I am facing this problem whenever I close my throttle abruptly at say above 3000rpm, I heard this loud noise coming from my engine area. It sounds like its coming from the gearbox. It sounds like "WARRRRRRRRRR" when you try to pronounce it loudly. What can it be? I'm on a Spoon LSD. Do all B18C5s with LSD sound like that when you release the throttle? I have a bad drive shaft seal at the moment which is leaking MTF very slowly. Could it be my gearbox is out of transmission fluid?

 

uhhmmm.. sounds like grinding metal
be careful and drop the tranmission
look for metal shavings
hope its nothing serious
good luck

 

I would definetly check LSD and Tranny fluid levels to see where they are. LSD making clunking sounds when turning is strange. CV shafts can make that noise only when they are siezing.

 

My guess is that your tranny fluid went low and one or more of your bearings are shot.
