Okay, heres my problem. I did the fourthgen rear swap, and now the thing makes this godawfull dry scraping sound. It sounds like its comming from the discs. I checked them and everything is in there right and there is no rubbing. The axels seem like they have alot of play in them. Is this normal for a rear end? I swaped from drums so I couldnt pull on the axels like I can on the disc rear. I put in the new prop valve and everything,so I do not think it is a brake issue, becasue the noise continues when I aply the brakes. I checked the gears before I put it in no chipped teeth or metal flakes in the fluid. What i think is happeningis the axles are moving out ward when I start to drive casueing the rotors to rub the pads. Someone please help.

 

The axles normally have some end play, usually anywhere from 1/16" to 1/8".

Look at the inside of your wheels very carefully. I'd bet they're dragging on some part of the brakes.
