Hello!

I have this clunk in the rear end when I let off of the the gas pedal in gear (coasting/decelerating) at ~1500 rpm. It's much more pronounced in the lower gears (1 and 2) and can happen when engaging 1st or reverse. The car has had this ever since I've received it about 3 years ago and now it's time to get it fixed! Apparently, it's a drive shaft issue and I think the clutch fly wheel can be replaced too (nearing 90k). I've having a shop take care of the drive shaft... Should I just go ahead and have them also replace the clutch while they are there? Will this save me some labor or should I wait it out a bit longer? Sometimes I hear hear it "rattling" at idle - they tell me this is the flywheel.

Thanks all!
