Check this out - our dealerships(s) would not do it but maybe you will have some luck. Know we have newer models but looks like it could id exactly where the vibration is coming from - was thread #101 I think.
Models:2007-2008 Cadillac Escalade, Escalade ESV, Escalade EXT
2007-2008 Chevrolet Avalanche, Silverado, Suburban, Tahoe
2007-2008 GMC Sierra, Yukon, Yukon XL
with any of the following Tire RPO's:
- QSS (P275/55R20)
- QXT (LT265/70R17)
- QST (P285/45R22)
- QIZ (LT245/75R16)
- QAS / QAN (P265/70R17)
- QJM / QJP (P265/70R17)
Attention: Proceed with this bulletin ONLY if the customer has commented about this concern AND the EI number is listed in GMVIS. If the customer has not commented about this condition or the EI does not show in GMVIS, disregard the bulletin and proceed with diagnostics found in published Service Information. THIS IS NOT A RECALL -- refer to Service Bulletin 04-00-89-053A for more detail on the use of Engineering Information bulletins.
This bulletin is being revised to add tire RPOs QST, QIZ, QAS, QAN, QJM and QJP. In addition, step 11 has been revised to request the 11-digit DOT number of the tire. Please discard Corporate Bulletin Number 07-03-10-013 (Section 03 -- Suspension).
Some customers may comment on a vehicle/tire vibration.
GM Engineering is attempting to determine the root cause of reported tire vibrations on vehicles equipped with P275/55R20, LT265/70R17, P285/45R22, LT245/75R16 or P265/70R17 tires. GM has a need to obtain information during diagnosis and BEFORE repair. This information will be used by engineering to "root cause" the customer's concern and develop/validate a field fix.
If the customer's concern can not be duplicated -- disregard this bulletin. If the customer's concern can be duplicated, complete the following steps. Be sure to note the following information on the repair order:
Verify that the VIN and mileage listed on the repair order is accurate. Describe the customer's concern (i.e. shake, buzz, roughness, tingling). Note when (mph, idle, accel, decel, etc) and where (steering column, seat, etc) the vibration is felt. Document the tire size and manufacturer of the tires currently on the vehicle. Inspect the following components to verify that they are in good working condition. Note any "faults" on the repair order:
• tire/wheel assemblies
• steering components
• suspension components
Install the J 38792-A (Electronic Vibration Analyzer -- EVA) sensor to the component identified by the customer as the most respondent to the vibration. If no component was identified, install the J 38792-A sensor to the steering column. Select a smooth, level road and slowly accelerate the vehicle up to highway speed. Observe the vehicle for disturbances that match the customer's description and note the following conditions:
• Vehicle speed
• Engine RPM
• Transmission gear range and specific gear
• Vibration frequency reading, detected by the J 38792-A
If the sensor was originally placed on the steering column, and the vibration seems to excite a particular component of the vehicle more than the steering column, move the J 38792-A sensor to that component and repeat steps 6 and 7. Does the frequency data clearly fall within the tire/wheel parameters? (Refer to Symptoms -- Vibration Diagnosis and Correction, found in SI).
• NO -- continue to diagnose and repair the vibration not related to the tire and wheel assembly. • YES -- proceed with Step 10.
Using the HUNTER GSP9700 Roadforce/Balancer, measure the roadforce variation of each tire/wheel assembly. Also, with the original balance weights still installed, measure the inboard and outboard imbalance. Record the findings on the RO. Record on the repair order, the 11-digit DOT number found on the rim flange of the tire.
PRIOR to making any repairs, contact the engineer listed below with information from your diagnosis. The engineer will provide direction to repair the customer's concern. For vehicles located in SE Michigan, the engineer may need to physically inspect the vehicle
#132 of 195 Tahoe avalanche vibration
Nov 20, 2011 (7:24 am)
Thanks Stan 99 and brycourt I bought a 2011 avalanche ltz loaded 4 days ago 31 miles. Next day on the interstate from 60-80 started to get pretty substantial vibration sterringwheel shaking took back for balance and alignment next day over 60 same thing called again spoke with svs manager asked if he has been having a similar problem? He said some times tire will have flat side from sitting on lot? They drove and found nothing out of the ordinary vibration I guess these clowns drive washing machines to work! My last 4 vehicles have bee gm envoy, gmc Yukon,Tahoe ltz all brand new never had vibration issues. So Friday I made my annual pilgrimage to ohio from sc to see the outllaws for thankgiving noticed the vibration starts 60 comes in intervals every 15-20 seconds last for 25-30 seconds goes away and comes back again? worst 10 hour ride of my life 600 miles now going to dealership in Columbus mon. Any suggestions?

I'm sorry that this vehicle concern interfered with your Thanksgiving trip. Would you be willing to email us more details so we can further check into your vehicle's information? Please include your name/username and the last 8 digits of your VIN.

#134 of 195 Tahoe Vibration
Nov 26, 2011 (3:01 pm)
This is an update to my post on March 01, 2008 concerning vibrations between 65 - 75 MPH with my Goodyear 17" tires. Dealer re-balanced tires twice, and each time the vibration got better (lower vibration) but still objectionable, indicating to me it was a tire problem. On the third time back to the dealer, he said he could not duplicate the problem and did nothing, a cop-out way to give up. Due to pressing family problems at the time, I did not pursue further with GM to change tires, so I just put up with the vibration which was manageable at 75 MPH. Now with 30,000 miles on the tires and one making noise, the vibration is more managable as the tires wear, and I drive above the speed were it starts to vibrate. When it reaches 40,000 miles, I will change to Michelin tires which have a better history for smooth ride at speed. I wish GM would offer an option for Michelin tires when buying the vehicle new from the dealer.
#135 of 195 2009 Suburban Vibration

I have developed a rear end vibration between 70-85MPH after haveing new rear brakes and turning rear rotors. I returned to the Goodyear Tire Store (Very Reputable). To eliminate anything they may have done they first balanced all four tires. When this did not work they replaced the rear roters at their cost. Still vibration. They put on a brand new set of tires re balanced. Still not resolved. They owner of the store has a 2010 Youkon XL. He put his tires and wheels on my Suburban and still vibrates. They feel they have done everything that would point at tires,brakes and rotors. I have read about vibrations on Tahoe's and Suburbans. What is the next thing to check in the drive train?

Check the vibration in the heads of G.M. execs!
Sorry for joking, but almost every vehicle they produce has a serious flaw.
Our premier U.S. company has become obsolete, and only aggravates its customers. ( "nothing wrong with your car, they all do it")
#137 of 195 Vibration Hunting
Dec 19, 2011 (9:09 pm)
Google 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 (98 Silverado), 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 rolled off the factory floor with out of phase drive lines. W...tf?
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.

They had to replace the rear end of my Tahoe but that did not fully fix the problem I say do the lemon law.

It's not the tires it the vehicle!!! GM needs to fix it or do the lemon law.
