anyone have vibration issues with their 2014 silverado 1500?

Your truck would not happen to have the towing package would it?

yep, but from what I saw in the online complaints its a gambit of all of them from 2wd to 4wd and regular cab to crew cab and extended cabs all seam to have a group of vehicles doing this with or without towing packages and there are two tire brands involved, the bridgestones duelers and the goodyears.

from what I saw in the online complaints, a few people have come across details showing the tires being put on the new trucks is a much lower quality of speed, load, and temperature ratings then the ones you go buy retail so while its a guess, I think its all caused by really crappy tires and also poor quality rims being cast instead of turned which makes them harder to balance even though in my case I have the steel wheels.

IMO it also appears they don't balance the tires at the factory because this new electronic assist power steering is "suppose" to absorb vibration from out of balance tires

its also affecting trucks with steel whells or aluminum and in all sizes 17", 18" and 20"

The reason I asked is that my brother bought a crew cab a year ago or so and is some kinda po'ed about the vibration. They have switched tires, balanced em, different driveshaft, and some rear end gear parts. He bought uniroyals for it out of his pocket. Say's it's better, but still vibrating. He's been on some forum and they figured out that the ones at the time had the tow package and there are different parts in rear end assemblies. He even bought some kinda gel pad and had a shop install it in the drivers seat.

as far as I know its just the 2014 model years with these issues but I guess any truck could have a similar problem

did he switch rims? because the service manager told me he has seen bad rims sometimes out of round (mostly with the mags) and a regular balance machine cant catch that that's why the need to do the RF balance (road force) see if he can borrow someone elses rims and tires to try out and know for sure if its in the drive train or the tires or rims because GM is clueless to figure out
problems like this, all they know how to do is change parts til they get lucky

RF balance machine looks like a regular balancer but it has a big drum to press down on the wheel to test for being out of round or egg shaped

the only thing they could be talking about is the towing package comes with the locking diferential added that's not on regular trucks so that must be what they are talking about

the ones I read about with the drive shafts or rear ends being an issue is those who had increased vibrations when towing, some to the point of thinking a wheel was loose

update:

I got the truck back today after they were "supposed to" RF balance the four tires they said they replaced.

as it turns out, it says on the paperwork that they just swapped tires out with another truck on the lot and sent it off to southern tire to be balanced but nothing was mentioned on the paperwork about it being a RF balance.

it was raining when I picked it up so no test drive, anyway on the way home it is still vibrating but not much (about like the last time I was tempted to let it go and keep it) but when I got home I took a good look at the tires they put on just to see if they were different tires but I cant tell if they swapped them all or just one or two.

the big problem was right there in my face, my truck has steel wheels with ss hubcaps and they clamped the wheel weights right over the hub caps locking them onto the rim!

it has a center cap you take off first before you can pull the outer ring off but they removed just the center caps to balance it and hammered the weights right over the hubcap as though it was the rim.

things are definitely looking very hinky at this point so im gonna call southern tire and see if they even have a RF balance machine because at this poinnt it wouldn't surprise me to find out they don't.

I got receipts for 2 repairs on same problem and Monday will be #3 so I guess they get 2 more tries before lemon law kicks in

todays update:

dropped the truck off this morning, the guy said they put the miles on the truck test driving it and sometimes put as much as 100 miles on them for problems like this to be sure they fixed the problem. yet they keep saying they don't feel it anymore and its fixed when its not

as to the hubcap trim ring, the parts guy showed it to me in the computer and the rim asnd trim ring are one unit in two pieces that are bonded together at the factory so they don't come apart separately and that's why the weight was put on the outside but they will send it back and have them rebalance it with only putting weights on the back side so it doesn't show on the outside.

on the way in today I noticed a wheel hop issue at 40 mph and the service guy admitted he felt it too but he said that's just how short bed trucks do because of the suspension . I explained the truck did not do this before with the other set of tires they had on the truck at first and in fact all I ever owned was several new short bed trucks and they don't bounce or hop unless the road causes it and on smooth flat even roads with fresh blacktop there will not do that just because of tight suspension.

left with rental truck again and i'll see what happens this time.

repair #3 for the same vibration problem is in progress
