help with rattle please and other general questions
New to me 07 GT. I have a few questions. I have a rattle that almost sounds like a baby rattle maybe a mettalic sound to it coming from what I think is the rear passenger side. Thought it might be the brakes. I replaced pads and rotors and it's still there. It goes away 2 mins after running car. I heard it at idle not moving in park. While moving straight and while turning. Although it seems to happen more when turning. Very intermittent. Generally happens after car sits a few hours. I do not think it is exhaust hangers.
Second while doing the break job (1st one for me) I notice I can rotate the wheel I hear backlash noise from what I expect to be the driveshaft or tranny (auto). Is that normal?
Third. I noticed there is some play as far as moving the wheel in and out relative to the axle. Not a wobble but straight in and out. Both axles seemed to be the same. I am guessing thats normal but wanted some input.

I also have the same noise your experiencing, mine too from the back passenger side. Ordered new pads before I even looked to see if they we're worn, threw the car up on a lift and the brakes still have 80% or so left on them. At this point we figured contamination so we cleaned the pads off, re installed and the noise is still there. Mine comes on when i first start to apply the brake, as I apply more pressure the noise cuts off completely. Very frustrating.

I hear ya. I got the back wheels up started the car and let them spin in forward, reverse and turned them myself in neutral. Gave it some gas etc. I could not reproduce it. I got the diff fluid changed had the guys check again for loose stuff that might cause the noise. No avail. I removed the rearmost exhaust hangers on both sides just to see if it made any difference. None. The noise is hard to describe. Maybe baby rattle is wrong. It comes off as a tinny rasp sometimes. Very brief then just goes away. If somehow I discover the source I'll post. There are so many bearings, bushings etc. Just may have to get used to it until the problem that is causing this results in a failure. I read about this things called a mechanics ear. It is a fancy 4 channel listening device. I was thinking of putting an external mic on my cellphone and putting it in various spots under the car to see if I can zero in on where the noise is coming from.

There is a lot of slop or play in the driveshaft with it's 2 piece design. Noise when switching directions is pretty normal.
There is normally some end play in the axles. If it seems excessive I would check out the C-clips.

Crossing my fingers. I think it was the exhaust tip. Drove it twice. Last night and this morning completely cold. No noise after I took off the exhaust tip. Thanks again. Now on to the passenger seat.
