Chevy Silverado and GMC Sierra Noise and Vibration



  • I have a 2003 chevy silverado 1500 4x4. Last week my front end started to vibrate/hum at around 60 to 70 mph. I thought that the 4 x 4 axle actuator was engaging the front axles causing the vibration. I pulled it and it wasn't engaged. I noticed gear oil had came out of the vent hose on front differential. Feels like the vibration is effecting power as well, like its causing resistance. I would like to resolve the issue. I'm affraid driving it like this will cause more costly repairs.
  • hi folks
    well i must say i am a very very dissatisfied with my new truck!!!!!!!! this will likely be my last GM for sure. i wish i had my 2003 GMC back!!! i have owned it from middle of sept and its been in the shop every thursday except 2 thursdays since i have had it. first i took it in for vibration in the front. they have force balanced all the wheels, replaced 1 rim and all 4 tires. the service advisor tells me it is normal???? like WTF is that. i have 3400 miles on it. my 2003 drove like a dream. i am in talks with gm now, but it looks like i will get nothing done?!?!?!?!?! when i took it in last thursday, i complained about a noise in the back end of the truck thinking that the spare tire may have come loose? nope, they called me and said they were replacing the rear axles!!!!! like 3400 miles and it needs new axles!!!!!! my truck is red i am already thinking it should be yellow, A LEMON!!!!!!!!!!!!!!! i also took in with me last thursday a piece of trim that fell off when i was washing it!!!?!?!?! like WTF is that? there was no glue on it. this truck was built in indiana not mexico, where i could see this being a defect!!
    as a new vehicle owner i am VERY VERY DISSAPOINTED with my new truck. i have owned 5 new gmc trucks since i started driving 32 years ago, and i now think i should still listen to my dad when he tells me to drive a ford!!
    i am so lost for words as im disgusted about this and that the dealership here in Chambersburg PA, Jennings, are not going to do anything about it but tell me its the nature of the vehicle.
    i tend to disagree with them as a $40 k truck should drive flawlessly!!!!!!!!
    i also dont care much for the way the 6speed trans holds in gear till it needs to shift. NO WONDER ITS SO HARD ON GAS!!!!!! which doesnt impress me either as my 2003 got 20-25 mpg and i havent got over 16 with this new one and its 8 years newer! being that much newer it should get better gas milage than my old one!!

    I AM JUST SO UPSET OVER THIS BULL CRAP OF DEALING WITH A NEW VEHICLE. i bought a new one not to be in the garage and i now have spent more time there with this new truck than my old one....SOMETHING WRONG WITH THIS PICTURE!!!! no wonder GM almost went under...maybe they should have with the junk they are sending out on the market to sucker people in to buy!!
    gm should also look into some more invigerating colours for their junk like YELLOW!!!! if you got LEMON,it should be the right colour!!!!

    sorry folks...just sour taste in my mouth...LIKE A LEMON.....

    dont know what to do now with this hunk of junk!!!
  • Neil,
    I am sorry to hear how dissatisfied you are with your new truck, and can understand how having a new vehicle in for repairs so frequently is frustrating. It sounds like, from your post, you have contacted Customer Assistance already? Were you provided with a Service Request number? If you would email that to us, or the last 8 digits of your VIN, we would be happy to investigate the situation further.

    hi sarah
    well no i dont have a service request number,wasnt given one. if you could help that would be greatly appreciated as i dont think the person handling this has a strong enough personality to deal with the service adviser.
    i also would like to mention that i had to borrow a vehicle as one was not given to me or offered. it has been at the dealership for over a week and i havent heard from them at all? the only way i have heard or know anything is from the district specialist. why is this? why hasnt the dealership called me? my last 8 digits are b2309253.
    why have i had to borrow a vehicle to get to and from work? and to top it all off, i am driving a 2001 saturn with 180,000 miles on it, which at 45-65 miles an hour has NO VIBRATION WHAT SO EVER. but i am being told that this is normal with the new GMC sierra and it design. well if i had known of this i would not have bought it. i have had several trucks out for test drives since last feburary when i decided to buy a truck. i chose new as the used ones were not in nice shape and the prices were like new, so i bought new. WHAT A MISTAKE this has proven to be. but none of the ones i took for a drive had no vibration at all. and some of these vehicles were GMC,s.
    this is POOR service and POOR quality from a company who has been around for so many years. a company who took the publics money to save itself from bankruptcy.
    where is the dedication to the public that general motors wants to buy their product...NONE!!!! but expects the public to buy their product and put up with this kind of treatment!!!
  • Hello Neil,

    I would like to get a Service Request established for you. Unfortunately, when I used the last 8 digits of the VIN provided, I wasn't able to access the vehicle's information. I'm sorry for that delay.

    If you're willing, please email us the full VIN, as well as your name/username, complete contact information, and the name of your involved dealership.

    Thank you in advance, and I apologize for the delay.

  • I have a 2000 chevy truck 1500 the rearend and trans messed up at the sametime so we had them both rebuilt and now it fills like u joint bad but they have also been replaced and between 50mph and 70mph it has a viberation can't figure it out. had tires checked they where ok it is happening when u hold it at a steady speed.
  • Bought a 98 K2500 Silverado 4 years ago cheap as the motor was bad. Had Chevy install a crate stock motor (350), transmission (4L60E) and transfer case (idk). Spent the next two years slowly squaring the mechanics and suspension away.

    Just recently had to have Chevy replace their transfer case (which had less than 10,000 miles on it - I didn't drive it much) as the chain was jumping cogs when in 4wd. They also had to repair an oil pan leak and a coolant line leak. Great - all under warranty. They had to pull the front differential to fix the oil leak so due to it's state I got a "new" one from a junkyard and had it put in. I asked them to drive test the tranny because it was "hunting" when it shouldn't in second gear AND it was shifting between 3rd and OD and then back and then back way too much at 35 mph ( cruise control of course). Except when I get it back, less than two miles have been clicked away on the odometer....hmmm. They said it was fine.

    Now after all that I have a vibration at 33-38 mph. I can feel it in the steering wheel and in my seat. So I had the wheels balanced, replaced two worn ball joints in the steering linkage, I even put a Contour cam under my truck looking for what the heck was doing it. No luck.

    At this point I am a little concerned about the Chev Service and I think I am on my own as they state the truck is fine and it had the vibration before they did anything to it. So I was just racking my brain... Going over the factory chev manuals for 98. And the other day while complaining about all of it, one of my co workers asks me if my drive line was "in phase".

    So there you go. Google it. Propeller shaft phasing, drive line phase. It's funny because the Chev factory manual states how important this is. It even has pictures showing all the drive lines and how they should be phased. So why then when I look under my truck, is my drive line 45 degrees off? This is a two piece drive line and it does come apart at the spline but it only goes together one way. So my truck and many, many others roll off the factory floor with out of phase drive lines.

    So I just got my truck back today from a local drive line place and it feels great. No vibration. They removed my drive line, cut it, phased it, welded it back together, balanced it and reinstalled it. Guy says he does it a lot.

    Also on the drive home I noticed the tranny was not shifting back and forth. Could it be that the drive line issue was putting "junk" into the data that shifts the tranny? And the pedal response feels better now. I always felt the truck was a little sluggish but shrugged it off as symptomatic of a 3/4 ton 4x4.

    The elliptical (as opposed to perfectly round) rotation of an unbalanced, out of phase drive line robs power and response. I suspect my gas mileage may improve as well. Thanks for reading and I hope this helps some one.

    Oh boy, I can tell I'm in for it. Two weeks ago I traded in my 2004 Sierra Crew Cab - man I loved that truck... And bought a new 2011 Sierra Crew Cab. 42 miles on it when I took it off the lot. The next day driving to work I noticed an annoying vibration at 50-55 mph. It's in the seat, pedal, steering wheel. My kids got car sick riding in the back seat... The service guy looked knowingly at the service manager the other day and said to him 'vibration at 50mph'. Now i know why. They tried to tell me it was the tires and I should drive it some more and it will go away. 800 miles on it now two weeks later and it's more noticeable than ever. Dropping it off tomorrow for an 'alignment'. I gotta tell you it sure feels like the tranny or an unbalanced drive shaft... I am more upset than I can express. I have been swindled out of 40k. Won't happen again.
  • Looks like today is alignment day - please keep us posted on how it goes! I hope that the vibration is resolved, but if not we're available to assist in follow-up.

    Well, they're keeping my truck for another day or two. It looks like it needs more than just an alignment, but they say there is a fix for it. (There is a GM Tech Bulletin about Suspension Vibration that specifies a fix for this) I sure hope whatever they do takes care of it once and for all... I have to say the service department where I purchased my truck has definitely been helpful so far.

    please let us know about this Tech Bulletin. i have a 2010 sierra 1500 with vibration problems. 23000 miles new gm wheels and tires. balanced twice. still vibrates. dealer says it the tire balance.
  • I also have a 2010 Silverado ext. cab that has 17,000 miles on it. The vibration at all speeds began to occur about 4,000 miles ago. So far the dealership has replaced the rear shocks, the tires, checked alignment, and still no resolution. If there is a TSB about this item I will be more than excited to hear what the solution is. Any type of bump, expansion joint, or deviation in the road will cause the entire truck to jounce from left to right. On the expressway going 70 m.p.h you will experience the same excessive bouncing. A cup of coffee in the center console will shake itself right out. There is no excuse for these defect(s) and I will be glad to hear of some sort of resolve. My dealership is about done with being "participative".
  • Thank you for your patience, although I can understand if it's wearing thin. I am unable to access TSBs as a Customer Service Representative, but hopefully we'll hear more from gmcwoe. In the meantime, if you would like to open a Service Request with us so we can help in working with your dealership towards resolving this, please get in touch via email with more information (your name/Edmunds username, phone and address, the last 8 of your VIN and current mileage, and the name of your dealership).

    I have a 2007 Silverado LT 6.0Ltr, 4X4 ( not classic ) I "had" a tinny, obnoxious vibration on acceleration at exactly 1500rpm. As recommended on another website, I went under that truck at the passengers door and located the screen mesh on the exhaust pipe. I moved this screen mesh back and forth for about 15 seconds. Went out for a drive and the vibration is gone. Mmmm....what's up with that. If the vibration returns , I'll try it again.

  • On my 2010 Silverado under the passenger side the dealership replaced the heat shield because of an improper assembly the shield would rattle.
  • I have taken my 2010 Silverado to the dealership once more today to see if the can remedy this situation. As of yet all that we have done is new tires, rear shocks, checked front suspension, steering, driveshaft, and balance of tires. I get the feeling that I am about out of there patience in terms of them willing to look into a problem that they can't seem to find. I have taken them personally in the truck on multiple occassions down the road to have them experience this "jostle" of the entire vehicle as it traverses over bumps or expansion joints in the highway. An up/down motion of the vehicle is normal but when the vehicle wants to shake left and right and cause the entire vehicle to move in such directions, I no longer feel safe to operate. I have driven 4 different Chevrolet Silverados to almost 300,000 miles each and the 2003 that I currently also operate still rides and traverses smoother down the road than the new one. Figure that one out. We also drove a brand new truck off the lot on one occassion to see if the problem that I had was in the new truck. Of course we could not replicate that symptom in the new vehicle and they service technicians complied. Ugh, you know at the end of the day you shouldn't have to do this. Isn't that why I bought a new vehicle in the first place. NO PROBLEMS.....HMMPH. In regards to you opening a service request what information is needed and what more does that do than me returning to the dealership again?
  • For the service request, we would be working with the dealership towards trying to resolve this concern with your Sierra. To get it started, we would need your name/Edmund's username, contact information (phone and address), the last 8 digits of your VIN and current mileage, and the name of your dealership. Since you've been working with your dealership extensively, your case would be forwarded on to your district specialist.

    Hi evanewski,

    Your quote:

    "We also drove a brand new truck off the lot on one occassion to see if the problem that I had was in the new truck."

    Wonder why they had you do that if you have a valid complaint about your "warrantied" truck? Sounds like a quick, convenient way to say "see Evan, they all do that so quit complaining!"

    Was it the Sales Manager or the service department's idea to "drive a like vehicle"? I'm guessin' it was the GM Dealer Sales Manager.

    In addition to other quality issues, my 2011 Sierra's steering pulls right and jumps a bit over bumps. It has since new. I don't care if GM has "run out of patience" with me. I'm going to keep telling them to correct the numerous problems with the new truck.

    You're exactly right; why did we buy a new truck?

    My old truck ran better!
