First time caller here.... about 2 months ago I purchased a "certified pre owned" 2022 ram 1500 classic 2wd crew cab with the 3.6, 850re transmission and 38,000 miles on the odometer.
Just a few days after closing the deal, I noticed a strange vibration on deceleration between approximately 40 and 20 miles per hour that feels somewhat like running over the rumble strip on the side of the road and a constant, slightly less noticeable vibration cruising at around 55. It's a fast vibration that is felt in the seat, not the steering wheel which leads me to assume that it's driveline related and occurs both during braking and coasting without any brake application. The vibration goes away when the transmission is put into neutral and is not present during acceleration.
So far I've made 4 trips to the dealers service department to try to get the issue resolved with no real improvement.
Trip#1- they visually inspected the driveshaft and carrier bearing but did not find a smoking gun. They roadforce balanced all 4 tires to find that the right rear was defective. (The dealership put 4 brand new Goodyear sra tires on it before the sale) they had to order a new tire and said to come back at a later date for installation.
Trip#2- new tire was mounted, balanced and installed. I noticed no improvement in the vibration on the trip home
Trip#3- the transmission control module was re flashed and the tech said it was good to go. Again, the vibration was still there on the trip home
Trip#4- a star case was opened with chrysler, chrysler had them install a new valve body in the transmission which did not fix the vibration, which led them to replacing the entire transmission, torque converter and transmission cooler...... the vibration was still there on the trip home.
I have no hard feelings towards the dealership, I feel like they are doing what that can to work with chrysler's warranty process and try to come to a solution but I'm about to bring it back for trip number 5 and they have had the truck more than I have in my 2 months of ownership. So far I'm struggling to keep my hands off for warranty purposes but have slid under the truck to put my eyes on everything. There's no powdery rust on any u joints or slack that would indicate a bad u joint, Carrier bearing looks and rotates fine, there does not appear to be any balance weights missing, no loose hardware on the yokes, no slack in the pinion bearing. I'm at a loss here, has anyone had any experience with bad bushings on The rear suspension links causing a bad pinion angle or something similar? 38,000 miles doesn't seem like enough wear and tear to be having this sort of problem and the bottom of the truck is clean and shows no obvious signs of abuse. Does anyone have any experience with a similar situation and know of a fix?
