My wife is experiencing a 'clunk' while driving or shifting and I have been unable to locate where this comes from. I followed all the troubleshooting details in the repair book for front/rear CVs, both driveshafts, center dif bearing, universals, etc. Couldn't find a thing wrong. At first, it started to 'clunk' only when shifting the car; both when clutch is pushed in or released. Now it also does this when you accelerate/decelerate. Also, is it only a coincidence that since she first told me about this, it started right after I replaced both front calipers (old ones were binding badly) and completely bled the system? However, I didn't bleed the clutch (don't ask me why )--Would this be a reason? Any idea what else to try?

You didn't say what you did to the propellor shafts. Assuming you only inspected them, try greasing all the fittings. It may be a dry spline that needs grease.

Another possibility is a bad clutch plate. There are springs to take up the jolt of clutch engagement. If they are weak, then they can't do their job and the clutch engagement and release will be too sudden and may sound like you describe.

To be exact, this model has no grease fittings on the universals. And according to my book, when they're bad even if there is the slightest movement in the shafts when you try to move them. Also, I'm not too suprised that there doesn't appear to be any plugs I can remove to install grease fittings either. I guess that's typical 'throw-it away-and replace-when-it's-bad' manufacturing.
However, you're incite concerning the clutch springs is well taken and unfortunately, that's similar to what my nephew inferred when we discussed it. Normally I would do most of the auto repairs myself on our cars but after reading the manual, it doesn't sound like something I'm able to tackle. Oh well, I guess it's time to break out the checkbook and see a mechanic!
Thanks for your help--much appreciated.
