  Q: How to replace the upper and lower liftgate hinge on Chevrolet Suburban 1500?

  A: First analyze factory specifications for damage then begin removing all related parts from the upper cargo hinge area. Mark the hinge angle on the pillar during removal then take out all unused sealant. Use a 13 mm drill bit to make holes in the necessary factory welds at the hinge access panel, pull out the access door to get better access, and drill through the hinge welds from the center. Remove the hinge from its pillar with a chisel when necessary. Prepare and clean the pillar surface while installing the service hinge according to specific requirements when applying anti-corrosion primer and full-bodied caulk to the mounting area. Place the service hinge directly on the scribe lines and attach its hardware. Tighten bolts to 25 N.m of torque (20 lb.Ft.) before refitting all parts. Examine and fix the lower cargo hinge while removing its associated parts and getting rid of any excess sealer as part of your inspection. Use 8 mm spot weld remover tools to drill out factory weld markings at the lower filler of the rear body opening while also center punching four weld locations on the hinge. Handle the filler panel with great care since you need to restore its exact position. Use a 13 mm (1/2 inch) rotabroach hole saw at each punch spot to make the drilling. When needed, a small chisel removes the hinge from the pillar. Clean the pillar so the service hinge sits evenly and fix any damage while positioning the hinge exactly on scribe marks. Use a center punch to mark bolt areas then begin by drilling 3 mm (1/8 in) pilots which you will follow with 13 mm (1/2 in) holes at the pilot marks. Apply approved paint to all raw metal areas and use complete sealant before placing the hinge into position where it lines up with the pillar holes. Tighten the bolts to 25 N.m (20 lb.Ft) when the fasteners are installed. Weld the lower filler material in its original factory spots after first making necessary metal repairs.
