Weird noise after 4 speed install

@rklein383 Drivelines NW rules. I have had a dude with a jeep come to me and say the driveline was fuckerred and the shop couldnt do anything but build hima new one. I took it to DLNW and dude said gimme two hours. BAM. Not all shops are created equal. If its not the diff or trans.....get a second opinion on that driveline. ie have a different shop balance it or at least spin it for you.
