Tailgate Removal - GMC 2008 Sierra 1500 Pickup Owner's Manual

Tailgate Removal

The tailgate can be removed to allow for different
loading situations. Although the tailgate can be removed
without assistance, you may want someone to assist
you with the removal to avoid possible damage to
the vehicle.
To remove the tailgate, do the following:
2-14
1. Raise the tailgate
slightly and release
both retaining
cable clips. To release
the retaining cable
clips, lift the cable so it
points straight out.
Lift the clip over
the bolt, and push the
cable forward then
rotate down.
2. With the tailgate about halfway open, lift the right
edge of the tailgate from the lower pivot.
On vehicles with the tailgate assist feature, raise
the tailgate nearly all the way to the closed position
prior to removing the left edge.
3. Move the tailgate to the right to release the
left edge.
Reverse this procedure to reinstall the tailgate. Make
sure the tailgate is secure.
