i just bought a new 2015 Ram 1500 diesel. It seems to have a vibration at highway speeds. Not severe but noticeable. Has anyone else experienced this? Looking on one of the forums I see something about a pinion nut. Any help or insight is appreciated.

Unfortunately I can't offer much on this except that a few years ago I was going to purchase a new 2010 Laramie and backed out of the deal after I drove the truck home and had a highway vibration the entire 100 mile round trap back and forth to the dealer. From what I read at the time the trucks were having issues with flat spots on the tires as well as getting the chrome clad wheels balanced correctly. My 2014 Ecodiesel has had no issues with vibrations at all.

I'd recommend you take it back to the dealer and have them go through it.

I have that also on my 2014. I almost feels like a tire issue, but it goes away when increasing or decreasing throttle. That makes me believe its either engine or transmission. Of course, the dealers all say nothing is wrong...

There is a recall/TSB for head replacements on some ecodiesels for a shimmy that feels like a suspension/tire issue. I've not heard of anyone actually qualifying/getting it done though.

New Ram 1500 Eco Diesel 3.0L Turbocharged

I recently purchased a new 2015 Ram 1500 quad cab 4x4 EcoDiesel 3.0L Turbocharged truck.

At highway speed at 65mph and above a slight shake is occurring. I also noticed that my steering wheel was not in alignment and the truck was pulling to the left right from driving off the dealer lot. I brought to attention of sales rep who requested truck be looked at. Dealer took truck back and said truck was ok. I took truck back and noticed it was still doing the same thing and steering wheel was off.
I contacted the dealer and told them to take back truck and fix it because the alignment was way off.
I recieved a call from dealership to inform me that the right front was way off in aligment as I was told it was from manufacturing since the truck was brand new.

It seems that at manufacturing something is occurring with alignments and steering wheel placement. I hear allot of people complaining abaout same issues. I did have the tires road forced balanced as well to stop the shaking at higher speeds and it did resolve the issue. You may want to consider road force balance the tires. If dealer cannot do it take to someone who can then take bille to dealer for riembursments. I did.

Hope that helps.

What is "road force balance"? I've never heard that term. Are we talking spin balancing or something else?

A dealer in Canada diagnosed my shimmy & gave me the TSB for new heads,but the dealer here in the U.S. is not listening. My god these dealers are stupid! How hard is it to fix a customer's vehicle without hassle?

Any chance you could PM me a copy of the TSB? I have a shimmy at around 105 kph. My dealer is aware but haven't had it in yet.

Head replacement on 2014 ram ecodiesel

There is a recall/TSB for head replacements on some eco diesels for a shimmy that feels like a suspension/tire issue. I've not heard of anyone actually qualifying/getting it done though.
Well it seems that although it is not an official recall, I dropped my truck in this morning to have it looked at for a shimmy at 1800 rpm that felt more like it not shifting smoothly or motor vibration. Got a call this afternoon that it needed the heads replaced!!! Long weekend and absolutely needed the truck for a trip we had planned. Could have been a disaster but the dealer is providing a rental truck for three weeks while they wait for the parts and do the work. I am not that happy as this is the only vehicle we have but in general it has been a good truck with a few minor problems which the dealer ship has been supportive in getting the work done without interfering with our daily lives.
