same issue you are describing with my 2019 Pete 389 as well I’ve taken it to Peterbilt and they like to blame tires which I know that’s not it, could you possibly send me your VIN # so I can have them look up the notes on yours and compare and maybe just maybe they can get mine fixed same as yours I would greatly appreciate it thank you.

I’d put the truck on jack stands and get a friend to put it through the gears while wheels are off the ground, and get the speedo to where it starts vibrating, Then look around could be warped drum but who knows maybe driveshaft out of balance? Make sure to pick all the rocks out of drives first.
