Trunk Lid, Tailgate
Rear window and tailgate, alignment
- Alignment procedures involve adjusting tailgate, window, and
spoiler to have equal space between
iefl and right sides and
to be flush with body. Measurement locations and specific di-
mensions are shown.

gate to body. Then adjust fit of rear window to tailgate.
Clearance of the rear window is adjusted by adding or re-
moving shims between hinge bracket and rear window
(maximum of three shims).
Adjust spoiler gap to body last.
Height of spoiler is set by alignment of the rear tailgate.
Gap of spoiler to body is set by adjusting spoiler attach-
ment fasteners.
- Lateral and vertical alignment of the window and tailgate is
done using hinge bolts. Fine adjustment of the tailgate to the
body is made using rubber stop buffers and latch assembly.
Spoiler gap specification Rear spoiler to roof 4.25
