Subject:EI07266 - Vehicle/Tire Vibration, P275/5R20, LT265/70R17, P285/45R22, LT245/75R16, P265/70R17 #07-03-10-013A - (11/01/2007)

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

Thank you Edmunds for allowing us to network our agravations on brand new GM products. If GM hired the same amount of Quality Control people as they do "customer service" they might build a vehicle worth owning! I predict the company will be out of business (again) in 5 years. If you think the Tahoe lines have problems, check out the GMC Acadia platforms. Terrible. And to watch the secrecy and oblivion and run around after the sale is just pathetic.

Chevrolet Tahoe Vibration Problems, it's been over a year now since I brought my Tahoe. If I could trade it in and get the pay off for it I would. I will never own a Chevrolet again as long as if live. Actually any GM car. So if you're thinking of buying one look at Edmunds.com to make a intelligent decision. I still have the vibration. Chevrolet is going under again, and I hope all of GM with it.

Have you spoke with a dealer or Customer Assistance? Can you please provide your VIN? I look forward to your response.

Are you still on the original tires? You may want to swing by a tire shop for an evaluation and perhaps rebalancing or an alignment.

Yes. The dealer had to replace all four tires. It took them a few days to find four tires of equal weight. Make sure you make them do a forced balance on the tires.

Saw the vibration messages and I am struggling with a 2010 Suburban LTZ we bought new about a year ago. Has been looked at by Freedom Chevrolet in San Antonio and has two new sets of tires on it and it has not resolved the vibration appearing to come out of the rear of the truck - any assistance would be GREATLY appreciated as I am at wits end with this 50K+ truck. Currently has the 20" Chevrolet rims and the higher end Michelin LTX tires put on last week.
About an inch away from submitting a Lemon Law claim on the vehicle.
