There is a difference between the Dealer balancing the tires and having a road force balance. Did you get a print out showing the percentage(I am not an expert but I believe 15 and below is acceptable) at each wheel. If so maybe you could post it and one of the experts on here could give you their opinion. Good luck.

My shaking issue has been fixed so I will tell you what fixed mine and I would almost guarantee this will fix them all. I was building up my 6l80 with some performance parts and sent my shaft out to

Well my symptoms where just that.... a SHAKE! It would shake between 50-60 the whole cab would shake. It felt like King Kong was trying to shake me out of the truck. I could even feel it in the steeri

You could check it yourself with it still in the truck. Just put a dial gauge on a good sturdy mount or base with the back wheels raised and watch the dial indicator as the driveshaft is rotated by ha

No Road Force balance, just your everyday normal balance at local tire dealer.  I will bring the Road Force topic up to mechanic today and ask for a print out to post.

Thank You Tahoe02!

After further investigation, looks like I don't have the Chevy Shake after all, instead I have the Sierra Shudder, caused by a bad torque converter, so says the mechanic who seen and fixed this problem several times on the 2015 Sierra's. We shall see once the parts arrive and replaced!

I was at my brother in laws house a few days ago. He just bought his 4th suburban, he buys them used and drives them to the ground. The sister in law took us out to lunch, he couldn’t make it. I didn’t have the heart to point out the vibration and shake I was noticing. He going to ask me I’m dreading it.

No More Sierra Shudder!

Torque Converter was replaced and the vibration is GONE!!!

Time to go on an Adventure.

Hello I just read the problems you were having with your truck I have a 16 Denali 6.2 8spd I’ve the same issue as yours it shakes under light throttle from the get go I can feel it in the steering wheel as well ,,,did yours shake at 70+mph ??? I’m very frustrated as I’m not in the states my truck was imported from Dubai To another country so the parts availibilty is limited.... I did however balance the tires which improved a little but not completely eliminated.

did the tachometer jump when the shake occured? and was it constant or intermittent?

Having the same exact issue, could you tell me if you were able to fix the vibration?

Yea I found a fix to the issue. I sold the truck! No joke.

Dealing with the same problems! Was it fixed once they replace the torque converter?

They did work on my torque converter back in 2016 eventually GM replaced the entire tranny for a brand new one. 2 years later in late 2018, the exact same thing started again on a trip up to my lake house. As soon as I had the time, I went straight to the ford dealership and sold the truck in a swap for a 2018 fi150 platinum. Couldnt be happier. I do miss the big 6.2 v8 thought

I have done the following with no success: 2014 Silverado 5.3L crew cab 2wd

 

* New pads and rotors

* New shocks all around

* New U-joints with balanced drive shaft

 

The worst is at 70-75 mph but I do get the shake on occasion at +45 mph.

 

I am going to have my tires balanced and chalk the tires just to make sure I am not having a tire slipping on the wheel.

 

Any other suggestions? HELP!

My truck is doing the same thing your truck is doing. Did you ever figure out the issue?

My problem is not the shaking caused by anything in the running gear.  My issue on my 6.2L 2018 8 speed transmission Silverado is predominantly when running in drive and it drops the motor to V4 from V8 and under torque it will shake you teeth out until is bangs it way back to V8 mode.  The GM bulletin fix of changing the Transmission filters and fluid did not work. Applied the bulletin at 42K miles and it has had no effect on this issue.  Yes, I can achieve some improvement by shifting the vehicle into M from D and selecting M7 as the as the gear and this prevents the truck from shifting to M8 and from shifting to V4 from V8.  It still may shift ruff in the lower gears, but the issue is really when it is trying to run in V4 mode.  Noone seems to address this issue specifically.  They are talking about changing and balancing tires and all those things, but it is not my problem.

      2012 Sierra 1500 AC issues

      By Fishbones · Posted

      I just started having AC issues with my 2012 Sierra. The symptom is blowing warm air on all vents.  Here is what I have checked so far. Compressor clutch appears to be engaging and cycling  I checked all fuses and relay, no issues. The only thing I have notices is the short line that comes from the firewall is very cold / frosted. This line is approximately 12 inches long. The coldness stops when it hits the first line connector. As far as AC compressor - At first start the clutch engages, runs continually, Short AC line frosts up. After idling for several minutes the AC line thaws out some but is still cool and the compressor clutch starts cycling on and off every 5 seconds.  Any suggestions on what to look at next would be appreciated.

      OCI, not when but why?

      Unless you are using a bypass filer system with a Beta of 1000 at 2 micron the commercial filters we have access to, even the very best of them, are poor at the 5 to 10 micron range the typical UOA test can 'see'. Point is there are some truly awful filters being sold A 45 micron Beta 75 filter is what Dyson used to call a screen door on a submarine. That leaves wear metals disconnected from filtration unless particulates are larger than the test can 'see' and yet captured by the filter...which is its job. If that is true then you have a major issue screaming at you.    The graph isn't mine. It belongs to GM and their study on this area. I looked up those studies and provided those SAE tech paper addresses multiple times. Machinery Lubrication displayed it and confirmed it. So if you have doubts about the study you'll have to take it up with GM Engineering. Just like you would have to take up a difference in opinion about the meaning a word with Webster or the length of on inch with the National Institute of Standards and Technology.      Most manuals have two schedules. "Normal Service" and "Severe Service". On it's face it tells you that oil in severe service is more highly stressed and doesn't "Last as Long". The item to bore in on is LAST...what does that mean?    It's the same question one asks about how long to toast bread. What are the inputs? Bread type? Wattage of the toaster? Distance from the elements? What is your preferred level of done?    So lets paint this with a broader brush. Oil is made up of the base and the additive package. The first is altered by heat and oxygen and later is sacrificial with a finite life subject to inputs toward that end. Resistance and supply.    It is the reason an OEM's OCI's are determined by 1.) the specifications of the recommended lubricant and 2.) risk management toward the bottom line. Those lubricants are also subject to cost effectiveness for the OEM.    There is a tendency for most people to believe that the OEM recommended oil rest on the top shelf and that anything other is lesser than. Truth is there are more oils on higher shelves than those on the lower shelf below the OEM's. They make that choice on COST TO THE OEM. Testing is incidental to the margin.    GM makes MONEY, the car/truck is a TOOL to leverage MONEY. Insert whatever car brand you like. Until you forking over a million plus COST not quality is the driver. Thus it is by DESIGN the recommended OCI's and oils fall well short of 'best practice protections'. Proof isn't hard to find. GM Ecotec I-4 2400 breather system and cold start PCM tuning has killed more motors and resulted in more litigation for those that used the 'recommended' practice than GM could bear. What was their response? SHORTEN THE OCI. TWICE.    I don't know how long to leave oil in an I don't know how the oil will respond to MY circumstances and because I don't and can't blanket statement or anecdotal evidence my way out of it.....I TEST and FIND the right OCI for the oil I CHOOSE. There is no shortcut but there is blind allegiance. I don't blindly trust anything.    People hear the word 'detergent' and believe that in the context of oil it means the same thing as laundry soap... Only in the most rudimentary way. It's the first additive to give up on you and they are putting less and less with each new API standard. Solvency can be used but it cost. Some unique undisclosed chemistries can be used. Valvoline R & P in example. OEM's haven't an interest in anything they see as limiting market participation. Whatever.

      By KARNUT · Posted

      For some unexplained reason my father wanted a salvage yard. As we were getting the family business off the ground one brother ran the salvage yard. We gathered there when rained out working on pipelines in the eighties to pull parts. Perfectly good running vehicles would come to us simply because they wouldn’t pass emissions inspection. We were able to swap parts and sell some of them. I got a clean old nova with a bad engine. I pulled a perfectly good small block out a Camaro. A father and son project with a rebuilt engine. The son couldn’t get the engine running right. The problem was the spark plugs weren’t gapped. The 90s vehicles probably widened the gap of shade tree do it yourself engine repair. My do it yourself hot rod repair stopped at the 70s. After that my trusted mechanic kept them in running shape.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I have an old dental chair in my shop. Something I got for free and apparently it has more than scrap value? People collect them although mine isn't restored or anything. It's visually interesting (1930's Ritter) which is why I like it. And it IS decently comfortable if you kick back.   When a good buddy of mine saw it he said, let me guess, Atlas. It's a conversation piece? As in, you ask the questions, they do the talking?   Where do you hide the jar of teeth?   I would never.

      Are we talking about the same thing, though? The 7 versus 3 wear metals was from Lakespeed's 3.0-specific oil brand comparison test between AcDelco oil and Mobil ESP. The filter remains a constant so whatever excess particles the AcDelco oil is producing aren't being filtered out.   I'm assuming there's a parallel comparison to be made; IF the filter can filter down those particles, engine life increases, and your graph makes the case that a better filter (lower micron rating) can increase engine life. Introducing fewer particles AND filtering those particles with higher efficiency is the best of all worlds. Good oil, good filter.   Where we may disagree is the "baseline relative engine life". I'm more apt to believe the base engine life value is 200k+ on very average oil and filters, "bulk oil of unknown brand and white-label generic fleet-grade filter, Jiffy Lube"   Going from a 10 micron filter to a 5 micron filter should boost a base 200k to 275k in a vacuum as a single factor alone.   Here's the whatabout: How does regularly changing the oil and filter ahead of recommended schedule influence baseline engine life? Most people aren't going to science the heck out of this stuff or ask about Micron ratings, HTHS, or wear comparison tests at Jiffy Lube. Most of the Jiffy lube techs would say they need to call their tech support line to even try to get an answer.   --   Because we love anecdotes here, when I was fishing for 4.3 parts at a local yard this weekend, ALL of the 4.3 vehicles had well over 200k. I love looking at odometers of junked vehicles. How far did THIS go before landing at the crusher? The ones that still had engines weren't seized. None of them were vehicles I'd consider were Amsoil queens, in fact most of them had some kind of service cling-sticker in the corner of the windshield indicating it probably had very average maintenance services. Even the fresh parts rigs- I'm not sure taking an S/T series to 400k has much value considering the running value of those vehicles was probably somewhere around $1,000. 25+ years is a good run on time alone.   The intake manifold I salvaged had clean and bright pool areas. As expected, I found the fuel lines in the manifold rubbed through, just like mine. I'm guessing the lines on that donor truck started leaking, the truck started running rough, and its owner said that's enough I'm unwilling or can't take it out of service for several days, or spend $1000+ to repair it at a shop, it's simply time for a newer more reliable vehicle (or, more than likely, this is the 2nd, 3rd time this has happened in the truck's lifetime). While I don't count on my Blazer for reliability, the thought of giving it away for parts at certain points during my adventure, and being mentally free from its needs has has crossed my mind. I'd be losing $1500 or so, but I can only make more money; not time.
