Putting together a 12 bolt. Put in a new Ratech #3111 crush collar and got up to 300 ft/lbs on the pinion nut and couldn't get more than 10 in/lbs of preload. Was afraid to go any further for fear of stripping pinion nut. Took out that crush and got new one from Strange. Compared the 2 with a mike and the Raytech was .020" longer. Put in the Strange and got the recomended 18 in/lbs preload at 160 ft/lbs on the pinion. Anybody run into this?
