My 4wd has quit on me just in time for some deep snow and I think I have narrowed it down to my t case clutch pack being burnt up or possibly a broken chain. The 4wd system operates like normal but I don't get any power to the front driveshaft from the t case. I am wondering if anybody knows of or has any good info. on rebuilding a 236 autotrac transfer case from an 01' blazer (diagrams, parts suppliers, etc.) I have had a lot of trouble finding such info. on these types of transfer cases. Thanks!

 

You have the NV236 transfer case. Your best bet for rebuild instructions is likely going to be a Factory Service Manual. AllDataDIY.com has some decent instructions and does list some OE part numbers, but the FSM will have better info.

As far as I can tell with some quick searching through my usual sources, the dealer may be you only option for parts.
