Read the re-build guide on GNTTYPE.ORG...........you don't need precision balancing equipment if you re-use the stock wheels and there is no housing damage. Of course the should be no scoring on the shafts either. If you take it apart to have a look and even if you do have to get it sent out, most vendors don't mind a "pile of parts" as long as it's all their and packaged well. If there's just a little bit of shaft play, bearings and seals will be fine.......done it lots and no problems....ever. Type "Garrett rebuild" in the E-Bay search engine, buy the T03-T04 kit and have fun. If you buy the kit and chicken out after taking the turbo apart, re-list the kit on E-Bay and take pleasure in the fact that you at least tried. Good luck. (Honestly it's not hard!)
