Default Again: rear end is leaking and making clunking noises

well to make a long story short. I've been to the dealership 3 times over the past 2 years for my rear-end making clunking noises and the seal leaking. They have supposedly fixed this problem each time but still I am having the same problem I had over a year ago. This is a weekend driver only and I never go to the track. I realize that this is a common problem in these cars but shouldn't a dealership know what the hell there doing.

Basically what the car is doing is when I turn one direction and then turn another direction at very low speeds there is a noise like something is moving around in the rear end. It sort of sounds like play in the rear-end. Also when for example I'm turning into a parking spot faster than normal there is whistle noise like something is rubbing. I have already checked the exhaust and that is not the problem.

The car is still under extended warranty so what should I do? Someone please help as I'm about ready to just go ballistic on the dealership.

Thanks in advance

Are they putting the posi additive back in?
I would request a new posi carrier and double the additive, it may be the clutches/cones popping. This is common in GM rears and they know this! And the seal shouldn't leak if installed properly.

Yes they are putting the additive back in. I'm new to this sort of stuff. So I will request that whenever I go back to the dealership

C-clip axles have some in/out play. But it shouldn't be a big clunk.
You might also have slop in the Panhard mounts, these need to
be kept really tight. Might as well just lube & tighten all your
suspension links to spec before more involved possibilities.

Weep from the nose may be pinion side-play, from poor setup or
the crush collar getting beat down or from a driveline angle /
imbalance / runout problem kicking the seal off seat constantly.
The pinion play should have specs that can be verified.

im sorry its not really a clunking noise its more like a dragging type noise. Its feels like something is rubbing and not fitting together properly. After the dealership fixed it it was okay for awhile and now its doing the exact same thing. The thing that irritates me is that I never even drive the car but maybe 80 miles per month.
