B-pillar Posts Get Fixed End Of This Coming Week

[jrrod2004]

Its a 4WD, and I have tried closing that thing tighter a million times. It seems to be coming from the midgate region, not necessarily the midgate itself. I'm not sure what it is, but it is dang sure annoying.

 

They may have to adjust it to make it close tighter

Are there any bulletins for the A-pillar?

 

I've already had my driver's side replaced once. It's peeling off the metal again.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

 

Condition/Concern:

Some owners may comment of a wind noise or excessive gap between the front door and "A" pillar molding. This concern could be noticed at either the left or right front door.

 

Recommendation/Instructions:

 

1. Measure the gap between the reveal molding and the edge of the door 25 mm down from the top of the reveal molding (see picture).

   

    

    

2. If the gap is greater than 7 mm, proceed with the following repairs.

    

3. Replace and secure all door side bolts with service bolt part # 11609733 (one bolt at a time). These are the bolts attaching the hinge to the door.

    

4. Loosen the upper hinge bolts and pull the top of the front door header in towards the cab while tightening the top hinge bolts. Close the front door and recheck the gap as per step 1 and if the gap is still 7 mm or greater continue to the next step.

    

5. Support the door, loosen all door side bolts and lower the door by 1mm and pull the door header inboard while pushing the bottom outboard. While holding the door in this position have someone else tighten the hinge bolts. Close the front door and recheck the gap as per step 1 and if the gap is still 7mm or greater continue to the next step.

    

6. Remove the reveal molding and install nylon washers behind the reveal up against body in the area shown below. This will space the molding closer to the door edge, but still have at least a 2 to 3 mm overlap of the glass.

   

    

    

7. An additional item that can be completed is to install foam between the body and weather strip as shown below.Note: View to ensure it looks good from a front view with the door closed.

    

 

 

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

 

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

X2, Mine started doing this around October. Just drivers side. More of a rattle than creaking and it only does it over bumps, uneven pavement.

I have the extended cab 2010 and ive finally found the rattle/ squeak that has begun that drives me absolutely nuts when driving down the slightest bumpy road is the b pillar interior moulding that you can pull off, just held in by tabs. the right hand side of the thing has no clips just the left side and to my understanding the right side of it is rubbing against the metal and making the most irritating noise ever! anybody have a fix?
