Car: 1989 SC 5 speed, 150k miles, bone stock
About two months ago, my car started making a noise under acceleration in any gear. There would be a thump-thump-thump coming from under the car, from the transmission or driveshaft area. The thumping would increase in speed in relation to the car's speed, not the engine RPM. It would get louder under WOT or 3/4 throttle, but go away when coasting in gear, clutch in or out.
The past couple of days, the thump-thump-thumping has increased to a very loud metallic clanking sound. Again, it's loud when accelerating in gear, and it goes away completely when coasting in gear, clutch in or out, or in neutral. It's very loud and can be heard from outside the car as it drives by.
Any ideas? I was thinking maybe a U-joint on its way out? How can I check that? What else might be causing it? I have to go to work in a little bit, but when I get home I might be able to get the car up on ramps and inspect underneath it
Thanks for any help
