I've been fighting the same thing with my 2012 F150 for 53k miles. I hate the truck so much I can't wait to get back in a CTD. I might have even kept it if it didn't have vibe issues. Three different sets of tires, two sets of rims (plus stock), checked axle runout, driveshaft runout, road force balance on all of em, you name it I've tried it.

The one thing that seems to affect the vibration most is how the wheels are installed. Install with an impact and the vibration is insane. Snug by hand and then torque with a proper torque wrench and it's much better. Only once in the 10 oil changes/rotations I've had done (in addition to all the trips to the tire shop) have I had zero vibration.

And that time the master mechanic at Ford did the install.

I know it's a way different truck, but I have the exact same issue as you.

Bottom line is I'll never purchase a set of Fuel wheels again.

With my 2003 and 2007 CTD's I never had an issue running Weld wheels, Hummer H2 wheels or stock wheels with Toyo tires. All of them balanced perfect and spun true. Smooth as can be at any speed. Only issue I ever had on a CTD was with a bunk set of Cooper mud tires. They were like driving with square tires.

 

I had this once on a set of stock tires. Turns out I had run over a fix in a road and my tires were just junked with tar. Took me a good 2 hours with a screw driver to try to get the tar from the thread. The seat was shaking so bad at that 70 speed mark.

Thankfully that is all it was. I have never had this problem, even with the 35" tires now.

It has to be something with the tires/wheels. Do you have aftermarket wheels? Did whoever install the wheels remove the clips on the front/rear brake hubs before install he wheels?!

I don't think it's anything with the truck. What tires are you running?

 

I have the same problem... the weirdest thing is that when I put the truck in neutral going 70+ MPH its smooth as butter and if I'm in gear (especially accelerating) the cab shakes from side to side...

No idea how to fix it

Worst part is, I'm taking a road trip from Austin to Seattle at the end of the month and I'll be in that shacking range the whole time practically... I need a solution and I need it quick!!!!

Any ideas???

 

You have drive train issues. If by you throwing it in neutral and it alleviates the problem. Some where along the drive train its out of balance. Could be as simple as the drive shaft, see if its missing any balance weights.

 

That's why I hate aftermarket wheels but not saying they are the problem, lug centric wheels will do it. If it goes away in neutral at the same speed you have drive line problems somewhere and I doubt its the wheels. bj or tie rod slop will cause side to side vibes.
Om my old gm half ton I put in readylift 4" and from day one it had a slight vibe and clunck over bumps but couldn't fiqure it out, shop that did the install checked it over and over and retightened everything but it never went away. It wasn't till I went to the dealer that they just lifted it slightly off the ground and put a 7' snipe under the upper bj (new control arms and bj's that came with the kit) that they found a slight slop in the bj.

 

I'm on the stock wheels and running 245/75/17 Kelly Safari TSR's. I'm going to try kicking it into neutral at speed. If it smooths out, I know I can rule out tires.

My 02 F-350 had a vibration issue that we all called "bed hop". Take a look at the tailgate a CC LB Ford around 40 mph and you will see what I'm talking about. There were a lot of smart guys that did a lot of calculations to determine that it was a harmonic issue and that the exact hertz was kicked off somehow at that speed.

Since our vibrations seem to be side to side, I wonder if there isn't a harmonic vibration inherent in these trucks.

 

My dealer basically said the same thing with my truck, it's a frequency/hertz thing at just the right speed. We tried my stock tires/wheels, my aftermarket tires/wheels, tires/wheels off a new 14 in their lot. They hooked up some crazy machine that took readings and my truck had sensors all over it to determine this. They had a ram engineer come in. They basically told me this is the nature of the beast. FML

 

It's unacceptable to be on the freeway and not be able to have a conversation with your passengers without your vocal chords shaking... It's not like we're offroading!!! It's the interstate and its a smooth road but our trucks make them bumpy.

Just one more thing that makes this truck less and less desirable to me.

 

Could it be drivetrain related, driveshaft balance or pinion angle? Does it change when loaded?

 

I'm not sure yet. I got a good deal on the truck so I picked it up, but we aren't planning on buying a trailer until next spring. The most weight the truck has had in the bed has been a few cases of beer.

 

My 12 DRW has done this from day one off the lot. Drives me insane. Air up my bags on the rear and it goes away. I had the driveline rebalanced and they found it too heavy on the slip yolk from the factory. Solved it for a little bit but it's back. I'm considering one of these custom 1pc drivelines since the 2pc is junk on these trucks. I'm at my wits end with it and 3 sets of wheels and tires didn't help.

I just checked under my truck and it seems to be a 1 piece aluminum already so I'm not sure if that will do me much good.

I'm going to load the tongue with 1000lbs this evening and see if it helps.

 

I have been fighting this since mid-August on my 2014 CTD Quad Cab Tradesman. It all started after I was traveling down the highway and hit milled pavement at about 60mph and the truck started doing the "death wobble". Ever since that it has vibrated at 65-up. The dealer initially said there was nothing wrong with the truck, but then agreed to change the steering stabilizer, no help. Then after two dealerships balanced the tires (my dealership only has a spin balance machine) A tire that had been on the front failed the road force balance and had excessive lateral runout. Ram agreed to replace the tires under warrantee but only with OEM Firestones.

My dealer installed the tires and did there spin balance....no help. Next I took it to Firestone at my expense to have a road force balance and to check the front end alignment. They found the tow out, which had been checked and found out by my dealership two weeks before. Firestone also said my dealership hadn't match mounted the tires correctly, but they all had 8-12lbs road force, but the actual balance were all out. Drove it out...still vibrating next day back to Firestone and different tech said that one of the rears was at 50lbs road force and I was all set...still vibrates.

My star case manager called and I was told they wouldn't accept the Firestone work I had paid for and I had to take it to the second dealership for a Ram road force balance. Of course the next day I'm at the dealership and they said that all the tires had to be rotated as they were all out of balance and had excessive road force. Still vibrating, so I put it on the lift myself and as I'm looking around I see three spots where the axle had made contact with the frame during the wobble. The worst was the front differential cover had damage and there was marks on the track bar mount where it hit. I also had a module on the front axle leaking gear lube and an oil leak from somewhere on the front of the motor.

Took it back to my dealer....who said that they would check the axles and driveshafts as well as fix the leaks. Told yesterday that they replaced the leaking module and were going to have Ram replace the dented differential cover but 'inspected' the driveshafts. I had asked the tech last week how he would check them....he told my he would run the truck on the lift and watch them?? This is my third truck since 2001 and I never had a problem with a Ram until now.... Ram is suppose to send a tech at some point... Nobody seems to care at these dealerships and every time the answer is the same, Yep felt the vibration when it came in...fixed now.

 

Jesus man, talk about ruining the new truck buying experience.... Mine's shaking as well, got it balanced yesterday and it's still shaking.

I'm going to run some weight in the back of the bed to see if this driveshaft angle has something to do with it.

 

Im afraid mine is doing this as well noticed it after i rotated my tires myself so im hoping maybe its just the balancing but we will see...

 

If you have vibes at 70 it's the tires or the drivetrain. If it didnt do it when it was new then it's the tires or something bad has happened to the drivetrain. If you think it's in the front (2013) and you've checked everything then pull the front driveshaft. The 2014 front driveshaft does not spin in 2 wheel drive. If you have a 2013 and you want your front driveshaft not to spin, due to a lift, then put some free-spin hubs on it. A lift will bring out the vibes in a drive train. My bet is it's the tires.

 

I had this issue BEFORE I bought my 2014 2500 CTD. They tried to tell me it was the nature of the beast to which I called BS and said lets drive another truck. They swapped wheels and tired and then put 18's on it instead of the 20's and said that it went away and that it was the wheel/truck combination. To which I called BS again. I did some googling and asked them to do a high speed balance and also check the drive shaft - they did the balance and changed the drive shaft and the issue went away. I got all the documentation in case this becomes a repetitive issue - lemon law.

I hope you guys find resolution as the I love the RAM's - I drove 1500's before this one and loved them all - the HEMI was great and the ride was beautiful.

 

So I got my truck back from the dealer this morning and they of course told me that they inspected 'everything' front to back and there was nothing wrong. Took the truck home and put it on the lift and jacked the rear tires to spin the driveshafts. I don't have a runout gauge but put a square clamped so it wouldn't move. I saw about an 1/8 of an inch of runout on the front driveshaft. Dealership couldn't care, they told me that they had told Ram there was no problems with the truck and they couldn't detect a vibration. Even with a video I took of the driveshaft.

 

Have you tried to find a new dealer to do your warrant work?

 

just bought 2014 dually as did my friend, called him the other week going down the road and the passenger seat just rocking side to side. I had tires changed to the 255's so thought it could be balance problem. he has the same issue and trucks have under 1000 ,iles on them as we both have other vehicles. dealer said bring them in.

 

let me know if you come up with a solution. I put a load on a trailer yesterday to squat the back to see if it was the angle of the driveshaft but hard to tell as the truck still shakes but differently since there's a trailer hooked up and I can't tell if it's the trailer that's causing the shaking or if it's the same problem I was having while unloaded.

 

Update: I got my truck back from the dealership who had promised to check the driveshafts, bearings and pinion angles. Asked them when I picked it up if anything had been found and they told me they "checked everything front to back nothing wrong" Got the truck on the highway of course it was vibrating still so I took it home put it on the four post lift and jacked the tires off the lift to spin the driveshafts. I do not have a runout gauge, but I mounted a square on the lift and clamped it in place. Hard to tell on the rear drive shaft as it was close, but on the front there was about an 1/8 of an inch runout by this method. Went back to the dealership and asked what they had found and they told me that they hadn't checked it. I told them that's why I brought the truck back for the 8th time and the service manager told me they wouldn't check anything Chrysler wouldn't authorize and that he had told them he test drove the truck and there was no highway vibration in his opinion.

Took the video to a driveshaft shop and they said of course my way of checking the runout was like...."a monkey f'ing a football" but that it looked like I had excessive runout. Spoke with the owner of the dealership and they put their hands in the air. FYI during the trip today I had 600 pounds in the bed to see if that helped and no luck. Out of options....

 

And I forgot. The driveshaft shop recommended taking the front shaft off and driving the truck if the vibration ended bring the front drive shaft in and they would check it, if it was bad they would provide me documentation to give to the dealership. If it continued with the front shaft removed I should bring them both in and they would do the same...

Dealership told me if I pulled the driveshafts my claim was over.... Even though they have told Chrysler I have no problem and they will not service the truck

 

Total BS.

How can some have perfectly smooth trucks and then others (you and me) have this vibration that no one can figure out??!?! I'll go mad

 

Anyone have any experience with driveshaft runout want to let me know what they think? It's hard to see but I had about an 1/8 of an inch clearance on the square as I rotated the axle by hand.

I do think mine started with the wobble, but the driveshaft shop that I talked to today told me that Ram changed driveshaft manufacturers and now there is a harmonic balancer on the rear drive shaft. He told me that he has worked on over a half dozen new trucks and the first thing he did was to remove the harmonic balancer which can come loose and move around. I have no knowledge about the balancer that's just what he said. He told me that the trucks in the past didn't have the balancer and its been a problem. Might be worth looking into

 

This is why E mail is such a beautiful thing. It never goes away, can be re-sent and documented that it was opened. Phone conversations and face to face is your word against his. video can be attached and sent to Ram HQ. There are ways to beat the dealer.

 

2013 Ram 3500 Dually Shakes - YouTube

Took the video this morning.

This truck is absolutely no fun to drive anymore. The vibrations are so intense that my pregnant wife can't ride in the truck anymore without getting sick.

 

i noticed 90% of the shaking trucks have AISIN's...

 

I have no issue with my truck. How about opening a 'Lemon Law' case? Might just get some action.

 

I have retained an attorney and started the lemon law process. Last week the truck was at the dealership and I had to leave the truck there for two more days to have a road force balance. (that makes the total 46 days) Went back to the dealership and told the service manager I wanted a copy of the road force balance numbers they were reporting to Ram. They handed me the invoice from another dealership that had four numbers on the paper and I told the service manager they couldn't be road force numbers as they were decimals and the road force values would be in lbs. The manager said "those are the numbers" turned his back and walked away.

I drove to the facility where my dealer had to take the truck and it was confirmed, the service manager had asked them for the 'runout' numbers and not the road force values. So who knows what is going on with my case. I reached out to the owner of the dealership and no contact yet. Seems that the dealership answer is to stick to the story there is no vibration and ignore my requests to have the drive shafts inspected. Even my Star Case Manager will not return my telephone calls....

 

Give me the name and address to the dealership, PM me your full name and VIN

I'll handle this one
