First forgive me, my jeep isn't a true Rubicon, I have a 98 with the Rubicon axles in it. So now to my issue, I am currently regearing to 4.88's. I've set my pinion preload to 15in/lb, when I installed the seal and torqued the nut to 160 ft/lb the pinion is hard to turn and when I checked it it was at 50 in/lb. I'm at a loss. I'd run the t but am afraid of overheating the bearings. Any input is appreciated.
