How do you change door pins and bushings on a 1999 Chevy blazer?

Answer 1

REMOVAL & INSTALLATION

See Figures 1 and 2 Fig. 1: A spring compressor tool must be used to remove the springs when working on the doors/hinges

Fig. 2: Exploded view of the door hinge pins

The following procedure requires the use of a door hinge spring compressor such as J-36604-A or equivalent. # If equipped with power door components, perform the following procedures: ## Disconnect the negative battery cable. ## Check for access to the wiring by removing the cowl side vent cover. If access is possible, remove the receptacles from the wiring harness, then remove the retainer from the wiring harness grommet. Remove the rubber conduit from the door pillar by pushing it from the vent cover side. ## If access is not possible, remove the door trim panel, then unplug the electrical harness connector from the power door lock motor and/or the power window regulator. Remove the harness from the door. # If available, apply cloth-backed tape to the door and body pillar for protection. CAUTION

Before removing the hinge spring from the door, cover the spring with a towel to prevent the spring from flying and possibly causing personal injury.

# Using a door hinge spring compressor such as No. J-36604-A or equivalent, compress the door hinge spring and remove it. # To remove the door hinge pin clips, spread the clips and move them above the recess on the pin; when the pin is removed, the clip will ride on the pin and fall free of it. ## Using a soft-head hammer and a pair of locking pliers, remove the lower pin from the door hinge; then, temporarily install a bolt (in the lower pin hole) to hold the door in place until the upper hinge pin is removed. ## Remove the upper door hinge pin and support the door, then remove the bolt from the lower hinge pin hole and remove the door from the vehicle. To install:

# To install the door, position it on the hinges and insert a bolt through the lower hinge pin hole. # Using a new hinge pin clip, install the upper hinge pin. # Remove the bolt from the lower hinge pin hole. Using a new hinge pin, install it into the lower hinge pin holes. # Compress the door hinge spring and install it into the door hinge using the door hinge spring compressor tool. # If equipped with power door components, re-engage the wiring and install the trim panel or pieces, then connect the negative battery cable. ADJUSTMENTS

Factory installed hinges are welded in place, so no adjustment of the system is necessary or recommended. Service replacement hinges are bolted in position and may be adjusted. If your vehicle is equipped with service replacement hinges, please refer to the door hinge adjustment procedure located later in this section. Depending on the type of door hinge you have, you wont have the clips mentioned above. If this is the case there will be a silver cap that sit on the top of the door pin. all you have to do it hit the top of the pin with a BF hammer (or rubber hammer) and a punch. The pin will come straight out. One thing to be aware of, as soon as that pin is out it will put all the pressure on the other pin. U should use a bucket and place it under the door so that it doesnt fall too much. I did mine yesterday and it took about 30 minutes. If you have the right tool (which I didnt) and someone to help you it should be no longer than 30 minutes. Good Luck!!!!!!
