i have a 2009 dodge ram 2500 HEMI 4x4 140kmiles even tho its a 09 its the 08 body style ever since i got it i have had a driveline vibration when you go 40 you can feel it in wheel/seats then it goes away until you hit 60 its really bad whole truck vibrates i use to have the death wobble but i fixed that and now this......... Things i have replaced, Every single ujoint on the truck, 2 new front hubs, upper and lower ball joints, Tires where balanced today no change not worse not better... what else could it be? could a transfer case cause this? mine leaks but i keep it full with atf+4 only other thing i can think of is the rear driveshaft is bent or something? even tho it looks fine even if it is bad why would i feel it in the wheel aswell?.

Any suggestions i am at a loss i need help to much money put into this thing to dump it.

 

Any open recalls on your truck? Wasn't there one about the rear pinion nut??

What about the tires? Does rotating them make any difference? Do you feel it thru the steering? Or the seat??

 

Didnt see any recalls besides airbags and those where done and yes i rotated tires no diffrence they are brand new aswell and yes i do feel it in the seat and wheel i cant tell if its from the rear or the front almost like the middle of the truck. also forgot to mention i took front driveshaft out so that wasn't it.

 

Any pulsation from the brake pedal when you gently apply them?

 

No pulsation breaks are good all new rotors and pads i have wasted so much money on changing parts its getting to be nutz. u feel it around 40 then its not so bad til u hit 60 60+the truck viberates like crazy i feel it in the wheel seats floors ect.

Also now that you brought it up i will check pinion nut any ways i have nothing to loose at this point lol

 

I might be tempted to have the rear driveshaft rebalanced..... Its got to be something that's rotating that is out of balance, and since the tires are new, and you already checked those......

 

Take a look at your engine mounts.
You mention that your vibration comes and goes at certain speeds. From the FSM:
"Propeller shaft vibration increases with vehicle speed. A vibration that occurs at a specific speed range, is not usually caused by an out of balance propeller shaft. Defective universal joints or an incorrect propeller shaft angle are usually the cause of such a vibration."

Hope this helps.

 

I will check motor mounts next and it comes and goes but 60+ it never goes away sometimes you feel it at lower speeds sometimes the truck is lifted but factory lifted it came this way is it possible for a transfer case to cause vibration? i know at some point someone rebuilt it in 2016 before i got it and now it leaks. I might still have the rear driveshaft checked out

 

Check driveline angles as well.
