The truck is up and running great. The rebuild on the T-case fixed the “squeaking” noise, I’m pretty sure the rear housing output bushing was the culprit but the other worn/replaced parts were needed. No more knock when shifting from reverse to drive.
The Borla xr1 sounds amazing. Very subtle and quiet but still has a nice sound to it. It feels like the added back pressure definitely spoils this big exhaust housing a bit faster. I’m in love with driving the truck all over again. Zero drone at any cruising speed. The electric cutout for an open 4” is ridiculously loud especially with the dump under the cab but it’s needed at times.
I also finally got got around to ditching the Calmax drop hangers that I got with the Caltracs bars and installed Belltech 2”drop hangers to level the rear to the front. The Caltracs brackets fit perfectly inside the Belltech hangers. However I did have to notch the Belltech hangers to allow space for the lower rear rod end nut on the bars.
Wouldnt surpise me if it was, mines seem some abuse, and i fought a rear seal leak and finally replaced the bushing after buying a tool to do it in the truck which helped that but think it just needs gone thru like you did.
like the exhaust setup, would love to do something like that on my other truck..!

Thanks, I love the exhaust tone now. I just need time away from work and kids with someone to film some video of the exhaust besides just idling.
I believe the main shaft spline wear is due to 1. made out of a softer, weaker metal than the rest of the hard parts and 2. high milage of stop/go and shifting from reverse/drive since the wear is on both sides of the splines. I've taken apart 3 of the np149's that were out of a stock 6.0 and all had the same wear at the tip of the main shaft. If you do go through your 149 and choose to pull the pump off, be prepared to replace the main shaft bearing and reluctor wheel. On 241's, 246's ect. they slide right on and off. the 149 needs to be pressed/pulled off which isn't easy since the pump is in the way and the lengthy output shaft.
