To install an oversize bushing kit, you will need to remove the door from the vehicle and disassemble the hinge. Once the hinge is disassembled, you can remove the old bushings and press in the new oversize bushings. Be sure to use a press that is capable of applying the proper amount of force to seat the bushings properly.
Once the new bushings are installed, you can reassemble the hinge and reinstall the door. Make sure to align the door properly before tightening the bolts.
Oversize bushing kits for 2003 S-10 door hinges are available from various auto parts stores and online retailers.
