Its hard to disassemble a ball bearing turbo and put it back without fucking it up. On top of all that, its hard to get the balance back once its disassembled, hence the reason theres no rebuild kits for ballbearing turbos. You usually need to get it rebalanced during assembly. Get a rebuild kit, its only like $80-110 depending on where you get it. I just rebuilt a T04S using parts from Gpopshop.
