(the car's, not mine)
The right rear spring (I thought) on my '71 Mach decided to crap out last week - luckily, just after I got off the interstate. I was getting a "rub rub rub" sound from the RR. The car was sitting visibly lower on the right than the left. What the heck, I was planning on changing the springs anyway this winter, but I hadn't planned on getting the car towed home to do it (thanks, Hagerty!).
I changed the springs out (after an epic fight with a rusted front bolt), and the ride and height are exactly was I wanted. Unfortunately, as I was test-driving the car, the "rub rub rub" sound came back after a couple miles of no sounds. This time I drove slowly back home, and noticed a pattern where the noise was "rub rub rub" for a few seconds, then a sound as if a spring is tightening, then a POP, and the sounds all went away. After 10-15 seconds, they would start again. No change in handling or driveability.
This could be the brakes, but there's no indication of dragging or problems stopping. I'm thinking it may be the axle shaft bearing causing a problem (it was screwed up when I bought the car; I had to replace the axle shaft it was so badly worn by a spinning bearing on it).
Obviously I'm going to take the the axle apart. But I'm throwing this out there so maybe somebody has an idea or two what else might be the problem.
