And no, it was not me squashing the springs down. I only weigh 155 and am not "a big ol' boy".

The correct fix would be a new set of leaf springs. That is a little bigger project than I wanted right now, so I thought that adding a single helper spring to the left leaf spring might straighten the car. I bought a pair of Made in China “Superior Automotive Overleaf Helper Springs”, Part #11-1030, from Pep Boys at 20% off for $35.99 + $2.52 tax = $38.51.

“Increase level load carrying capacity by 1000 1bs. with one pair. Hardware included. For leaf springs 1.75” to 2.5” wide (mine are 2” wide). Weight: 11.15 lbs (5.6 lbs ea). Helps eliminate sagging springs due to additional weight capacity. Will provide approximately one-inch lift in rear when not loaded.”

I added one helper spring on my left leaf spring last night and it took about ten minutes to install:

I drove the car to work this morning and the new helper spring made the ride just a little bit more firm. I measured the height to the fenders when I got to work and found 19” on the left and 19 ¼” on the right. The car sits 1/4” higher on the right, but it is barely noticeable. While driving home today I did not even notice the new helper spring.

The operation was a success.
I love finding out about new info like this
