Trunk Lid Hinge Problem

Hi Guys: Have kind of a strange issue with the hinges on the trunk lid of my 62SS. The lid opens fine but the torsion rods only want to hold it about half way open. That could be either the position of the torque rods or they're simply "tired". However, here's the bigger problem, when I go to close the lid from that half way position, its first met with a little resistance then it seems like I have to overcome a "bump" or notch in the hinge before it will continue to close. This causes a slight "clunk" sound and mild resistance, then it will close fine. The question is this...could the hinge itself or the hinge pin be worn so as to create an oval hole that it has to jump into and out of that causes that "clunk"? This leads to the next question, is there any trick to removing the torque rods? I think I will take the lid off, release the rods, and take the hinges out and have a look. Just wondering if anyone has run into something similar before. Thanks!!

I'm familiar with that problem on some of my parts cars, and really don't what is causing it, but believe you have it covered in your procedure to check it.

To take out the Tension Rods, find the correct size pipe needed and use it for leverage on the ends. You may need a large screw driver to help bump it over for it to release. And use caution.

Torsion rods are springs, and springs sag with age. The extra notches here made for different trim level trunk lids that had more or less weight depending upon the number of tail lights or trim attached to the trunk lid. You may be able to try for a different hole to increase lift.

The torsion rods that hold the trunk lid open can be adjusted as others have said. The settings range from the least tension (both 'rods' the bottom rungs) to the most tension (both rods on the top rung). Three intermediate settings are available because the rods may be moved 'up' only on one side. Find the tension setting that works best.

As for your 'clunk', have you tried getting into the trunk (it's big enough) with a light, and watch and listen to what's happening as some one closes it? If you don't trust anyone enough, you may remove the lock/latch
