8. Using one of the preferred methods below measure and record the gap between the liftgate flange and liftgate glass at twelve (12) different locations as shown. (Figure 1)
a. Modeling Clay
(1) Use any type of soft modeling clay and insert softened balls of clay in twelve (12) locations. (Figure 1).
(2) After the clay is firmly in place, close the liftgate glass until it latches. Making sure not to slam glass, causing the clay to not read the correct height dimensions.
(3) Raise glass, and measure the depressions left in clay and record. (Figure 1)
(4) Remove clay pieces one at a time, use a marker and make a dot on sheet metal of each location where you measured.
b. Alternate method when modeling clay is not available.
(1) Close the liftgate glass and open the liftgate.
(2) Use a metal ruler or equivalent to measure and record the gap between the liftgate flange and liftgate glass in twelve (12) locations as shown. Use a marker to indicate where each measurement was made. (Figure 1)
9. The specification for glass to sheet metal flange gap is 14 mm +/- 3 mm (9/16" +/- 1/8"). Using the recorded measurements, adjust the sheet metal flange with a pair of duck bill pliers or flange pliers until the flange is within specification.
