I have a vibration around 75-90mph and it's driving me crazy!!! I had it at the driveline shop and they can't figure it out!!! The driveline angles are perfect, the rear driveshaft is balanced perfect with 2 new u joints and the tires are 100% balanced by me and my father as he ownes a tire shop. I'm so stumped!!! It has gotten a bit worse since I installed my BDS traction bars too. I'm starting to think it's a transmission thing. At 75-90 my rearview mirror shakes so much you can't see the car behind you!! Let off on the skinny pedal and it's smooth as glass at any speed, apply some load and here comes the vibration again!!! Any ideas???

My last Dodge gas pot had the same sort of vibration/drone and it was the torque converter. Do you think it would be the torque converter or ant tranny issues???

Thanks for any help or tips...

 

My 04 does the same thing but mine shakes between 65-70. Over 70 or under 65 it is fine. Had dealer check it out and they could not find any thing wrong.

 

Yeah, it's weird!! I'm starting to wonder if it isn't a harmonic balancer thing or something in the tranny??? It's really starting to drive me crazy!!! Such a nice truck with such a terrible vibration.

 

Mine developed this vibration after I had new rear shaft u-joints installed.

Might be worth pulling the shaft, checking the joints and having the shaft rebalanced.

 

could be injectors. hit tow/haul and see if it goes away

 

It does go away by switching it into tow/haul. How does the injectors affect this?? Just that certain RPM in drive it does it. It starts to happen as soon as the truck goes into overdrive. Change the RPM and it goes away but I don't like driving at that kinda RPM all the time.

 

Well Pat's Driveline Red Deer came through for me. They went out of their way because they didn't want to get beat by a Dodge and they built me a completely new driveshaft without the harmonic balancer. My truck is vibration free at ANY speed!!! I have never been so happy since the day I bought this truck!!! Case closed!!!

Thanks to everyone for their suggestions and help.

Well you could say that again

 

wow. could u say it again lol

 

Woah, I don't know what happened there??? Must just be overjoyed!!!

 

I had the 65-70 vibration and I pulled the front driveshaft and it went away. Had the shaft balanced and it almost cured it.

 

same speeds same vibration here too. I was thinking it might be because of mega cab long bed stretch but so far...driveshaft is good, u-joints good...might look at front shaft. does it in oR out of tow haul, kinda got accustomed to it...maybe will leave it as I have grown accustomed to it. kinda use it as a speed governor.
