Suburban 3/4 Ton 4WD V8-305 5.0L (1986)
Figure No. 6 - Glass and Sash Channel Guide
-
Check the angle of the sash channel guides to ensure they follow the curvature of the glass and sash channel (see Figure No. 6). If adjustment is
required, carefully bend the guides to the same curvature as the glass and sash channel. Ensure that the guides travel through the channel smoothly.
Figure No. 7 - Tailgate Window

Tailgate Glass - Check curvature of the tailgate window. Lay straight edge on glass and observe the clearance between straight edge and glass at
center of window (see Figure No. 7). If clearance exceeds 1/4 of an inch replace the glass.
7.
Ground Strap - Install a ground strap (12 gauge wire) from the tailgate to the frame. Attachment can be made from one of the tailgate hinge
bolts to one of the holes in the rear frame crossmember. Use a star washer with each bolt to provide good metal to metal contact. Make sure the
ground strap does not become kinked when the tailgate is closed. Ensure that the motor is grounded properly to the tailgate. This can be
accomplished by replacing one of the window regulator motor bolts with a zinc chromate coated bolt, P/N 9419004.
8.
Tailgate Fit To Body - Check flushness and height of tailgate to the rear quarter panels. If the top of the tailgate is misaligned (in or out), loosen
the strikers on the inside of the rear quarter panels and adjust accordingly. If alignment (in or out) is off on the bottom of the tailgate, loosen
hinges and adjust as required.
