rear end probs

[chris1212]

I hear a sound coming from my rear like i have a flat spot on my tire when starting off in each gear. After reaching speed it levels off and turns to a roaring sound.It has fluid. must be some type of bearing.only thing i've done to the car is install new issis rucas from enjuku and a full line up. My tire prob from this point on is fixed but now i have this issue. I also noticed i have play in my axles at the pumpkin. Im going turbo and woould like to fix this. I no i need to upgrade. So what do you guys think i should do thats not balls to the wall. Just wanna reach 500hp some day and the rear end to handle the abuse...1996 240sx se

Check the other stuff first like your diff and subframe bushings and make sure all the bolts are nice and tight for the DS and axles... it coul also be a carrier bearing on the DS

Ok i just jacked her up and the first thing i noticed was th first bushing where the first two drive shafts meet..is dry rotten and broken. So this could be my problem.
