Clutch Rattle when lifting off throtle at 60 mph?

[91Bomb]

Just had my clutch changed, Exedy stock replacement w/oem TOB + Redline fluid, and now when I lift off the throttle going 60-70 mph in 5th gear there's a noticable rattling/grinding type noise. It's not super loud but annoying nonetheless and didn't do it before clutch + fluid change. Any thoughts?

Check your axles. It may just be a coincidence that it started after your clutch replacement. I almost had an axle fall apart as I was driving and it would make a lot of noise when you let off the gas. It was most noticeable at highway speeds.

Is it more of a 'resonance' than a vibration? Do you have an aluminum flywheel??

Car is bone stock 1g FWD turbo with exedy stock replacement clutch. Maybe the difference is the synthetic gear oil because I'm assuming it was not synthetic before but don't know. It's not a real bad rattling but it's a noticeable noise that wasn't there before clutch change so not sure what to think. Clutch has over 500 mi on it now and it doesn't slip or anything and pulls hard which it should with engine compression 160-160-160-152 on orig motor at 162,000 mi
