I am dealing with this problem and I still have it! I took my GT in for a squawking rear axle when I make slow right or left turns. You have to get the rear end warmed up by driving about 25 miles and then it starts squawking like HELL! the first time I took it in the mechanic rode with me and said he couldn't hear it, I wanted to smack him right in the mouth! they didn't want to do anything..untill i bitched like Hell and they reluctantly agreed to order the clutch packs for the rear end, It took more weeks of waiting and they fianaly installed them and the problem went away for about a week and then came back even worse!!!! I am now going back on monday
to have them look at it again! I am going to bitch and bitch untill itis fixed!
I bought a brand New car and it sounds like a rusty wagon wheel turning back there.
I am going to demand a complete new rear axle from rotor to rotor! then if that doesnt fix it, we are going to replace the entire transmission even if it has nothing to do with the problem, if they dont want to do their job, I will Shotgun it with The most expensive parts on the car....They will fix it or I will kick their asses.!
