DeLorean Door Adjustment
Arguably the most recognizable feature of the DeLorean is its super glammy gullwing doors. Of the handful of manufacturers who have produced gullwing doors, the DeLorean's (aside from the new Mercedes SLS) are generally accepted as the most reliable.
First, a cryogenically set torsion bar designed & manufactured by Grumman Aerospace "untwists" and begins to lift the door. As its limited power runs out a standard strut takes over and lifts the door the rest of the way in an uninterrupted & sexy manner.
At the factory the early cars, such as mine, had door alignment problems. Sometimes the doors would not close properly, or only one latch would catch as there were no door guides. My car has the early stainless steel quality control guides and I've always had to slam my doors. In the winter the rear latches catching were dependent on temperature. The colder it was, the less chance they'd have of catching. I decided to fix them.
I carried my toolbox into my garage and opened the driver's door to reveal the bolt. The black paint on the bolt and washer were quite worn. It was clear that my door had been adjusted before.
Using a 17mm wrench I loosened the nut around the latch bolt about 3/4's of a turn. This allowed me to move it around within a small area. It is attached to a larger plate on the other side. I wasn't sure if that rear plate would fall off, but the design wouldn't make sense if it did. So I chanced it... and the plate stayed put.
I moved the door pin around then slowly closed my door over and over, carefully watching the latch as it swallowed up the bolt. After about 10 minutes of fiddling, I had the bolt in the perfect position and tightened it up.
Had I known it was this simple, I would've done it years ago.
I shut the door repeatedly, very happy with the results. I no longer have to slam my driver's door, and the door panel is aligned perfectly with the body! Unfortunately, I could not seem to figure out the passenger door, so maybe it's not that simple after all.
