Rear of car popping like hell

[MustangLife]

Something on the rear of my car is popping like crazy when turning. It started about a week ago once a day. Now today it pops around every turn, sharp or any kinda turning. When going fast or when going slow. The popping is louder if I'm going slower. Right I have stock axles and differential which have never been raced on. I have x2c upper and lower control which have not been raced on since March. Also when going slow it feels like its kicking the car out to the side.

What do you guys think.

Wow, 32 views and no replies. I'm came to the conclusion that its the differential. The spider gears are about to break. So the cars parked now. I guess I'll 31 spline it again since its gonna have to come out. I had a 31 spline in it for about a year and then decided i was gonna sell it or trade it in and than decided not to. So I guess its back to building the car again.

Josh, have you tried putting in a limited slip friction modifier? The stuff that Ford sells is supposed to be one of the best.
