I bought a 1983 245 a month ago in California, and I drove it back to Minnesota. Somewhere in Iowa, when leaving a gas station, I heard this loud scraping, grinding noise, from the rear of the car?it sounded to me at first like a brake was binding. No brake smell, though, and as soon as I accelerated past 30mph, the noise was gone.
It didn't come back until I left Chicago, some 800 miles later, also at a low speed. Then it dissipated and I drove the 400 miles to Minneapolis without incident.
I'm posting here because I've seen a handful of threads describing this same problem, none of which have been solved. The noise would occur every time I drove the car (i.e., every time it warmed up), for a few minutes, and then would go away if I kept driving.
The noise definitely tracks rotation of the wheels, and happens whether or not I am in gear. At low speeds, it almost sounded like my dad's Karmann Ghia did when it needed a new axle shaft IIRC (periodic clunk/scrape with each wheel rotation).
It seemed to be getting worse (heard it when going 65 one day), but then it went away completely. I heard it once for about 10 seconds a week later. I decided that it must have been the handbrake pads having worn out entirely, so elected to have them replaced. The handbrake was worn and at its full adjustment, but it wasn't the source of the grinding.
So now, I have a new handbrake, and no grinding to diagnose, but I'm paranoid that there may be an issue with the differential, or something else.
Most notably, it's finally gotten tolerably warm here in MN?and others reporting this issue had claimed it went away for months at a time when it was warm outside. What could that imply?
Thanks in advance for any suggestions. I know it's kind of impossible to truly diagnose, but I had to ask just to see if anyone had solved this obscure problem.
