Once we got to a good sledding hill I decided to spin some donuts in 4 low to clear some snow. Bad ideal...... 4 low in 30-36” of snow spinning donuts and pop goes the front drive shaft. Thankfully I keep a spare in the truck. I was able to swap it in 15 minutes.
The problem is the np263hd transfer case uses a 1310 u joint. It’s not capable of running anything bigger because of how close the front output is to the electric shift module on the housing.
After talking with Trevor at WFO Concepts I decided a hybrid NP273 transfer case would be the best option. It will allow me to run a 1350 u joint up front and is a much more stout transfer case.
I called Transfer Case Express, they convert them to bolt up to the Allison and add the GM speed sensor in the tail housing. A week later I had it ?
I used a clocking ring to index the t case down and clear the abs module, even though I still had to massage the mounting bracket for clearance. This t case is way bigger than a 263xhd and I also had to extend the wiring harness about 8” for the speed sensor plug.
