Annoying Rattle Under Car

[Silver99]

A while back the car had a distinct rattle coming from under the car near the front.
Only happens during 2-3k And only when it is upon light acceleration but if i step on it no noise :shrug: Can hear when switching gears can kinda feel it in the clutch pedal
Does not do the noise while in idle
There is no power loss at all
Everything runs perfect
Any ideas?

Here are two videos so you can check it out
This one here is just going through the gears 1-4 i havent heard it in 5th


And this one is just while in neutral with me reving the engine up, the camera is pointed to Transmission under the car



Btw: No cats, Checked heat shield, no loose bolts, exhuast

so the noise is coming from the front...like engine bay?? or front of tranny?? sorry just trying to narrow it down..

[streetoutlaw331]

[streetoutlaw331]

[streetoutlaw331]

[Silver99]

yeah the year is a 99 gt 5 spd
and it sounds as if its comming from the tranny or around that area

Are you using an o/r x? Could be turbulence at the collectors. An offroad x will magnify this. If you think that's what it is, then you don't have anything to worry about. All offroad x pipes make a little rattle around 2500rpm. Mine does it between 22-2300rpm under medium throttle.

Every o/r x I've ever had made a "can-like" rattle just over 2k rpm, but just for a couple 100 rpm then it smoothest back out. Others have reported this too, it's been explained to me as turbulence where the manifolds meet the x.

Did this sound start after you put x pipe on?

That 2nd vid sounds like something got traped behind your dust plate on the front of your tranny.

Well when i first put the xpipe on there was no rattle

After watching the second vid, you've got something else going on. That's not exhaust.

Try to get it on a lift at like an exhaust shop and be under it to look around while somebody throws some revs.

Time and money are a issue for me right now but i will


You got any videos of the rattle on your car?

[Silver99]

Found this on another forum gonna do this as soon as i get home..
Hopefully it can be this and not anything more serious


Loose Flywheel or Broken Flexplate:
A loose flywheel or broken flexplate can usually be detected by this procedure:
1) Advance engine idle to 2000 rpm.
2) Turn off the ignition switch.
3) When the engine has almost stopped, turn the switch on again.
4) Repeat this procedure several times.
5) If the flywheel is loose or the flexplate is broken, a distinct knock will be heard every time the ignition switch is turned back on.

Here is a vid of when i just got under the car and took that little cover off the tranny to get a peek inside..
Someone was throwing revs at around 2k and im sure now its coming from inside here..

Have you felt any difference in the clutch? Shatter or vibration when engaging?

When changing gears and i am disengaging the clutch i can feel a rattle..
Ive played with the clutch one day and while i was switching gears i would move the clutch pedal in and out while reving the engine up and the rattle would be pretty loud

Might have be something to do with the pressure plate but not quite sure, only way to know for sure would be to remove the tranny IMO

i dont have sound hooked up to here noise,but wanted to pass on about a rattle noise i had with my cobra...on mine the bracket that holds up the abs junction was missing a nut and the bracket was rattling and sounded like the exhaust was rubbing and some times felt like clutch noises...the cover over the clutch fork also rattles
