soo... after launching the car today, I'm wondering if the dealer is right (possibility of T.C. going bad)... I drove the car a little hard and now there is an occassional crackling noise. The best I can describe it would be stepping on a drive leaf. When this happens, the car loses power; meaning, it slows down a bit (bogs).

It doesnt even happen often, but it scares me.. I checked to see if anything was rubbing on the tires, i drove it around a bit and boosted it (runs great, pulls hard as normal), pulled the wheels off and checked Axles for play, checked steering rack, looked at out side of T.C. for the heck of it, searched the turbo for shaft play... NOTHING.

Is it possible that the ring & Pinion in the TC is doing this?...Maybe the rear end?
It only happens on occassion. Odd. I'm not entirely sure the T.C. is goign bad though. I've read so many threads where ppl complain about whining at partial throttle only (my case) and in fact it's more of a lite wissle than a whine, and loudest at partial throttle..

Is this my T.C. failing you think??? I've put appx 3k miles on the car since I was warned.

 

easy fix. Just turn the music up and the problem will fix itself. Works everytime for me.

 

rofl.....too bad my system just got stolen

 

LOL! for the noise, YES. For the power loss, NO.. I dont car about Noise... lol. Power is what im conserned ith. Radio is always there, power isn't when things like this happen.

 

 

Seriously though, I've heard that could be the sound of a TC going bad

 

Bump for some other opinions and help please..

 

"standing on a leaf" or " crumpling up aluminium foil" (like the stuff you use in a kitchen for wrapping sandwiches, food for the fridge etc.

associated with loss of power - if the above is happening in conjuction with each other then I would say that sound like DETONATION!!!

DET sounds exactly like "standing on a leaf" or " crumpling up aluminium foil" sound coming from the engine bay.

that is it will only be det if you are under power and hear that sound - if not happening together then its something else.

what fuel / boost you running? might have a bad tank of fuel

93 Octane/19psi, TBE, intake, BOV.... thats all i have, and it loses power maybe at low boost, or even vac... havent gotten close enough look.

 

UPDATE!!!! - Noise seems to be happening only on left-hand sharp turns.

 

You busted your front diff. Common when you launch the car. Sorry

 

That's what I was afraid of.. I had a feeling it might be diff related.
Anyways, It happened to make the crackling noise at a stop light tonight. I slowwly pulled off the light and it crackled for a sec. Still think it is diff related or does this change things???

Also, What would you reccommend doing?

 

My buddys STi had the same problem... ended up being engine mount... hope that helps...

 

I would still have the same diagnosis. I was split until you said it crackles under left hand turns, that is a stereotypical destroyed front diff.

I would recommend replacing it, and try to launch less.
