Well I finally fixed my vibration problem. I got sick of dealing with GM and the dealership and I couldn't stand driving it on the highway. So, I went and bought a 2015 Ford F150. I can say the interior of the GM is nicer, but the ride and drive, Ford has it. I also got the Ecoboost 3.5 and it is quick. I think it is quicker than my GM and My GM had 6.2L with 3.37 rear end. So far I think I made the right choice.

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'm about to do the same. I'll get the 5.0 though.

To the case of this vibration I would like to describe my vibration issue and how it is bieng resolved.

 

First the car is a regular cab 1500 sierra

 

The vibration starts at 120+ KM/h

When I set the car on cruise I feel body vibration, where i can see and feel the dash, and seats shaking plus anything in the centre console.

Took it to the dealer a couple of days back.

Today I got a full report on what has been done to my truck.

They started off checking engine mounts, gear mounts, front rear drive shfts, all shocks, front arms,

They checked if their was any misfiring, however non of this was on my truck.

They decided to make sure my wheels were properly balanced.

After the check it turned out that two tires needed to get changed due to many flat spots.

They threw these two tires to the back and keeping the two properly balanced tires upfront till the new tires arrive which could take 15 days.

I could tell you that with the road force balancer and the best they could do to balance the set of wheels, 90% of the vibration is gone. I drove around 60 KM today at the speed of 135 KM/h and could really feel the difference.

Therefore goodyear eagle tires are just not of that high quality, my friend is using them on a ford edge and is having the same issue, his car used to drive smooth till ge changed them with these set of tires.

Moreover the vibration at idling is said to be because the engine is running at both v4 and v8 and cant keep its mind at one. This is AFM as the mechanic told. So I gave a call to one of my friends who tuned his car to only run V8. And the idling vibration is well decreased.

Hope this helps and just take it easy reduce your tension and just hope its something silly.

For the vibration at idle you probably need the 3mm right side motor mount shim.

Edit: As for AFM, it does not put the motor in V4 mode while its idling.

The vibe is really starting to rear it's ugly head on my Silverado CC standard bed at 15,000 miles. I have aftermarket wheels/tires and a leveling kit so I'm probably f$&@ed. I was really enjoying my first GM product too...

I had a set of OEM Goodyear Eagles on my '09 Impala LTZ and never had any vibration or flatspotting problems. Of course these tires were Z rated for speeds of up to 168 MPH, so there is no comparison to a SUV or truck tire that's just S rated for up to 110 MPH speeds.

Well it pains me to say that even after new tires the vibe is starting to come back...I really don't understand why or how but anymore I don't care. I am just about done with all this and going to cut bait and move on. I almost pulled the trigger on a Tundra TRD Pro Saturday but keep holding on in hopes of a fix. Dealer says it's tires and it might be but not sure why this truck is so finicky and I have to RF balance my tires every couple thousand miles but I am done!

Assuming the truck does not vibrate itself apart at 40K to 50K when the tires are shot and due for replacement, what is the consumer to do if they want to go down to their local Costco or some other tire shop for a replacement? Somehow I don't think the tire shops will swap out tires and perform numerous attempts to balance tires free of charge because the these trucks continue to experience vibration issues.

After reading every post in this thread, I don't think it's a tire problem.

Definitely not a tire problem. I have Toyos that road force less than 9lbs and my truck shakes like Michael j fox (sorry if I offended anyone). My 2013 Sierra got bought back for similar issues and I was able to get into a new 2014 Sierra and this one now shakes too. I am going to be visiting the Ford lot this week. I know the grass isn't always greener but it's gotta be a little better.

after reading through 300+ pages, I also agree it's not solely a tire problem. I'd still lean towards the resonant frequency of structure coinciding with vehicle speed or perhaps torsional/lateral vibration issues developing within the powertrain.

So my 2015 has been at the dealership with a bad vibration while sitting still and in gear. I have a case with gm and my dealership. Has been in the shop longer than I have had. Haven't even made first payment yet and has been at dealership for almost 30 days. With the answer to my questions 'we don't know what's wrong' any advice guys.

I have BFGs with good quality aftermarket wheels and I get the vibe at the exact same speeds as with the OEM wheels/tires. NO WAY it's tires. Good luck with the Ford.

Appreciate it! I am not certain I am going to go the Ford route as I do love almost everything about the Sierra minus the shake. What made you switch from the Ford to a GM product if I may ask?

I believe there have been a couple of cases of the vibration being solved by installing a complete new rear end, housing and all. I suspect that is the real problem, not tires. Exactly what, I'm not sure. But, I bought a digital electronic level and I am going to check the u-joint angles myself to see if they are right. My dealer said they checked them, but I don't trust anyone anymore so will do it myself. As soon as I get a free minute.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      By Chuck FB · Posted

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      By Grumpy Bear · Posted

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.
