Vibrations Baby!

[SargeFirstClass]

Im sure this will get relocated to a different thread, but has anybody figured out this goofy random vibration issue or where it comes from? Ive tried different sets and types of tires, different wheels, front leveling kit in, and then back out and then back in again, visually checking every dang piece of drive train and I cannot figure it out. Some speeds it is there, then sometimes it isnt at all, but it is always there past 65mph. I feel it mainly in the seat and the floor, never in the steering wheel but since it is rack and pinion type I may not feel it there when it really is. I am completely dumbfounded buy this! HELP!!!!!!!!!!!

Oh, and yes I have had every set of tires I tried road force balanced.

Wonder if it could have anything to do with the rear transmission mount or a pinion issue or a driveshaft issue. Its a 2016 RAM 1500 Tradesman 4x4 5.7 hemi regular cab long bed, you know, a work truck!

Did it just start or has it always been there?

It wasn't there when I first bought the truck in 2016 but soon after that I think it started vibrating. I did put a set of fierce attitude tires on 18x9 wheels right after I got it and there was no vibration. After I got new tires and wheels (the first time) it started. I put the original tires and wheels back on just for a test and the vibration was still there. I've tried everything from A/T 275's to the current M/T 35's 18" wheels to 17" wheels, and the list goes on...........

Years ago chased a seat vibration for a couple months on a 96 f150. Decided to sell it, when the buyer got there he waited till I signed over the title then dipped down under the truck and popped back up in less then 5 secs and said it was the trans (or transfer case dont remember) mount. I looked and sure enough it was loose. He got a good deal btw

A vibration in the seat of your pants usually indicates something in the rear of the truck is not happy, such as a crossmember mount, u-joint or even something as simple as a warped rotor. I would start by inspecting your rotors if you have a lot of miles on them chances are they maybe warped and the cause of your issues since you have had the vibration with multiple different sets of tires. If the rotors check out good then move inward and forward up the drivetrain. Another option is if you have a go-pro you can use that as a diagnostic tool moving it around and looking and various components at the vibration speed that would otherwise be impossible to inspect.

Rear shocks, OEM shocks suck. On my 2015 that I got used they were blown @ 50k and were caked with dirt build up from being driven on dirt roads.

Did you try Michelin Defender LTX tires? I've found over the last ten years that the stock Goodyear tires are the culprit and the Micheline Defenders make it ride and drive like a totally different truck.
