Review on Dorman 742-251 Power Window Motor for Specific Models, Jet Black by George Saunier

Fitted left and right on a 1991 Bronco, this description should apply to at least an 88-91. DO NOT USE FAKE FOR THE REAR DOOR MOTOR. This setup is difficult enough under ideal conditions, treat yourself to an OEM or a remanufactured OEM. As mentioned in other comments, the mounting holes are misaligned. DO NOT alter the door openings as you will most likely screw up the gear alignment. The top and bottom holes are perfectly aligned, and the foremost hole is offset. If you use this motor, just leave the foremost hole empty. I reused the original screws as the screws provided look significantly larger. First set the window to its fully raised position and tape it to the top of the door, inside out, using several long pieces of tape to hold the window in place. . Removing three 5/16" screws for the front hole requires an open-end wrench and a screwdriver or socket for the other two. Reach your hand through the square hole above the motor or remove the speaker and use the hole. Hold the motor before removing the third screw. After removing all the screws, you may need to pry something with a screwdriver if it's stuck on the door. Then pull out the motor through the hole where the cables pass. Choose the correct Dorman cable (I connected both ends), at least connect the motor end, then plug the new motor into the hole. Align and run the top hole. Screw (while holding the motor with your hand through the square hole above the motor or through the speaker hole) make sure the bottom hole aligns. You'll probably have to push the motor (quickly press the window button) to get the gears to align. When you are sure the gears are aligned, tighten the two screws. Once fully tightened, remove the band and lower the motor so you can see the rail. Now is a good time to clean the rail with a wire brush, rag, 409, ANYTHING if you have lube, smear it onto the rail. . As a last resort, spray the rail with PB Blaster or WD40, although the grease will last longer. While you're there, spray all the other moving parts with WD-40 or a blaster, then close the door again. I don't have a part number but you can order a set of plastic fasteners to replace broken 30 year old door panel fasteners. Now is the right time for it.
