Chevy Silverado and GMC Sierra Noise and Vibration

  • Did you ever find out what the noise was i have the same thing on my 2003 4x4 howie10
  • I recently bought an 08 GMC Sierra. I have noticed that it has a vibration and roaring noise coming from the rear of the vehicle when I put it into gear before moving and also when I am accelerating or decelerating at varying speeds. I have read several other posts regarding similar issues, but am unsure as to what to try to explain to the dealer's repair shop when I take it in for this problem. Could someone please give me some real insight into this problem?

    I seem to have a shimmy/vibration when reaching 50miles per hour. Just had the u-joint at the driveshaft replaced. Any suggestions on what this might be?
    Thanks in advance.
  • When you accelerate or decelerate and the truck reaches about 1300-1500 RPM the rear end makes a grinding/vibrating sound (low pitched). It also seems to make when driving steady speeds on the highway. I took the truck in to the dealer's shop and they told me that it was the heat shield on the muffler. The fix was to install a strap over the heat shield to hold it down. They installed it. I drove out of the parking lot with the truck making the same noise, maybe even worse than before. I called them back to let them know that it was doing the same thing. The reply....just bring it in again. I am getting pretty tired of this on a $20,000 truck.
    Has anyone else had this type of problem?
  • A while back I posted that I was getting a squealing/chirping noise on my '02 1500 4x4. I figured it was the brake pad squealer as I just bought the truck in December. Took all the wheels off today finally, and all the pads are worn evenly and still have about 3/8" left. So the pads aren't worn down. The chirping is speed dependent and never turns into a continous squeal up to about 45 mph, which is where I can't hear it anymore. If I'm going 25-30mph and it's chirping, if I put on the brakes lightly it seems to go away (although it's replaced by brake squeal). I tried shooting brake cleaner on all the pads/rotors today and this made no difference but to quiet the brake squeal down some. My Dad rodei n the back and hung over the rear wheels and said it sounded the same from both sides. The front wheels seemed tight, there was a little play in the rear wheels, but you had to really hoss on the wheel to feel it. Any suggestions onwhere to look next?
  • Had to take the truck out of state for several days and on the drive back the squeaking got worse. Took it to a shop this morning and they said the rear axle is slightly bent causing the hub to wobble and the brake pads to hit and squeak. Great.....$540 + tax.

    I have a 2000 GMC Sierra Z71, Ext cab, 4wd, 5.3, 174k with front end vibration from 45-65 mph. It feels like a broken belt in the tire. Tires have been rotated to all 4 corners with no change. There is some side to side play in the left front but none up and down. The lower ball joint has a little movement as well. The right side is tight, no problems. Could it be a wheel bearing? Any thoughts are greatly appreciated.

    When rotating the tires, were they balanced?
  • 1truck1truck Posts: 8
    They were balanced when they were new 3 months ago and again last week. When they did them last week, they were still ok, didn't need any changes to the weights.

    Vibration at 45-65 is almost always tire related. While a bearing or tie rod may cause an alignment issue and eventually vibration due to uneven wear. If your tires check out ok I'd seriously question the tire shop. What I would recommend is finding a tire dealer who has a Hunter GSP9700 balancer and have them check out the balance on the tires.

    Problem solved. Found 2 rear u-joint clips were missing, had some of those so no expense. That fixed most of the vibration. Still had some vibration in the steering. Both lower ball joints need replaced, $940. Better than a truck payment. Thanks for your help!

    I have a 99 Siverado with the 4.8l engine. From 62 to about 68 mph I get a terrible vibration. If I stay on either side of those speeds it rides fine! I was thinking of dropping the driveshaft and having the balance checked. I have had the all of the tires balanced. Any suggestions would be deeply appreciated!
  • obyoneobyone Posts: 8,065
    Before doing that try shifting to neutral at 65 mph on a straightaway. If the vibration stops you've found the problem.
  • i have a 2002 sierra z71 4x4 also and i am having a bad grinding noise coming from right rear wheel. at 15 to 40mph when you hit a bump a clinging noise sounds like metal on metal and now there is a grinding noise that is very loud. i have taken it to a shop and 1000.00 later the problem is still there. i had several things wrong with truck that the shop thought would be causing problem. i replaced exhaust that was broken, rear shocks, front pads, repacked front wheel bearings, replaced transmission mount, and front rotors. noise and grinding is still there. today shop removed right rear e brake pad and thought it was cleared up, guess what drove truck away from shop and noise is still there and now grinding is more often. unknown if wheel bearings is bad or axel is bent something is grinding and is costing alot of money to figure out. luckly i found a great shop that is trying very hard to fix problem. any suggestions would be appreciated
  • i have an 02 sierra z71 4x4 that is doing the same thing but on the right rear. i have not had any luck getting it fixed. let me know what you find PLEASE...... i will do the same

    i replaced exhaust that was broken, rear shocks, front pads, repacked front wheel bearings, replaced transmission mount, and front rotors. noise and grinding is still there. today shop removed right rear e brake pad and thought it was cleared up

    If the noise came from the rear, why was the front pads changed and the front wheel bearings replaced? Did anyone check the rear brake? How long since servicing the rear end? Those rear rotors have been known to lock up causing major noise from the rear.
  • I am confused, with max AC selected on, I hear what sounds like the engine fan rubbing during heavy acceleration and just coming off the acceleration. Fan tips seem to be worn, but good clearance around fan shroud with engine turned off. I do not witness any severe engine movement during acceleration or deceleration. Noise will occur in "park" or when driving. Water pump changed last year, everything appears normal. Belt tension & wear normal. AC blows cold. I was thinking of the following possible causes: broken motor mount (don't see motor sway), fan clutch, ac compressor, or harmonic balancer. It is difficult to confirm with engine rpm around 2500-2900 rpm on quick accel or decel.

    Has anyone seen this before or have any input?
  • Lube your Leafs! Spread each leaf and spray heavy lube on the little pads between each leaf. I also took out leaf spring mount bolts as far as possible and lubed inside their bushing too. There is a TSB out there about replacing the leaf pads with teflon material pads.Hope this helps!

    Have a 09 GMC Sierra. Several months ago started feeling two distinct vibrations coming from the gas pedal shortly after putting it in drive and starting to pull away. After this you won’t feel the vibrations again until the truck has been put into park again and shut off for a few minutes. The speed that I pull away at doesn’t seem to be a factor and it won’t do it in reverse. Been to the shop numerous times and each time they call it “normal operation” except that it didn’t do it when I bought it 6 months ago. Any ideas?

    IM SURE ITS THE VAC PUMP NOISY GROWL AT FRONT OF ENGINE BELOW SPRING TENSIONER ON LEFT FACING FRONT END.WILL IT RUIN ANYTHING AS FAR AS PERFORMANCE OR MILEAGE
  • I too have this problem with my truck, the noise is not continuous nor is it predictable, and seems to come from the front of the truck. Seems to only do it while moving. I still have not seen a solution to this yet but hope someone will find it soon. The sound of "the tire was rubbing the fender" caught my attention and sounded very similar to mine. I have a 06 silverado 4x4 reg cab lwb.
    Also, friend of mine at work owns an 03 model and says his started doing the same thing as well, we are both clueless so far.....thought maybe steering box or wheel bearings.
  • Can anyone tell me where the knock sensor is located on a 2000 GMC Sierra 1500, 5.3 and is it easily replaced? The dealer checked the code for the "service engine soon" light and said it is bad and will eventually cause it not to start. I lost my repair manual for the truck. Thanks!
  • obyoneobyone Posts: 8,065
    Knock sensors are located between the fuel rails on the top of the engine.

  • Well, truck had another sound coming home from work one morning, sounded like absent brake pads but wasn't applying them, seen bad upper A arm bushing while investegating but had everyting suspension-wise checked out, found out bushing was bad but also had driver side wheel bearing going bad. I hope this cures all but if not, will post back again
    Thanks,

  • just purchased a 2001 silverado 4x4 4.8 v8 with 60k. it shifts great, but when i took it upsate, the first incline i hit, it slows down a little then I started to hear this squeeling metal bending type noise. when i aplly some pressure to the pedal it shifts normally, I ease up on it and squeeling noise comes back all through the incline., went to get a 60k check and they said its flawless ( no leaks, discoloration, rust anything). the last owner used it for commuting, and slight vacation camper towing...thanks
  • i have a 2007 chevy silverado 4x4 reg cab and it is making the same noise (sounds like tire rubbing but i am stoped) . did you find out what is causing the noise.
  • This is the infamous lifter tap.. you may have to replace the lifters, which isn't cheap. I replaced my first set on my '02 at 38k mi and the second set at 138k mi. I replaced mine with performance lifters, wasn't cheap but it resolved the issue.
