just back from checking the rear end , i didn`t remover the cover put removed the drive shaft and rotated the pinion, the backlash felt good but the pinion had a hard feel to it not like when i installed it, smooth even turning, so i back of the nut and re-torque it to 75lbs ( down from 90lbs) it felt smoother turning and on a test run the noise was noticeable lessened. i know the the crush sleeve should be replaced but how close do you have to be to the drag#`s on the pinion, is it better to be under the 20-25inlbs? i set it at 24inlbs which was at 90ftlbs when i started.
