I drive a 2009 Dodge Ram 1500 4x4 5.7L Hemi
Earlier this week I noticed that my truck would start to vibrate as soon as I got to 20mph and would get worse when I would get to 40mph But!! It will mellow out on the highway around 60 to 70mph as far as vibration... but you can still feel the smallest vibration going on. And when I decelerate on its own without applying brakes as soon as it drops to 50mph its vibrating everything.
The vibration is really bad it shakes the whole truck and it is so bad that when I get home my hands are still tingly from the vibration..
At first Im thought it was the Brake rotors because a few years ago when I changed my pads the rotors looked warped but I didn't change them (The Rotors).
Now I noticed that low speeds like 10mph. I can feel and hear a little bit of a grinding or rubbing noise coming from the front center area underneath the truck.
I went to one mechanic but they told me that I needed to change the whole REAR differential. Which kind of seemed weird but I am open ears.
If anybody can help me out! Let me know what I should look for or what I can do to test somethings out. That would be awesome. And ill answer any other questions if there is something I missed. Thank you

Does the vibration change if you lightly apply the brakes? How about if you carefully shift to neutral?
If it doesn't change if you lightly apply the brakes while still in the vibration speed zone, I think you can shift any focus away from brake rotors as the cause of this vibration. A driveshaft/u-joint seems like a very good suspicion. If you're handy with tools you can probably pull the driveshaft to manually inspect for a dry joint. It may also be worth your effort to check the condition of the fluid in the rear differential and transfer case. I'm not sure if your 2009 has a carrier bearing along the drive shaft, but if so, check that while the driveshaft is out. Also check the condition of the transmission/transfer case mounting points for worn or damaged isolators.

Right so the vibration doesn't change when I apply the brakes or when I switch it to neutral. And yes I will check to see if I see any wear. I haven't changed the differential fluid actually now that I think about it and since I've had the truck I've gone maybe 30k miles so far so ill check that as well.

Right I'm going to check those right now and see if there all in place correctly.
