Is the frequency (pitch) of the vibration constant, or does it vary with speed while you are turning?
For me it was a constant vibration. Once it started it would continue for another 15 to 30 degree rotation of the steering wheel. Only last maybe 2-3 seconds. Imagine your steering wheel having the same vibration setting as your phone for 2 to 3 seconds.Is the frequency (pitch) of the vibration constant, or does it vary with speed while you are turning?
This is not a buzz, but a low pitched grinding sound like 2 things rubbing together hard.Have you compared the vibration /noise to the sound of the antilock brake pump cycling? When I went through all my problems with the antilock pump system (related to faults in the wheel speed sensors) I triggered it lots of times and became quite familiar with the sound of the pump firing without it actually applying the brakes. Have you noticed if your traction control light momentarily blinks when you hear the noise.
The pump makes a constant high speed buzz that does not vary with speed.
Sharp turns have the wheels turning at markedly different speeds. One wheel speed sensor may be marginally installed, have a wiring issue or the system may have a fault.
I had the rack replaced 4k miles ago. The vibration/grinding was gone. Unfortunately, it has come back on right hand turns. Same vibration.
It happens without the brakes applied, and while accelerating when it gets really bad.Have you compared the vibration /noise to the sound of the antilock brake pump cycling?
Me too I felt it a week ago, just had my rack replaced 2 months ago.that's really disappointing. I was hoping it was the rack and an easy fix.
The ABS pump is used as part of the traction control system. The TCS applies braking to individual wheels when it detects wheel slippage independent of your brake pedal input in an attempt to reduce what it thinks is wheel spin. If a portion of TCS is misbehaving (most often a wheel sensor) it drives the ABS pump in short cycles.It happens without the brakes applied, and while accelerating when it gets really bad.
Any luck?So theoretically turning off the TCS should stop this from happening assuming that’s the issue?
I’m going to try it tomorrow morning and see if that does anything.
Honestly the problem stopped randomly and hasn’t been making the noise ever since. I have no idea what caused it to stop.Any luck?
Posted this in the 2 other forum threads talking about this. I was seeing a lot of the same issues being described in this thread:
Wanted to wait a couple days before posting an update but this looks to be fixed for me. Ultimately it was a differential fluid issue, which is one of the shared fixes across the threads in this subject. I have the 3.92 rear end with LSD. What I’m struggling with is how difficult this has been to diagnose by the respective dealers. Dealer #2 was much better at diagnosis, listening and ultimately solving the problem. I equate it to just seeing more vehicles and having more tenured staff and mechanics than the 1st dealer. Tracing this all the way back I had zero issues for the first 16k miles or so. Towed a boat and launched and recovered at a very shallow ramp which had the rear end submerged for >5-10 mins. They shared that this was a potential introduction of moisture to the fluid, which makes sense cause I had the issue for the subsequent 3k miles and upon seeing the fluid they said it had bubbles in it but was not milky at all. You drive so often you become numb to changes over time but I can tell you this has also fixed the surging when letting off the brake or restarting from stop/start and the truck is more stable when crossing expansion areas on the highway like bridge transitions. They also suggested doing the rear differential fluid service every 30k miles anyway having seen other issues, especially those that tow more. Hoping this helps others experiencing the issue.

This seems impossible, but I had the same experience. My grinding got worse and worse the lower my oe 22 inch tires got. I had grinding with right and left turns and at the end I could get it to grind for 10 seconds under the right conditions. My tires were like 3-4/32. The second I put on new Cooper tires, it felt like I was driving on glass. So much smoother even without turning. I've been driving for a week and haven't had a single grind (and I've been trying).POSSIBLE FIX TO PROBLEM
I've had the exact same issue since 10k miles, and currently have 34k. The dealer said RAM is aware of the issue, but there currently is no fix. It actually got embarrassing to have someone ride with me and ask what that noise was every time I turned right.
So here's the interesting thing. The factory Good Year tires are horrible, and I think most people on here have recognized that. I've been waiting as long as possible prior to winter for replacement, but I literally had zero tread in the center of two of them and needed new ones now. My tires are rotated every 5k, and they are not overinflated. Yesterday I had Discount Tire install a new set of Cooper Discoverer AT3 4S tires (285/45R22). As soon as I drove away and made my first right turn, I knew the problem was the tires...the noise was gone! The true test was coming to work this morning and driving through the parking ramp. This is where the noise (and grinding sensation) was the worst. There was zero noise from every turn I made.
Hopefully this helps and is the same problem others are having. I know at least one other person wrote about the noise going away after having the tires changed.
Good Luck!
I think I'm going to change my rear differential fluid and give it a shot. I'm glad that you mentioned the boat launch because mine did start doing this after I started going to a new boat launch that requires me to submerge the rear axle in order to float the boat. It makes sense to me. I know some people were saying that its the steering; but I swear that I'm feeling it from the rear.Posted this in the 2 other forum threads talking about this.

Turned off my TCS today and did not have a shudder/grind turning right. I'm going to keep checking. I will include this the next time I take it in (I've got two FCA recalls in my mail stack).
