Squiky take off? Newer car
 

Hey guys, I just bought an 08 GT 1 week and 3 days ago. I love the car its amazing. All of a sudden its doing some weird squeeks. Heres the story. On the past weekend, I painted the calipers on the car friday. I did them on the car, taped them and painted them. The wheel lugs were way over tight my impact gun wouldnt take them off, I got them off with a big socket wrench. (not sure if this matters) This was 6 days after i got my car. Saturday came and the car was still driving fine, We had a HUGE storm saturday and it was the first time it seen rain. Saturday night I went out for a cruise and it was fine then to. On sunday it started. I thought it was something i had in my trunk, so I took it out and it wasnt. I thought maybe it was cause of the rain, but its been 3 days now. Its a strange noise. It happens everytime i take off from a stop. When i go over bumps I dont hear it. It seems when their is a weight shift from front to back I hear it. But driving down the road you dont hear anything. The sound is similar to a door closing slowly that needs it hinge oiled. If you guys have any idea what might cause this Id love to know

Thanks
Kevin

The bushings in the rear suspension might need lubed.

See if it does it at turning at low speeds.
If so check out the tsb for it.

Google Mustang Noise while turning at low speed TSB.

Their are several things this could be. I would start with the sway bar end links. Spray them with some white lithium grease and see if it goes away. I would not lube everything in the rear suspension just go piece by so you can determine what the sound is. Also check the rubber exhaust hangers, you mentioned you had some exhaust work done. Process of elimination..

No exaust work was done. Ill greese it piece by piece and get back to yoy guys. It does squeek at a slow roll but always when I'm stopped and let off gas
