Help help!! Z32 noise underneath!!! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So long story short 92 TT car 5speed. Put a different set of injectors in along with a new z1 ecu chip and took car out for drive..... Well, it did great through the gears no grinds as usual came to a stop and dropped clutch around 3500-4000 rpms to see how the chip and injectors would react. Awesomeness happened spun 275s like they were nothing started to wheel hop through second so I feathered it back and grabbed third everything seemed fine until I came to another stop...

Rolled up to the red light like every other time but when light turned green and started to roll it started to sound like hmm my first guess was interior piece was loose and plastic was making that rubbing noise it does. Then it kept doing it until I came to a complete stop. I rolled down the window and found out noise was coming from underneath car.

As I go faster the noise kinda disappears, when slowing down the noise gets a little louder and the "chirping" noise gets slower. My first thought was tranny but ruled up to light in neutral and makes same noise. The slower the car rolls the longer and slower the noise sounds so is this coming from driveshaft 2piece shaft?

Makes worse noise when moving slow disappears when up to speed and kinda feels like it vibrates now but barely enough to think about it???

Let me know what you think.

Busted carrier bearing?

not really... when you get under there, take hold of the driveshaft, move it around, and watch for any excessive play in the carrier bearing. If so, I would suggest investing in a one-piece driveshaft.

Have you tried leaving it on neutral with the e-brake and reving?

If its still making the noise it cant be the carrier bearing since it doesn't spin on neutral, just my 2 cents.

If that is the case and you're not experiencing any problems in shifting, it's more than likely your pilot bearing or clutch release bearing is out.

He said he feels it vibrates. Last time I had a pilot bearing problem, car didn't vibrate. If you rule out the vibration I agree, it can be the pilot/throw out bearing

The same thing happened to me. But my starter fell off and I dragged it about 10 miles home.
