Jeep Liberty KJ. Manual — part 1276
POSSIBLE CAUSE OF WIND NOISE
•
Moldings standing away from body surface can catch wind and whistle.
•
Gaps in sealed areas behind overhanging body flanges can cause wind-rushing sounds.
•
Misaligned movable components.
•
Missing or improperly installed plugs in pillars.
•
Weld burn through holes.
STANDARD PROCEDURE
STANDARD PROCEDURE - BODY LUBRICATION
All mechanisms and linkages should be lubricated when necessary, except the door check straps and latches. This
will maintain ease of operation and provide protection against rust and excessive wear. The weatherstrip seals
should be lubricated to prolong their life as well as to improve door sealing.
All applicable exterior and interior vehicle operating mechanisms should be inspected and cleaned. Pivot/sliding con-
tact areas on the mechanisms should then be lubricated.
1. When necessary, lubricate the operating mechanisms with the specified lubricants.
2. Apply silicone lubricant to a cloth and wipe it on door seals to avoid over-spray that can soil passenger’s cloth-
ing.
3. Before applying lubricant, the component should be wiped clean. After lubrication, any excess lubricant should be
removed.
4. The hood latch, latch release mechanism, latch striker, and safety latch should be lubricated periodically.
5. The door lock cylinders should be lubricated twice each year (preferably autumn and spring).
•
Spray a small amount of lock cylinder lubricant directly into the lock cylinder.
•
Apply a small amount to the key and insert it into the lock cylinder.
•
Rotate it to the locked position and then back to the unlocked position several times.
•
Remove the key. Wipe the lubricant from it with a clean cloth to avoid soiling of clothing.
6. Door and swing gate check straps should be wiped clean but not lubricated.

HEAT STAKING
1. Remove trim panel.
2. Bend or move the trim panel components at the heat staked joints. Observe the heat staked locations and/or
component seams for looseness.
3. Heat stake the components.
a. If the heat staked or component seam location is loose, hold the two components tightly together and using
a soldering gun with a flat tip, melt the material securing the components together. Do not over heat the
affected area, damage to the exterior of the trim panel may occur.
b. If the heat staked material is broken or missing, use a hot glue gun to apply new material to the area to be
repaired. The panels that are being heat staked must be held together while the applying the glue. Once the
new material is in place, it may be necessary to use a soldering gun to melt the newly applied material. Do
not over heat the affected area, damage to the exterior of the trim panel may occur.
4. Allow the repaired area to cool and verify the repair.
5. Install trim panel.

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.

PLASTIC BODY PANEL REPAIR
There are many different types of plastics used in today’s automotive environment. We group plastics in three dif-
ferent categories: Rigid, Semi-Rigid, and Flexible. Any of these plastics may require the use of an adhesion pro-
moter for repair. These types of plastic are used extensively on DaimlerChrysler Motors vehicles. Always follow
repair material manufacturer’s plastic identification and repair procedures.
Rigid Plastics:
Examples of rigid plastic use: Fascias, Hoods, Doors, and other Body Panels, which include SMC, ABS, and Poly-
carbonates.
Semi-Rigid Plastics:
Examples of semi-rigid plastic use: Interior Panels, Under Hood Panels, and other Body Trim Panels.
Flexible Plastics:
Examples of flexible plastic use: Fascias, Body Moldings, and upper and lower Fascia Covers.
Repair Procedure:
The repair procedure for all three categories of plastics is basically the same. The one difference is the material
used for the repair. The materials must be specific for each substrate, rigid repair material for rigid plastic repair,
semi-rigid repair material for semi-rigid plastic repair and flexible repair material for flexible plastic repair.
Adhesion Promoter/Surface Modifier:
Adhesion Promoters/Surface Modifiers are required for certain plastics. All three categories may have plastics that
require the use of adhesion promoter/surface modifiers. Always follow repair material manufacturer’s plastic identi-
fication and repair procedures.
SAFETY PRECAUTION AND WARNINGS
WARNING:
•
Eye protection should be used when servicing components. Personal injury can result.
•
Use an OSHA approved breathing mask when mixing epoxy, grinding, and spraying paint or solvents in
a confined area. Personal injury can result.
•
Avoid prolonged skin contact with resin, petroleum, or alcohol based solvents. Personal injury can
result.
•
Do not venture under a hoisted vehicle that is not properly supported on safety stands. Personal injury
can result.
NOTE:
•
When holes must be drilled or cut in body panels, verify locations of internal body components and elec-
trical wiring. Damage to vehicle can result.
•
Do not use abrasive chemicals or compounds on undamaged painted surfaces around repair areas. Dam-
age to finish can result.
