So my driveshaft departed my truck yesterday on the way to work. Along the way it took out the transfer case and the adapter to the transmission. I never could find the old driveshaft so I need to know what length to look for. Truck is stock with the NP246 transfer case and is stock height with no plans of lifting but theres a tiny chance it will get slightly lowered.

Can someone measure their stock RCSB 4wd driveshaft for me or point in the direction of a reasonable priced alternative? All the local yards want 250-350 for a used shaft with old u joints in them.

 

I just had mine shortened for the 4l80e swap, and they painted it otherwise I could get the part number off of it. That would be your best bet imo, just see if anyone has the part number for rcsb 4x4 driveshaft.

 

That's a good idea that I hadn't thought of.

Would a driveshaft from a standard Yukon be the same length or are they the same size as an extended cab truck?

 

I'm not sure on that one. Might be a different length than both.
