Think I finally broke something. 4x4 let go last night doing boosted launches. No problems until I the last run, went to launch and realized 4x4 wasn't engaged. Never any noise or pop, just no power transfer. Jacked it up today, actuator is working fine, low range engages just never locks the front driveshaft. I'm leaning towards the front output being broke but I don't feel any play. All guesses right now, ill know this week hopefully!

On the bright side, 13psi launches like a dream with the lowered stance. Very smooth out of the hole. Probably did 7-8 launches

Not yet. I will try to do that this afternoon to troubleshoot a little further before it gets torn down

I manually actuated it, something definitely let go. No grinding of any sort, just no power to the front driveshaft.

I may have an output shaft ill have to check not sure if you want a used or not

I may have it taken care of but if not, how much you want for that used one?
