2017 CCSB Z71 Silverado....just hit 1K...the shake, or vibrations have really seemed to kick in when I'm cruising around 80mph on the highway....Unfortunately I didn't know this was an issue before I bought the vehicle, and didn't seem to experience it during my test drive on the highway....Seems like from everything I've been able to read here, it's not too promising a future....have to drop it off at the dealership Tuesday anyway for an unrelated matter, might as well bring it up then.

 

Great!

I don't have much opportunity to cruise at 80 mph but have done so a few times. If I noticed a shake I would go to my dealer or tire store and have my tires and balancing checked. Don't assume you have serious issues because of an internet diagnosis.

Donstar is right, because it took a while to start it could easily be a tire or wheel issue. Sounds like yours may be an easy fix.

The 74mph shake is the bad one. It kicks in at 74mph and above if yours is at 80 probably just a tire. I had it bad and they got most of it out with tires and a bad rear end. Still not 100% for me but I'll deal. Tires will fix a huge chunk of it especially if you have the crap wrangler Sra if you do start pushing for any thing to replace them. They are terrible and get worse with wear

My truck shook at 70-75 when I first got it. Took it in and they had a new guy that rotated the tires, but forgot to balance them. Road force balanced and it was perfect. I have since then put new Michelins on it and still no vibrations.

Dropped my truck off at the dealership today to have the "vibrations" addressed.

 

They gave me an identical Silverado CCSB Z71 as a loaner..however instead of the stock z71 wheels, it has 20" wheels on it (only difference). All I can say is HOLY CRAP! If they can get my Silverado to ride as smooth as the one I'm burrowing I'll be a very happy man. It was almost luxurious, enjoyable and well dammit, how I expect mine to ride.

 

Here's hoping it's just out of alignment or a balancing issue.

Now you know what you can expect! Please report back!

Little update:

 

Got a call from the dealership today, stated they road forced all wheels and found them to be in spec, however they're still getting a lot of vibration in the truck...going to hook it up to a peco? I believe they said? Going to keep it another day....

 

Only positive in this is that they've admitted it IS vibrating, and aren't just pawning it back off to me.....yet.

 

Guess we'll see.

      Some Assembly is Required

      By Grumpy Bear · Posted

      How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.

      Gas Prices

      By Grumpy Bear · Posted

      Out and about yesterday on a long Saturday drive I passed a lot of Shell stations. My preferred, so I pay attention. Lot's of small town Illinois so not six stations in three blocks like the city.    Everyone of them over a radius of say 100 miles had regular at $4.19 but one which was the one closest to home at $4.15. However Premium pricing varied greatly between 85 cents over regular to $1.50 over. I'm not counting the price of the station with the lowest regular so the reference is the same for the remainder and all within the same brand. However the spread discrepancy holds across all brands.     @txab, any thoughts on that?

      Future GMC Jimmy

      What are your thoughts? The Chevy Blazer relaunch was an epic case of 'lunchbag letdown'. Jeep Wranglers and Ford Broncos stick out like a sore thumb.    The AI photos do not look like a 'retro version', but shrunken Tahoes. Get away from the 'futuristic look'. I've seen two concepts. One had rectangular headlight like a Rivian and the other way to big should include dual round headlights like the early version.   If not this would look OK   At least it has GM styling (albeit the K2XX) A lot of the images floating around look like Bronco IIs or the current Bronco. Looking at the Broncos in my area (central Ontario, it seems to be a mix of 2 doors and 4 doors, 'mall rated' to ones that could go offroad.    I'm sure a AT4 and AT4X RPOs could be outfitted similar to a Rubicon if the braintrust understood the whole offroad scene. Crosing my fingers that if it does see the light that the front air dam/bumper doesn't extend below the center line of the tire...

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      And overpriced. I was in the Oshawa Truck Plant when they were being built. Very few. I could count on one hand how many I've seen since
