Tink-tink Noise In Roof/winshield Area At 65-70 Mph

FredCWO · January 1, 2008

I'm experiencing this noise (tink-tink) type noise at interstate speed. I can't have the only new body stlye GMC that has this? I think I'm going to make an appointment next week to have it checked out at the dealership. I think it might have something to do with the seal between the top of the glass and the roof, but it doesn't leak.

Fred,

I saw this in another post about this same problem. It seems from those posts the the seal around the top left and right side of the windshield loosen while going down the highway. The consensus from some of the members is that its from the bud deflector which may cause this. It may have something to do with aerodynamics?!

One of the options is to use some two way tape to button down those seals around the windshield.

John,

Are you a USCG instructor? I'm also in the USCG if so.

Anyways, I would like to think GM would have a fix if I were to take it in for this apparent problem.

Fred,

I sent you a message.....

Truckin2003 · January 1, 2008

looks like you have a bug shield on the front there. i put one on my truck for less then a day when i had to pull of the side of the road and take it off because it was annoying me so bad. the wind deflect right to the top of the window and rattles the window molding.

many people have fixed it by putting silicone around the edges of the molding or something to that effect.

jrrod2004 · January 1, 2008

Yep, sorry I went out for new years.........that deflector could be what is causing it......in addition, you have three tsbs on your truck's GMVIS profile..... EI

Attention: Proceed with this bulletin ONLY if the customer has commented about this concern AND the EI number is listed in GMVIS, otherwise disregard the bulletin and proceed with diagnostics found in the 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 the 2008 model year and update the information. Please discard Corporate Bulletin Number 07-02-32-002B (Section 02 -- Steering).

Condition

Some customers may comment on a fluid leak. Upon investigation, the technician may find fluid leaking from the power steering system.

What Action to Take

Important: All potential leaks should be completely cleaned and identified before attempting to repair or replace any power steering components.

Start diagnosis by inspecting the fluid level in the Power Steering Reservoir. If the fluid level is NOT low, a careful analysis of the condition is necessary as it may involve a different type of fluid leak.
Visually inspect the components where the fluid has accumulated.
Completely clean off any fluid residue from the suspect components.
Apply tracing powder to the suspect components. This is an effective way to determine the source of a leak. As an alternative, fluorescent dye (such as Kent Moore J 28431-6) may be added to the power steering fluid.
Start the vehicle and allow the power steering system to reach normal operating temperatures.
Turn the steering wheel to the stops in each direction while bumping the steering wheel against the stops 3-4 times. This will build maximum steering system pressure and help identify the source of the leak if present.Tip
A black light may be used with yellow safety glasses to help pinpoint the source of a leak.
Determine the source of the leak.
If a repeatable leak is found, use the following tables to determine if the condition is repaired and what corrective action is needed.

Repairable Leaks

Source of Leak

Correction

Pressure feed and return hoses/lines

Replace seals, hose, or line set

Power steering pump

Reseal or replace pump if necessary

Cylinder gear/rack lines

Replace O-ring seals or rack lines

Non- Repairable Leaks

Source of Leak

Correction

Porosity leak in the gear/rack housing

Replace steering gear/rack

Leak from tie rod boots

Pinion seal

Repeatable leak at steering gear adjuster plug*

See note below

*If fluid is observed at the adjuster plug during the initial visual inspection, then refer to the following:

• Seepage at the adjuster plug may not necessarily indicate an active leak. Power steering fluid is used during the manufacturing of the gear/rack. The fluid used at assembly is pushed into the pinion area during assembly. The adjuster plug and the area below the pinion are not positively sealed. Fluid trapped in this area during assembly may seep from the adjuster plug. The rack should not be replaced for this condition.

• You can distinguish seepage from an active leak by removing the left tie rod boot clamp and inspecting for the presence of fluid at the inner tie rod.

• If no fluid is found in the left tie rod boot, replace the boot clamp and clean the seepage from the rack. No further action is needed.

• If fluid is found in the left tie rod boot, replace the gear assembly.

Engineer Contact Information

You may contact Engineer Tim Emmitt at 586-492-0278 for additional information or guidance before repairing the vehicle. This call may result in a personal visit to your dealership or a special request to return parts that exhibit unique conditions. In either case, you should receive a response back within 2 hours on what action to take the same business day of your call (Eastern Daylight Time).

If you do not receive a response from engineering, then proceed to repair the vehicle. Use normal diagnostics and claim the repair work under the appropriate warranty labor operation.

GM Engineering is working to determine the root cause of the above conditions. GM Engineering has a need to obtain information during diagnosis and BEFORE repair. As a result, this information will be used by engineering to "root cause" the customer's concern and develop/validate a field fix.

Hope this additional info helps if you are having more than just the tink noise in the roof/windshield area.........

FredCWO · January 1, 2008

I guess it wouldn't end up bothering me so much if I hadn't bought the bug deflector from GM..

Anyways, I guess I'll throw a bead of silicone around the top of the windshield.

I appreciate the informed help and hope you all had a happy New Year.

Been reading posts my new style Silverado has the samr rattle from same area. Doesnt do it all the time. I think wind direction plays a role.

Also mine made the noise before I added bug deflector or visors

Hello. I have had this on my old 2005 Silverado, on my new 2007 Sierra, and my wife's 2007 Tahoe and her old 2002 Trailblazer. The dealer told me that it was my bug guard (Which was incorrect as it did it even after I took it off). They told me this on all three of these vehicles, probably because they hate to troubleshoot rattles and it is easier to blame someone elses product than their own. They actually fixed it on the trailblazer but all that they did is remove the trim and re-stick it down.

Here is my fix, it worked on all of the vehicles above. Clear silicone caulking. Running along the glass on the "A" Pillars there is a piece of trim about an inch wide. That is what is making the noise. Run a bead of caulk below the trim so that it contacts the glass as well as the trim.

Hope that helps.

Thanks for posting this. Both of my back door panels (crew cab) are loose. I haven't had to bring my truck back to the dealer yet, but when I do I will be sure to mention this TSB.
