Yep! This is what the engineers are telling the mechanics to do!

They tried this on mine and I told them what they could do with their half ass hose clamp fix. Then they sent my driveshaft out to have weights added on where the clamps were and the truck vibrated again. The clamps worked, but only as a temporary fix. Don't except that as permanent!

That's what my wife said!

Update: Got a call from the dealer today after requesting a buy back from general motors and it has been approved by the district manager. The only catch is I have to buy another Chevrolet which is not what I was interested in. So with that being said I am thinking about asking if they can put me in a 2016 Camaro. I am not interested in another silverado and don't really need a truck anyway. Just wanted one. Anybody else get something different with their buyback other than another truck?

Keeps us posted on what they say about the repurchase. That will be my next step. I picked my truck up today after being at the dealer for almost a month. I drove it the other day with the mechanic and it drove great, but I asked them to send out the driveshaft to have it balanced properly (after they used hose clamps to balance it). Took it out on a good 80 mile trip on I-71 where the road had been repaved and the vibration/ center console shake was back as if it was never fixed. That makes 5 repair attempts and over 30 cumulative days out of commission. Three different dealerships and still not fixed.

I went to the dealer today to check out my truck and test drive it and I have to say it rides a lot better on the highway but I expressed my concern on using hose clamps as a permanent fix for the driveshaft. They agreed to send it out to a local shop to have it balanced properly but didn't sound optimistic that the truck would drive the same once they put the shaft back on. I sincerely hope it does at this point. Makes me wonder how many other trucks they gave back to people with hose clamps as a fix. Not everybody knows how half ass that is!

Funny because it's probably true...

The update I have on my truck today is not a good one. The dealer called and said the vibration is "better". They loosened all motor, tranny, exhaust mounts and torqued them all back down. Then the genius field engineer decided to balance my new driveshaft with hose clamps. Is this really the best thing their engineers can come up with?

I would request a complete rear axle assembly if they wanted to replace just ring and pinion gears. I asked the mechanic working on my truck if he had actually had to do this with any of the shakers he worked on and he said GM is telling them only to replace ring and pinions because they don't have enough rear axle assemblies.

Update on my truck; 1 new driveshaft, 1 new front tire, 4 new shocks, multiple road force balances and still not fixed. The dealer finally got the engineer out to drive the 5 trucks that they currently have in for different vibration problems and he wants to pull my driveshaft out....again. How can I end up with two bad driveshafts? What are the odds? Why did they replace the shocks???smh.

I'm more interested if anyone has hired an attorney and what the costs/outcome was going that route. My situation hasn't escalated that far but I would imagine it would be easier.....

My purchasing dealer said I should take my truck somewhere else. So I found a dealer that has experience in the shakers and took it there. They've been great so far!

Same deal here, they first replaced my driveshaft and that made absolutely no difference. After all four shocks replaced and front right tire it felt like it did when I first took it out on the expressway (about 300-500mi on the odometer at that time). Not as bad but still there. When they gave it back to me last week all tires were within spec but the two rear tires were just barely at the road force limit which they told me was 15lbs. Something on this truck has to be causing all these parts to wear prematurely! The mechanic that replaced the driveshaft said he could see it bouncing around like there was something not right with it. Now it's back at the dealer and I'm afraid this time their gonna tell me it's all normal, but I know the vibration will come back as it wears out more parts. That sucks because thats more money out of my pocket if they eventually do buy it back.. Even worse, the dealer has two trucks ahead of mine with the same problem so it could be weeks till they get a field rep out to look at it.

There is a used 2015 with 2000 miles sitting on the lot at my dealer. I looked at the carfax and seen 5 service records on it. Hmmmmm......

I've seen where a lot of people were concerned with this being related to the larger diameter rims or the goodyear tires but I have the regular 17in rims with bridgestone duelers. One dealership has the pico pointing to the driveshaft while another shows it being a tire/suspension issue. As the dealership told me....nobody knows whats going on. Same problem since late 2013, you would think they'd have this figured out by now.
