It really easy too rebuild turbos, you can buy a rebuild kit online for like 40.00 and take the wheels and shaft to disel injection to get balanced for 35.00.

Their is only 2 C clips that hold the bearings and shaft inside the turbo. Only tools you need is a 13mm, a 11mm i think and a small hammer....

If that dont work get a BIG hammer and smash that POS!
