I purchased a new 2021 Ram 1500 Big Horn Night Edition near the end of July. It is a very sharp truck. I’ve done quiet a bit. I’ve had a bed liner sprayed in, tinted the windows, Added aeroskin hood deflector and window visors, had new heavy duty tires put on , and added air lift air bags to the rear. Shortly after buying it I begin to notice a slight vibration in the area of 2000 RPMs and 50- 57 mph. It sounds rhythmic and like it is turning. Kind of like a hum /vibration but can feel it in steering wheel too. I have read the post on MDS, Eco, and ANC. I bought a bypass harness for the ANC. Actually 2. One was Idatalink and the other was pac. The pac plugs back into the anc module. No improvement. The idatalink seems like it helps some. It does not plug back into module. Anyway the vibration/ hum continues. Sometimes worse than others. It is almost like something overtorquing or maybe some kind of a compression issue in the exhaust. I thought maybe it was a breakin thing so I decided to put 1000 miles on it to see if it went away. It’s one of those things that in any other vehicle I would say there is something wrong with it. In this Ram based on what I’ve read I am betwixt it being normal or something wrong. At any rate it is beginning to frustrate me. The more post I read the more hopeless and frustrated I become. If using the gear limiter/ tow haul button, and bypass harness does not work does anyone have any ideas what this is? Thanks for any and all help.
