I'm tired myself! Heading home to swap out another brake booster (I'm getting good at it!) and then probably going to try and set the pinion angle and cross my fingers the brakes work and driveline vibration goes away then. If it works, the jeep is finally drivable again! Gotta pick a friend up who was originally coming in at 7:40 but now cause of delays it's bumped back to like 10:30. Ugh!
