So after i replaced my diff, i find some more problems.

had the car jacked up, fixing the brakes and then notice with the car started, in neutral the rear wheels where spinning then stopped after a bit...

is that normal !!!@!@#! ????

second, is i have an ACT clutch, with oem disc(i think) and with the clutch in its silent, all is well. However with the car in neutral, or decelerating there is a chatter, a sound like the disc is vibrating or the pressure plate is vibrating, not sure.

 

Even in neutral there is enough oil/mechanical drag in the gearbox to spin the rear wheels a bit when they are off the ground.
Especially when the gearbox/oil is cold.

 

ahh, kk, what about the clutch noise, now that you have said that and what i've researched it might be the act kit itself.... but it's really bad... well enough that my wife is like 'wtf is that noise now'

 

bump, clutch rattle loose sounding, yet drives fine, bolts tourqed correctly, qtf tree

 

Do you have an aftermarket flywheel? My ACT clutch/flywheel combo chatters when it's in neutral most of the time. Not terribly bad, but noticeable.

 

FWIW: my Comptech FW, OEM disk and ACT PP buzz like a fridge at decell in any rpm above 3500-4000 in any gear.
I guess its the combination.

 

its soooo horrid... kills it
