Lower Hinge, Front

Start the replacement of the door-side front door hinge after breaking down all necessary components and removing old sealant before marking the hinge pillar with its former position. Appearing vinyl glue around each weld mark before using 100 grit sandpaper or finer to softly scratch the door hinge surface. Drill holes through the hinge base with a 13 mm (1/2 in) rotabroach hole saw at each marked punch location while keeping away from drilling into the door material. Clean away all remaining welds from the hinge area before putting on the new hinge by using a chisel. The backing plate mounting surfaces must receive cleaning before preparation for mounting. At the same time, repair any damage to the door which occurred during removal. Position the service hinge at the scribe marks and punch the central area of each hole location. Drill both a 3 mm (1/8 in) pilot hole and an 11.5 mm (29/64 in) hole at each pilot point while verifying the drill bit size accuracy. All exposed metal surfaces need a primer application according to GM 4901M-D-2000 which specifies permitted re-finishing substances together with prohibited paint pairing systems. Use full-bodied caulk on the hinge mounting area before aligning the hinge with door holes to install the bolts tightly at 25 N.m (18 lb ft). The last steps involve applying sealers to finished surfaces while refinishes become necessary. The reinstallation of all components occurs after the process.

Commence front door hinge replacement by first clearing all associated parts followed by removing excess sealer from the present hinge location and writing down the position on the hinge pillar. Scrape away the 100 grit or finer surface of the existing hinge to identify its four door weld locations while marking the weld centers for drilling later. Use a center punch to mark the centers of the four weld marks on the original hinge base while avoiding drill penetration of the door. Drive a 13 mm (1/2 in) rotabroach hole saw through the hinge base to match the punch points. Thoroughly remove the hinge by using a chisel as needed while clearing away all remaining weld material so the service hinge can fit without gaps to the door surface. After fixing any door harm caused by drilling or hinge removal you should clean and prepare both backing plate mounting surfaces with a flat profile fit. Set the service hinge inside the door scribe marks then use center punches to mark each hole position according to the hinge. Drill three center punch holes with a 3mm (1/8 inch) pilot drill starting from the exact drill bit size before moving to the 11.5mm (29/64 inch) hole at these pilot markings. All exposed metal parts need preparation followed by approved anti-corrosion primer coating before applying full-bodied caulk to create a secure boundary across entire hinge mounting surfaces. Use the hinge along with the backing plate to match up with the door holes before tightening bolts to 25 N.m (18 lb ft) tension. The last procedure includes applying the sealers before finishing the metal surfaces according to specifications while reattaching and aligning all functional components.

You should start by taking off every object connected to the front side door hinge and then cut away all unnecessary sealant from around the current hinge before marking its position on the hinge pillar. The existing hinge needs soft sanding using 100-grit or finer sandpaper on the places holding the four door welds so that you can easily drill out the middle points of the welds for removal. Carefully strike center punches at each of the 4 weld locations on the base hinge before drilling to prevent penetrating the door. Use a 13 mm (1/2 in) rotabroach hole saw or equivalent to drill through each punch location on the hinge base before removing the hinge by separating it from the door using a chisel. Remove all remaining weld material from the door surface so the service hinge will have a level fit. The damaged areas from drilling and hinge removal should be repaired before cleaning all surfaces of the mounting areas on the backing plate for proper fit alignment. Place the service hinge inside the scribe marks and mark the hole locations on the door with center punches. Drill a 3 mm (1/8 in) pilot hole at each center punch point while using a drill that matches the exact measures before moving on to drill an 11.5 mm (29/64 in) hole from the pilot marks. All bare metal surfaces must be cleaned before preparing the refinishing process where GM 4901M-D-2000 GM Approved Refinish Materials is consulted to determine suitable products for selection while maintaining separation between paint systems according to paint manufacturer instructions. The entire mounting surface of the hinge demands approved anti-corrosion primer followed by full-bodied caulk to achieve complete sealing. The hinge alignment with door holes must occur before installing the bolts which need a torque of 25 N.m (18 lb ft). After the installation of sealers proceed with the metal surface refinishing process then place all affected panels and components back into position.

Begin the front side door hinge body side replacement by first removing every adjacent component before cutting off unnecessary sealer and marking the hinge pillar where the hinge will be mounted. You should apply 100 grit or finer sandpaper along with your hand to sand the existing hinge until you find all four weld points that connect it to the pillar while punching the middle of each weld for easier drilling. First, mark the center of each weld on the original hinge but do not drill into the hinge pillar. Afterward, use a 13 mm (1/2 in) rotabroach hole saw or equivalent to drill holes only through the hinge base into the punch marks. The service hinge requires complete removal while you use a chisel to uncover the pillar surface until it lies evenly with the service hinge. The pillar should receive repairs after drilling and hinge removal before placing the service hinge inside the scribe marks while simultaneously punching centers at each stud position on the pillar. Set the drill at exact size to make a 3 mm (1/8 in) pilot hole at center punch locations before creating an 11.5 mm (29/64 in) hole for the studs at their pilot points. All exposed metal surfaces need cleaning as well as preparation for anti-corrosion primer application before inserting fish wire (GM P/N 15017229) into the hinge and through the conduit hole of the pillar. Install stud (GM P/N 15017230) into the wire end and pull it into position with the hinge while the fish wire remains in the wire end. Install one more pillar stud a single time by feeding the providednuts (GM P/N 11516746) through the pillar after fitting the stud at its designated locations. Fully apply full-bodied caulk over the complete hinge mounting surfaces before securing each service nut. Use the supplied nuts to mount the hinge onto the pillar before torquing the nuts to 25N.m (18 lb ft). The technician will clean all required surfaces for refinishing work before applying sealants and subsequently repairing or repainting these surfaces as needed before aligning and installing all relative parts.

Begin by removing all related panels and components.

Use a chisel if necessary to separate it from the door.

Feed fish wire through the hinge, the hinge stud hole, and out of the conduit hole in the pillar, then install the stud into the wire end and pull it into position.

Position the service hinge within the scribe marks and center punch each stud location on the hinge pillar.

Refinish the metal surfaces as necessary, then align and install all related panels and components.

Apply the sealers, refinish the metal surfaces as necessary, and reinstall and align all related panels and components.

Begin by removing all related panels and components.

Draw the stud tight through the pillar using the supplied nuts and repeat for the remaining stud locations.

A 13 mm (1/2 in) rotabroach hole saw.

Position the service hinge within the scribe marks and center punch each stud location on the hinge pillar.

Lightly hand-sand the hinge with 100 grit or finer sandpaper to locate the four welds.

Drill a 3 mm (1/8 in) pilot hole at each center punch location, followed by drilling an 11.5 mm (29/64 in) hole at the pilot locations.

Apply a full-bodied caulk to the entire hinge mounting surface for a proper seal, then install the hinge to the pillar using the supplied nuts, tightening them to 25 N.m (18 lb ft).

Repair any damage to the door and clean and prepare the backing plate mounting surfaces for a flush fit.

Lightly hand-sand the existing hinge with 100 grit or finer sandpaper to locate the four welds attaching the hinge to the door, and punch the center of each weld.
