Attachment III - Technical Information
LIFTGATE GLASS BALL STUD BRACKETAFFECTED VEHICLES:
CERTAIN 2002 MODEL YEAR EXPLORER AND MOUNTAINEER
OVERVIEW
The affected vehicles will require inspection of the liftgate glass ball stud bracket for proper orientation.
You will also be required to check and tighten the bracket to correct specification. If a bracket is found out of position, you will be instructed to apply Threadlock, reposition the bracket, and tighten it to specification. The specified Threadlock must be used. Torque on the bracket bolt is critical for proper clamp load.
WARNING
TO PREVENT PERSONAL INJURY, WEAR SAFETY GLASSES AND GLOVES WHEN WORKING WITH GLASS ATTACHING COMPONENTS.
INSPECTION
1. Open liftgate glass.
2. Place a straightedge against the inner edge of each ball stud bracket. Measure the distance between the edge of the glass and the straightedge at the lower corner of each ball stud bracket. See Figure 1.
a. If the distance measured is between 43 and 52 mm, the bracket is positioned properly and will only require the following tightening procedure:
^ Tighten (counterclockwise) the attachment bolt with a T-30 Torx(R) bit to 25 Nm (18 lb-ft), placing a 17 mm wrench on the nut attachment of the ball stud bracket while holding the bracket in place.
^ CAUTION:
To maintain the proper torque, the ball stud bracket bolt MUST be retightened after a minimum of thirty (30) minutes.
Wait a minimum of thirty (30) minutes, then retighten the bolt to 25 Nm (18 lb-ft).
b. If the distance measured is less than 43 mm or greater than 52 mm, go to Ball Stud Bracket Relocation.
3. Close the liftgate window.
4. Cycle the window to check for proper operation.
BALL STUD BRACKET RELOCATION
1. Support the center lower edge of the glass with a suitable safety stand.
2. Pry up the spring clips and disconnect the right and left support struts from the ball stud brackets located on the glass.
3. Place a 17 mm wrench on the nut attachment of the ball stud bracket to hold the bracket in place and loosen (clockwise) the attachment bolt two (2) turns with a T-30 Torx(R) bit.
CAUTION
The specified Threadlock and Sealer MUST be used. Do not allow the Thread lock and Sealer to come in contact with the vehicle body.
4. Apply Ford Thread lock and Sealer EOAZ-19554-M (or Loctite(R) 242) to the threads of the bracket nut attachment. See Figure 2.
NOTE:
Rotating the ball stud bracket back into position may take up to 40 Nm (30 lb-ft) to release the bond.
5. Place a straightedge against the inner edge of the ball stud bracket. Using a 17 mm wrench on the nut, rotate the ball stud bracket to a position where the distance between the edge of the glass and the straightedge is 48 mm at the lower corner of the bracket. Hand-tighten (counterclockwise) the bracket bolt. See Figure 3.
6. Tighten (counterclockwise) the bolt to 25 Nm (18 lb-ft) while holding the ball stud bracket in place. Check the 48 mm measurement after the initial torque.
CAUTION
To maintain the proper torque, the ball stud bracket bolt MUST be retightened after a minimum of thirty (30) minutes and a maximum of 60 minutes.
7. Wait a minimum of thirty (30) minutes, then retighten the bolt to 25 Nm (18 lb-ft).
8. Clean the glass surface where the ball stud bracket was previously bonded to the glass.
9. After both brackets have been retightened, connect the right and left glass support struts to the ball stud brackets.
10. Close the liftgate window.
11. Cycle the window to check for proper operation five (5) times.
