Rebuilding a transfer case is not an easy task for a do-it-yourselfer; for it involves dismantling of many small parts and rebuilding them again and the measurements of clearance are exact and need adjustment through the help of select-fit spacers and snap-rings. While it is possible to change the transfer case or install a new one, the overhaul is better left to a transaxle repair shop for reasons of time and cost; a rebuilt transfer case may be obtainable via a manufacturer's dealer parts department as well as from auto part stores. It should be noted that even though the above teardown was carried out by an experienced mechanic and highlighted nuances that an inexperienced mechanic might miss, an inexperienced mechanic can also successfully rebuild a transfer case if he has the needed special tools and approach the procedure methodically. Required tools that may be needed include internal and external snap-ring pliers, bearing puller, a slide hammer, set of pin punches, dial indicator, possibly a hydraulic press and a large heavy duty workbench. It is equally important during disassembly and dismantling process, one should record and document the connection and the manner that the components are fitted. It can be easier to understand and diagnose the properties of the faulty zone in the transfer case and to trace the potential troubles by checking the codes twisted to the transfer case system.
