You are gambling on whether GM will actually issue a recall to fix the issue. Otherwise you could see the resell value plummet once word spreads like wildfire throughout the automotive industry.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

I concede, if my trucks always had problems I would be a unhappy camper as well. I knock on wood that mine remains trouble free as all of my prior GM vehicles have.

Dodge buy back. That should do it and the only good looking trucks on the road are GM. Always have been and always will be.

 

Too bad GM is not buying back THEIR screwups. I guess they'll wait until the Gubmint orders them too also. Plus we're talking about older Rams vs current GM's. I don't care which company it is. I think they all dropped the ball with all this outsourcing and foreign plants. Everyone must make their own decision based on their own situation. If your vehicle has problems and the manufacturer refuses to do the right thing, then move on. It's not worth the hassle anymore. If you actually find a good truck whatever brand, then keep it and count your blessings. The days of brand loyalty are over because the manufacturers no longer have loyalty to their customers.

OK, so...

 

I know some folks think the ring and pinion in the rear diff is the cause of the vibrations in our trucks. Some of you have had them replaced by GM...but how do we know the replacement parts aren't also out of spec? After some research I found two aftermarket replacements, one by Motive Gear and another by American Axle. Anyone adventurous enough to try one of these?

 

 

American Axle:

Motive Gear:

http://eastcoastgearsupply.com/i-127200-gm-9-5-motive-gear-ring-pinion-3-42-ratio.html

 

 

The motive gear set is for the older 9.5 rear end which has the 14 bolt cover. The k2xx has a 12 bolt cover and uses a different gear set. The AAM gear set is the same ring and pinion that GM uses. The entire rear axle is built by AAM for GM. In order to use the the gear sets for the old 9.5 it requires adapters, new bearings and a diff cover space to clear the differential. This rear end has been out for 2 years now and no aftermarket manufacture has cut gear sets for it. The only gears that fit without adapting are the AAM's which are what are in there to begin with.

i know you all will think I'm crazy, but I think it's an aerodynamic problem.

Every truck would have a vib then. There are hundreds of thousands that do not or there would be many more of is here. It could even be shitty wheel bearings allowing the wheels to wobble. My dealers been replacing quite a few rear wheel bearings.

 

I correct myself, its tires, drive shafts, rear ends, AFM, and all of the above and in any combination...

On my 2nd 14, I had a very minor vib 73+. I bought a set of LT 275 70 18 Terra Grapplers and replaced my SRA's that only had 1200 miles on them. My first truck had everything rear of the tranny replaced several times w no fix. I was lucky and it was only the tires.

 

Heck, it might be the weight of the LT tires I put on. They're MUCH heavier than the SRA's.

I had my truck at the dealer yesterday for the 2nd time trying to fix the vibration problem and they told me they cant work on it. The vibration exisits from 70-80mph and their techs cannot drive the car faster than 55. I suggested I would drive and take the tech with me....they declined. Beyond frustrated at this point, Im putting in a call to GM on Monday so I hope that gets me somewhere.

jmckeone,

Do not bother calling GM as they will not do anything for you. You are better off to call another dealer to look at it. Once you contact GM they will refuse to do anything for you at any dealership. Or you will get the response "it's working as designed". At least that is what happen to me.

In this event, I would ask them why they attempted to try and fix anything in the beginning? Are their roads there with the speed limit posted of 70mph? Also I've always wondered, if GM can't "test beyond 70mph" why do they allow them to go any faster? What about people in Texas and Montana where the speed limit exceeds 70mph? When buying a new one, the sales person has no issues for you to speed and "see what it can do!" Once there is an attempted fix from them, they are admitting they know something is wrong. We all have every right to play the same game they do. Keep jumping through the hoops guys, once the GM rep drives your truck, ask him if they would live with it and accept it? Don't lay down and take it. The driving in M5 suggestion is just plain unacceptable.

Definately not because mine was vibrating only between exactly 20 and 30 mph and smooth as glass at any other speed .

Good looking doesn't mean much when your truck is in the shop half the time. I've been looking at dodge quite a bit lately too.

Picked up my 2015 Ram last weekend and couldn't be happier after trading in my Silver-Vib.

It's strange because it's like a breath of fresh air after Vibrating for 9 months I keep expecting to feel it again with my new truck , but nothing its so smooth ! It's like being on Vibration alert though lol .

The only thing I miss is the looks of the front end of the Silverado but the Ram looks pretty good and has nice body lines a long with the rear end.

I'm at my local Ram dealer right now. Someone talk me out of it.

Just do it !!

After my test ride I was sold , handled nice for me on any turns and very smooth , I like the interior a lot to and the seats are super comfortable .

      I am sure that was quite the pass experience and not a great place to experience during the winter when the conditions are not good. I've seen video of that pass and also more detailed information and pictures about the wrecks at that one hair pin turn where tractor trailers have flown right off the cliff and I am sure from all the warning signs that you know the exact curve that was !. After all there is a reason why a song was made about Wolf Creek Pass !. By the way and I didn't realize this either when I bought my truck as its nothing I even thought of that would be programmed into the cruise control and this occurs in either the basic or the more advanced cruise that controls your distance behind a vehicle and that is the brakes going down a hill are being applied as soon as the vehicle goes a certain speed over the set cruise speed. While it certainly does force downshifts in the transmission as you found out with cruise on while going down hill, its also dragging the brakes as needed to keep the speed controlled to what the cruise was set to. For me, I find that unsettling simply because I have no concept then as to how MUCH brake input is being used a and just how hot are those brakes getting and the wear factor as well. I can see that system getting a person into trouble on long mountain grades while pulling a trailer as it would not only be standing on the brakes of the pickup without any driver input, it would also be automatically applying the trailer brakes and it could cause a run away unit by overheating the brakes. Its one thing on a shorter hill and if the driver allows it to do its thing but on a long mountain grade is where things could get so out of hand. As someone a while back on this forum said, they had someone following them at night I believe on a down grade and had the cruise set and the person behind them could see the brake lights being energized all the way down the hill. I figured when I saw your comment that you didn't know and would have no way of knowing that your truck was applying the brakes and that you would and rightfully so assume you only used the brakes when you pressed on the pedal to slow down more than the cruise set speed for the slower sharp curves. So its good knowledge to know this about the newer GM trucks, certainly when doing any descending on long mountain grades. In the future try kicking off the cruise and use the the manual mode on a pass to see what that is like as I know myself when I first experienced it I thought no way can this engine be holding me back this well and tried the same hill in manual mode and sure enough the engine was revving way up and still could not hold the trucks speed down like it could in cruise mode.    Fuel mileage, that is where a really low sleek type of car can do better at higher speeds, certainly it starts sucking fuel too but a tall pickup is pushing massive amounts of air and also allowing a lot more air under it and the tow mirrors as in elephant ears pushing through the wind  as well. Driving like grandpa is about as good as one can do when driving one of these if trying to get the best fuel economy they can. I bet these trucks would get the best mileage they can if driven on a freeway in Florida if not busy traffic at a sedate speed and that sea level elevation without hills, vastly different then Colorado !.
