rear end feels loose

[amplifi3d]

For the past 3 days the rear of my car feels loose or wobbly. Everytime I hit a small blemish in the road it feels as if my driver rear tire is kicking out and making the rear shift out to the left. Occasionally, when driving at about 20-30 mph i can hear the tires squeaking, similar to how welded diffs squeak when driving in a parking garage but just not as loud. Nothing to huge but it makes me feel nervous driving the car. I think i've also noticed some tire dust on the inner side of my body kit in the rear.

So today, I put the car on the lift today and i checked if the subframe bolts were loose, the sway bars, the perches on coilovers, and pretty much all the adjustible arms. Everything seemed normal. I had gotten an alignment a week prior but I'm 90% sure the car didnt drive like this when i got it back.

I forgot to check the lug nuts but i specifically remember torquing them down the last time i put the wheels on.

Anyone has similar symptoms before with their cars? Could it be a wheel bearing? I heard when they go bad they start to make noise but i've yet to hear anything.

I do alot of drifting the car aswell.

Thanks for everyones time!
