My 2013 1500 had a vibration around 55-60 mph from day 1, rebalanced and rotated the Goodyears, no help. Replaced the left rear shock, no help. Talked with Chrysler alot so they finally paid to replace tires with Michelin LTX MS2. STILL vibrates, I think I just have to live with it. I really personally believe the driveshaft has a small problem. Has to be that or the rear axle.

 

Had the same thing with my 2011 cc with it being more pronounced on the highway in a slight turn at 60 mph or above...long story short while making a right turn out of a parking lot my right rear wheel broke off right at the at the hub and lodged under the rear end. The axle snapped at the hub. Chrysler honored the 100,000 drive train warranty and now the vibration is gone. Hell of a way to get it fixed.

 

I had problems with both sets of the Wrangler HPs, but so far the Wrangler SRA's are fine.

I've purchased 9 new full size trucks, 5 new full size SUVs (well if you count the Grand Cherokee as full size) and a new Wrangler in my lifetime.


NEVER had a Goodyear or BFG tire come on a vehicle off a lot that was worth a sh*t. Just my experience...

 

So I have a 12 ram sport crew cab and had mine in a lot in the beginning for the vibration just as you describe. I have about 15 different service type visits from various places including the local goodyear tire store, firestone, 3 dealers and an independent alignment suspension shop and all the independents said it was driveshaft related. The dealers all say its normal and no harm will ever come from it! Here is how I reduced mine 90%, I have a dial indicator and a magnetic base from harborfreight, cost was about $40. I attached the base to a stable jackstand under the rear most part of the driveshaft and with the rear of the truck settled on 2 other jackstands I measured the run out at the back of the driveshaft by rotating the driveshaft with the truck in neutral. I wrote the runout on the driveshaft in a blue sharpie marker so if a dealer ever looked under there they would see the amount. I also put a line at the lowest measurement. I went to Lowes and bought a 4" dryer hose clamp for around $4! I installed it so the screw/ heavy part was centered on the low spot. I took the truck for a nice drive on surface streets and the freeway and was happy as could be but there was still a slight vibration that I could tell was not the tires but the driveshaft. Since the truck sits so high I crawled under there and added a nickle by clamping it under the screw part of the hose clamp and took it for another drive, it was a different vibration but it was about the same so I took the nickle out and used a penny and the vibration is 90% gone and I have almost forgotten about it until I read this post! That was almost 2 years ago and so far so good as I haven't had any issues. I will not leave it this way forever as I know it isn't perfect and one day I will have to take the driveshaft off and have it rebuilt so they can take the runout out of it. The runout measured .19 of an inch! Driveshaft is built by Alcoa!!! I saw the sticker on there! I imagine the 10% of vibration I have left is from the crappy tires!!!

 

Update on my vibration issue: After several trips to the dealer on this issue, seems like they finally got about 90% of the vibration out. It seems that the techs they had in the shop Road Force Balancing my tires didn't know what the hell they were doing. They had another more experienced technician balance my tires and 90% of my vibration is gone. Apparently the other techs were not taking all of the old weights off, but adding to the weights already on and had way too much weight on the tires. My tires have very little weight on them now, and almost all vibration is gone. The little that's left probably will not leave until I get rid of these stock tires. I can no longer feel the shake nor can I see my passenger seat shaking or my drink in the drink holder vibrating at any speed. The dealers have the right Road Force Balancing equipment, but I guess not everyone knows how to use it correctly, and these trucks are VERY sensitive to tire bancing issues.

 

The stock tires on your 2012 wouldn't be Wrangler HPs, would it? My 2010 Ram came with them and I had vibration issues with them and I could never seem to find the right tire pressure to get them to wear evenly. I have to say my 2014 came with Wrangler SRAs and they are completely problem free. So far.

Many years ago I worked at an Esso garage. At that time one of the highest rated tires was an Atlas Plycron, which was sold exclusively by Esso (now Exxon). I had four of them on a '59 Chevy (yes, I've made a few errors in judgement over the years) and after about 7000 miles the car developed a very severe vibration. Several attempts at re-balancing only changed the speed or condition at which the problem occurred. Since we couldn't find anything else wrong, I asked one of the older mechanics to take a ride with me to feel the problem. After we got back to the shop I asked him what he thought. He looked at me and said it reminded him of one of his bombing missions over Germany in a B-17 that was "shot up to hell" and shook so bad the waist gunners couldn't take aim at closing German fighters.

Glad to hear that the problem was found.

A more experienced technician... imagine that. Glad you got it fixed.

 

Good deal I'm lucky mine didn't have that.

 

Just be glad these "so-called auto tech`s" aren`t doctor`s or surgeon`s...lol
