hey guys how are you

i have 2010 mustang gt auto stock and i ve noticed that there is a wierd noise coming from under the car, it happend when the rpm is between 1000 to 2000 when driving normally or kinda slowly from 40 to 60 km or 20 to 40 miles
when in second geard and third but when driving fast its alright the sound i like somethin loose or rattling like taaaaaaa than it goes away
could it be my exhaust ??

i dont know if this is related but when u go wot for few time and step on it some time i can feel some rattling althoug i dont hear it that much , i had a problem whith my exhaust tips not being even and they adjusted them and sound kinda went away. you guys think its related ot its just normal

 

Could be a loose exhaust hanger or other exhaust component under the car, I have a similar sound that mine makes and cant figure it out.

 

You might take a peek at TSB 06-4-1.
I know this TSB is for 05-06 Stangs, but it fixed my 07.
The exhaust hanger isolators on the trans cross member might be loose.
It's a cheap $4 fix. Ford shoulda fixed this one by now, but who knows......

 

TSB 06-4-1 what do you mean



whats that???

 

Can't seem to find that TSB. Link?

A TSB is a technical service bulletin basically a directory Ford putd out for problems they experience with our cars and the fix...

i went under the car and i didnt see anythin loose from the mufflers to the midpipe not that i can see

i checked that tsb page and for my car i didnt see anythin related beside the axle whine

 

Here it is. It's RPM related, so I thought i'd throw it out there. Might be worth a look.

The 05-10's (yes, your '10 is pretty much the same as the '05-09's) are notorious for rattles due to a few chronic issues and all deal with harmonics at certain engine RPM's:

1. Tranny separator plate (there's a TSB for this)
2. heat shield rattle
3. exhaust hanger-to-frame contact
4. exhaust clamp, retorque required

 

so should i be worried or is it just normal??


because i wana get a catback and some springs and that might effect the warranty so if its something that kinda serious and need to be fixed i dont wana **** with the warranty


what should i do

 

And where, by chance have you been so misinformed that a catback and springs might void your warranty? Tell the panty hose wearer that gave you that informatipon to turn in his man card and shut his f**king trap.

That kind of crap just burns me up.

You're under warranty now so take it in and at least it'll be documented.
