Hi all - I've been noticing this rattle in the transmission/drive-axle area that sounds like nails in an aluminum can under acceleration. I typically hear this sound under WOT or just cruising at lets say 35mph in 5th/6th gear. I'm looking to get my the G tuned, but want to figure out what sound this is before taking it to Church Auto. Can anyone recognize what may be making this sound or is it normal of G35 transmissions?


FYI, I'm on a stock clutch, flywheel and throw-out bearing.

Thanks in advance!

yah panging..What grade gas are you using?

 

Using 91 premium Shell or 76. Also running on 10W30 Mobile1 full synthetic with 125k miles.

 

i think VQ engines ping time to time.. I've been having that sounds since new..

uphill, hot day, A/C on.. accelerating.. almost guaranteed to ping a bit.

 

You can try seafoaming the engine.

 

I guess I don't see how it could be an engine-related sound? I only hear it when i'm driving at low RPMs, in gear. If I'm in neutral and rev, I don't hear the clacking noise.

 

Yeah, if it was ping, it would happen under moderate to hard acceleration. There is something else going on there.

 

Texas did u listen? I only hear him hitting the lanes markers, pinging, and switching gears. JT can u identify the times in the video u hear the bad noise?

 

Its very faint in this video, but its 0:11-0:12, 0:14-0:16, 0:28

 

Right when ur lugging on the gas.. it's just pinging/pre detonation

 

I even went back and played it on a good set of speakers, NO, I don't hear it. I hear a slight rattle, but no pinging. When I put **** gas in mine once, it was LOUD.

 

I'll have to record it again tonight to get a better sample.

 

Aren't g's known for having the rear axles make noise? My g makes the same noise and I'm pretty sure that's what it is.

 

I have this same issue, not sure what it is, if you find out please post back

 

Well just go ahead and take it tochurch auto, they can telll you.
