kazuhiko Member 39 Member For: 11y 5m 30d Posted 07/06/14 03:48 AM Share Posted 07/06/14 03:48 AM Hey Guys,Got a Fg Sedan manual. Recently noticed a knocking coming from under the car, wondering if you guys have an idea of what it is.So the story goes, it only happens when taking off in first, only happens below 2krpm, I can feel it like is under the centre console ( I always have my arm resting on it). It doesnt happen in any other gear and doesnt happen in any other rev range sofar. its 5-6 real quick thuds and its only just started happening in the last few days.Any ideas of what im looking at?

kazuhiko Member 39 Member For: 11y 5m 30d Posted 07/06/14 02:29 PM Author Share Posted 07/06/14 02:29 PM (edited) So some further info on the car.I bought it standard, no mods at all. I put on a xr8 intake pretty quickly.Within the first month of thinking it was my old RX7, I burned out what was already a worn clutch. So I threw in a Malwood clutch with further mods in mind.The car has 78000km on the clock. Now the reason I think it is the drive shaft is because my brothers R31 back in the day had some sort of a driveshaft issue because it had a hard life on the streets and track. His sounded similar to this, but a lot more violent and was under any kind of load.As I said, as far as I can tell, with various street testing, it only happens in first gear below 20kmhr giving it throttle. It sounds like its coming from directly under the centre console. I can also clearly feel it.In the spirit of things, I have recorded it and its attached below. Its doing my head in and im not going to drive the car anymore incase it makes whatever the problem may be, whether it is actually bad or notm until I get it checked out. Being the long weekend, its doing my head in MORE!Have a listen, turn the speakers up!
