Chevy Colorado and GMC Canyon Vibrations

I bought a 05 GMC Canyon w/33000 miles. It was not long before I found it had a bad vibration at 60 mph, was told it was tires so put top of the line Toyo's and vibration got worse. Power Chev. in Siblimity said it was tires so back to tire dealer where they rebalanced them and put truck up on rack to check for bad wheel or out of round but found nothing. Back to dealer, service manager happens to live close to me so suggested he drive it to work for a few days. 3 days later he calls and tells us it is a problem with this suspension and the fix is --150+lbs of weight between wheel wells and tail gate. Amazingly the vibration all but disappeared. There is a bulletin from GMC on this.

  • 04 Colorado crew cab w/Z71 suspension does the same thing. I have tried Yoko Geolander 265/75/15 and Goodyear Fortera Silent Armor and the vibration got worse. Do you know what the service bulletin number is? Anyone else out there have a solution to this continuing problem?

    I have this Bulletin that the dealership gave us 03-00-91-001B but I also found the below on the web and they tried it.

    99-05 Chevrolet/GMC Silverado Sierra suspension Vibration or Frame Beaming at 40-60 MPH Recommendation/Instructions:
    Test drive vehicle to confirm the condition. a beam shake condition will usually respond to concrete type pavements more than asphalt, so the vehicle should be driven over both surfaces if possible, Place 200-500 pounds in the pickup bed between the closed tailgate and the wheel wells. A beaming condition should dissipate
    If the concern is determined to be beam shake, this is a normal characteristic and no repair attempts should be made. A Field Product report should be submitted by following bulletin 02-00-89-002C.
    The weight that they put in the back of my pickup did not get rid of the vibration all together but it took enough of it away that it is comfortable to drive now.

    Hope this helps.

    Just a question...Is what you're describing a "shake" in the steering wheel, or a vibration felt "through the seat of the pants"?

    The first thing I did to my '05 Canyon was get rid of the OE General tires. They're worse than terrible. That in itself was the biggest part of the cure, but I still had a little shake in the steering wheel. It wasn't bad, but annoying. Just for grins, I took out the OE rubber sway bar bushings, and replaced them with polyurethane pieces. The poly allows the bar to rotate more freely, instead of binding. 99% of the shake is now gone.

    I also took the driveshaft to a reputable shop to have the balance checked, as GM shafts are sometimes suspect. It wasn't severe enough to have the warranty cover it, but they replaced both u-joints, because they had a slight bit of slop, and balanced the shaft. The cost was $75, and it did smooth it out a little bit more.

    Another couple of years, and a few hundred more dollars, and I should have this truck sorted out to where GM should have had it!
  • The vibration I feel is "seat of the pants" and has existed since the truck was new ,44K miles ago. Three sets of General tires by GM, same problem. I now use Goodyear Fotera Silent Armour but still feel the vibe after 30mph - 65mph. I'm also thinking about having the drive shaft re-balanced but I'm at a loss as to what else to try. I was told by a Chevy service manager that all Z-71 crew cabs do this and that I should "get use to it". Any further comments or assistance from other owners/mechanics would be of great help. Thanx

    I, too, have the Z-71 option. At one time, I thought the rear shocks had gone bad, so I removed them to check things out. In doing this, I found the shocks to be EXTREMELY stiff. I had quite a time getting the bolts through the lower shock eyes during installation, as the shocks were very difficult to compress. I couldn't do it by hand, I had to use a floor jack!!

    I'm sure that this is part of the problem, there's so little compliance in the suspension.
  • I just bought an 07 GMC 2500HD Sierra crew cab, and I also have the same problem with a vibration. Today the dealer had the tires re balanced with "Road Force Balance" I never heard of this I understand it's some type of new balancing machine. Not all shops have this machine.
    I am very upset about all this. Why should I have to go through this after paying well over $34K for a new truck with a problem? GM knows of the problem, but they are still selling the built in problem. I would like to return my truck, and get my money back.
  • I too just bought a new 07 chevrolet 2500 hd regular cab,This truck shakes like it has square tires since new,the dealer has changed the tires twice balanced them at two other local tire shops,this thing is not bad its the worst piece of crap I have ever seen! They cant fix it,I drove every 2500 on the lot today they are all the same! 40 to 65 mph,BBB autoline GM is going to buy it back !
  • I have a 2006 GMC 2500HD and i get a clunking noise in the steering frequently, and each time the steering shaft has to be replaced, this is the third time it has had to be replaced, i am sick of it, i was wondering do the diesels have the same problem, the truck sits, and it doesnt happen when towing, only driving around in city

    Does the 4dr, Z71, 2wd 08 Canyon have the vibration problems discussed here at highway speeds?
  • My 2004 colorado 4wd ext cab has a tinney vibration noise coming from the back. Dealer could not locate. Does it in neutral if give a little gas. Sounds like a loose exhaust but nothing loose there per dealer. The noise is very embarassing when others in the vehicle. Could the bed liner or tonneau cover be the cause. I am out of ideas to stop the noise.

    Only 300 miles and Canyon has a vibration, actually, it's feels more like one of the front wheels is lose. Dealer says everything is tight and problem is that truck is so light in the back that gives the feeling. Happens at mostly low speeds, 5 - 40. Sure feels like something is wrong to me.
  • I have a light truck and it drives very smooth. Your have to keep going to the dealer and if must have the service manager drive with you and see what he thinks. That is their job. Good luck, Frank P
  • Just wanted to let all of you know that my vibration was coming from inside the exhaust system. Dealer replaced and the vibration is gone and I love it.
  • Check your back tire for bal. first check your back brakes drum be bad good like.

    I have the same problem, 2004 only 20, 000 kms it has been back to the dealer about six times, still vibrates, is yours fixed ?
  • skysteveskysteve Posts: 5
    2004 colorado, 20,000kms I have the same problem, is yours ok now, Steve

    I have a similar problem with my '08 colorado. the problem is traced to the transmission but GM and the dealership refuse to open the trans to isolate the problem. I'm told the the tinniness is the vibration magnified through the hollow drive shaft.

    I think its the exhaust system that makes that noise, GM put an extra clamp on and its a bit better now

    I have this vibration in the exhaust too...GM said this is normal vibration... there engineering must be sitting on there hands...I guess they don't want me to buy another GM product... What dealer did this for you??? And what did they replace???? I paid good money for this truck and I would like it fixed....I tried other canyons some have the problem some don't.....This vibration started soon after I got it... 2000 RPM and above
