Just put a 4th gen rear in my car and when I take a long kinda sharp turn (Slow) I get a bad Screeching sound from the Pass. side rear....I have put new rotars and pads on and have changed the rear diff fluid...Anybody have any ideas?

 

please....I have 2 boy's I take with me in the car and if it is something that could be bad I need to find out what it is and how to fix it.....
