Rear noise problem

[AUIIForte]

Hay hay!

Recently I've had problems with my stock sound system, but things are all sorted out now and everything is working fine because of the help of a few very nice and helpful people here who where willing to help me out!

Well, now I have another problem.

As I was driving down a road in wet conditions (my rear tyre tread was low on both wheels) I came up to a roundabout with a very sharp curve through the whole turn if you wanted to go straight (which I did), as soon as I was half way through the roundabout there was a P plater in a VN drifting around the turn coming up behind me from the right. He lost control and started to slide right towards me uncontrollably and pretty fast, so the only thing I could do to avoid any accident was to speed up. I did speed up and in the end I did avoid him crashing into me, but as I sped up, my tyres lost traction after about 5 meters of driving and the back of my car slid out to the left onto the dirt that was right next to the road. There was a gutter and my BACK LEFT TYRE hit that and bounced up onto the side of the road...

So thats ok, nobody is hurt and the guy in the VN was pretty damn apologetic, he also went off the road and bounced over the small gutter onto the side of the road.

Blah blah, cut to what my problem is... Now as I drive, when I'm going above about 30km/h I hear a squeak on the back left side of my car, and as I speed up and travel at higher speeds, the squeak speeds up like "squeak.squeak.squeak.squeak" from "squeak...........squeak.............squeak".

My original thought was that there must be something wrong with the suspensions or shocks because if I applied the brakes and the weight of momentum was transfered to the front of the car (back of car rising slightly), the squeaking would stop, and as soon as I let go of the breaks, the squeak would come back!.

I took the left rear wheel off to inspect everything, but nothing seems out of place. As i'm not very good with identifying things that a wrong because I am inexperienced I was hoping for some advice to what to look for? If you like, I can take photos with the tyre off or on just to maybe help?

Thank you!
