Loud squeak during half-clutch.

[2.7boxer6]

Hey Guys,

When I am pull off the line and give the car an excessive amount of gas (1500ish rpm) while the clutch is still in halfway (bad practice I know) I get a loud squeak from the rear.

It also happens if I am changing up coming off the clutch slowly and give it too much throttle with the clutch not all the way out.

I know applying too much gas mid clutch is not good but is there an underlying issue that would cause the squeak?

Thanks a lot, guys.
