I'll say. Picked up a dial indicator and mag stand on ebay for $20, which was instrumental. Plus I needed a beam-type in/lbs torque wrench to test the pinion preload, my clicker type wouldn't work for that, to me that was the most anxious part. The R&P instructions called for 25 in/lbs of preload (rotation resistance) on the pinion which honestly felt tight (OEM looks to be 10-14 from what I read) but it confirmed in a few other areas for these modern replacement bearings. Hope that's right, or I'll be back in there at some point for another go-around.lots of detail and patience huh!
