Jeep Grand Cherokee WK. Manual — part 1588
PANEL PATCH INSTALLATION
1. Make a paper or cardboard pattern the size and
shape of the cutout hole in the panel.
2. Trim 3 mm (0.125 in.) from edges of pattern so
patch will have a gap between connecting sur-
faces.
3. Using the pattern as a guide, cut the patch to size.
4. Cut scrap pieces of patch material into 50 mm (2
in.) squares to use as patch supports to sustain the
patch in the cutout.
5. Drill 4 mm (0.160 in.) holes 13 mm (0.5 in.) in from
edge of cutout hole.
6. Drill 4 mm (0.160 in.) holes 13 mm (0.5 in.) away
from edge of patch across from holes drilled
around cutout.
7. Drill 3 mm (0.125 in.) holes in the support squares
13 mm (0.5 in.) from the edge in the center of one
side.
8. Scuff the backside of the body panel around the cutout hole with a scuff pad or sandpaper.
9. Mix enough adhesive to cover one side of all support squares.
10. Apply adhesive to cover one side of all support squares.
11. Using number 8 sheet metal screws, secure support squares to back side of body panel with adhesive sand-
wiched between the panel and squares.
12. Position patch in cutout against support squares
and adjust patch until the gap is equal along all
sides.
13. Drill 3 mm (0.125 in.) holes in the support squares
through the pre-drilled holes in the patch.
14. Apply a coat of adhesive to the exposed ends of
the support squares.

15. Install screws to hold the patch to support
squares. Tighten screws until patch surface is
flush with panel surface.
16. Allow adhesive to cure, and remove all screws.
17. Using a 125 mm (5 in.) 24 grit disc grinder, grind
a 50 mm (2 in.) to 75 mm (3 in.) wide and 2 mm
(0.080 in.) deep path across the gaps around the
patch. With compressed air, blow dust from
around patch.
18. Apply adhesive backed nylon mesh (dry wall tape)
over gaps around patch.
19. Mix enough adhesive to cover the entire patch
area.

20. Apply adhesive over the mesh around patch, and
smooth epoxy with a wide spreader to reduce fin-
ish grinding. Use two to three layers of mesh and
adhesive to create a stronger repair.
PATCHED PANEL SURFACING
After patch panel is installed, the patch area can be finished using the same methods as finishing other types of
body panels. If mesh material is exposed in the patched area, grind surface down, and apply a coat of high quality
rigid plastic body filler. Prime, block sand, and paint as required.
BUZZ, SQUEAK & RATTLE
Buzz, Squeak & Rattles (BSR) may be caused by any one or more of the following and may be corrected as indi-
cated:
•
Loose fasteners should be tightened to specifications.
•
Damaged or missing clips should be replaced.
•
Damaged trim panels should be replaced.
•
Incorrectly installed trim panels should be reinstalled properly.
Many BSR complaints such as loose trim, can be serviced using the Mopar
T
Parts BSR Noise Reduction Kit. This
kit contains various tapes including foam, flock and anti-squeak used to eliminate noises caused by metal, plastic
and vinyl components. Long life lubricants and greases can also be used on a variety of components. Refer to the
Buzz, Squeak & Rattle Kit table for material contents and usage.
