Condition Some customers may comment on hearing excessive wind noise coming from the front
side door glass area.
Cause The cause of the condition may be any of the following three primary factors:
Page 2 August, 2017 Bulletin No.: 17-NA-258
3806381
• Improper front side door fit to roof.
4846275
Bulletin No.: 17-NA-258 August, 2017 Page 3
4846276
• Incorrectly installed front side door window weatherstrip.
• Wind noise generated from sheet metal openings in the upper door frame.
Correction
Note: In cases where the noise can’t be verified coming from the door, and may be
coming from the rear cab area, see Bulletin #17-NA-151.
Verify the condition and repair following the steps outlined in the Service Procedure
below.
Service Procedure
3806384
Note: These vehicle models use an inlay door
construction, with the door fitting sub-flush to the body
header by 1-2mm (0.040–0.080 in).
3806385
1. At the two locations (1) shown in the illustration
above, inspect the front door fit as to meeting the
suggested 1-2mm (0.40–0.80 in) sub-flush
dimension.
• If the door fit meets the sub-flush specification,
no door adjustment is necessary and you can
jump ahead to step #4.
• If the door fit DOES NOT meet the sub-flush
specification, continue to step #2 to start the
door adjustment.
Page 4 August, 2017 Bulletin No.: 17-NA-258
Important: The door header bending procedure is only
suggested for technicians experienced in finessing
sheet metal fits.
2. In conditions where the door header is
outboard the design intent, a 1-2 mm (0.040–
0.080 in) change may be accomplished by bending
the door header inboard.
2.1. Lower the front side door glass.
2.2. Placing one hand at the belt and the other at
the door header, carefully attempt to bend the
door about the belt.
2.3. Recheck the door fit to the body header.
3806388
Note: The referenced hinge service bolt (2) is
non-shouldered and will allow more adjustment than
the original shouldered bolt (1).
3. If bending the door header does not resolve the
condition, the door fit must be adjusted by adding
two hinge service bolts, P/N 11561763.
3806391
Important: Do NOT touch the body side hinge bolts or
the door side lower hinge, lower bolt.
3.1. Remove both door side upper hinge bolts (1).
3806392
3.2. On the lower hinge, loosen the door side
upper bolt (1).
3.3. Replace both door side upper hinge bolts with
service bolt P/N 11561763.
3.4. Tighten the new bolts while applying inboard
pressure to the door.
Tighten
Tighten the bolts to 25Y(18 lb ft).
3.5. Verify the door fit and tighten the remaining
bolt. Verify proper torque on all four door side
hinge bolts.
4846278
4. Remove the front door trim panel, garnish molding,
outside rearview mirror and belt reveal molding.
Refer to Front Side Door Window Belt Reveal
Molding Replacement in SI.
Bulletin No.: 17-NA-258 August, 2017 Page 5
4846279
5. Remove the front window inner sealing strip, front
window, and the front window weatherstrip. Refer
to Front Side Door Window Weatherstrip
Replacement in SI.
4846281
6. Inject Kent® Ure-Foam Expandible Foam Sound
Deadener # P10630, or equivalent, into the metal
glass run channel of the upper door frame by
following the steps below:
4846283
6.1. To help contain where the Kent Foam Sealer
will be injected, tape off two areas (1) around
the top of the metal door glass run channel
openings. One near the top of the mirror
shark fin, and the other at the top of the
B-pillar.
4846284
6.2. Inject Kent Foam Sealer into both metal glass
run channel openings and quickly tape over
the injected holes to help contain the sealer.
6.3. Wait approximately 10 minutes to allow the
foam to dry then remove all of the tape.
Page 6 August, 2017 Bulletin No.: 17-NA-258
4846285
6.4. Scrape/cut out all excess foam to enable the
rubber glass run channel to be reinstalled with
no interferences.
4846287
6.5. Using Kent® High Tech Clear Seam Sealer P
10200, or equivalent, add/brush seam sealer
to the door pinch weld flange to totally seal
the door outer and inner sheet metal at the
top of the door header.
Bulletin No.: 17-NA-258 August, 2017 Page 7
4846288
6.6. Let the seam sealer dry for approximately 10
minutes, then clean with *3M Adhesive
Remover, or equivalent, to remove any
excess residue.
4846289
6.7. Inspect the upper door frame metal glass run
channel, just forward of the B pillar, for
possibly being out of design location.
• If the metal run channel is approximately
the same depth across the top (1), no
additional repair in this area is needed, and
you can move ahead to step # 8.
• If the metal run channel is approximately
1.5 mm higher (up/down) (2), continue to
step # 7 to add foam tape.

4846290
7. Obtained locally, add a 2 mm thick foam shim to
prevent the rubber glass run channel from getting
installed too deep. The approximate location is
shown in the graphic above.
Note: The graphics below are “before and after”
examples which help show the proper positioning
of the front door window weatherstrip.

Important: The last example above shows the front,
upper corner of the weatherstrip installed too high and
well out of position. The feature line (shown circled)
should be located down at the center-line of the metal
notch.
Page 10 August, 2017 Bulletin No.: 17-NA-258
4846296
Note: Applying GM Glass Cleaner, P/N 19287404
(Canada P/N 8865156), or even plain water, to the
weatherstrip will allow the part to slide and be
re-positioned more easily during installation.
8. Reinstall the front window inner sealing strip, front
window, and the front window weatherstrip. . Refer
to Front Side Door Window Weatherstrip
Replacement in SI. AND ALSO utilize the
additional detailed steps below.
8.1. Position the weatherstrip to the door frame
and insert the front A-pillar leg down into the
window opening of the sheet metal.
4846299
8.2. Starting at the B-pillar upper corner, position
the corner locator (1) on the weatherstrip to
the hole in the sheet metal (2) and push until
locator snaps into place. An audible click
should be heard when the locator engages.
Tip: Check to verify the weatherstrip is securely in
place by lightly pulling down on the rear leg, and
looking for any movement at the upper corner.
8.3. Fully seat the weatherstrip into the door frame
at least a hand-width forward AND downward
from the B-pillar corner.
Bulletin No.: 17-NA-258 August, 2017 Page 11
4846302
8.4. Moving to the A-pillar, match the corner radius
of the weatherstrip (1) to the door frame
radius (2), and push into position.
4846303
8.5. With front and rear corners in place, starting
at the front, fully seat the weatherstrip into
position in the door frame header.
Tip:
With the weatherstrip legs still loose, any gapping at the
header can be adjusted by slightly pulling down on
the legs.
8.6. Once the header is in proper position, fully
seat the weatherstrip at the rear of the door
frame.
4846306
8.7. Return to the A-pillar and fully seat the front of
the weatherstrip down into the window
opening. Ensure that the larger front lip is
positioned outside the sheet metal.
4846308
8.8. As a final position check from inside the door,
ensure the B-pillar upper corner tab of the
weatherstrip is centered to the corner of the
upper door frame. The weatherstrip should
also display a uniform, one to one fit along the
complete perimeter of the door frame.
