    '79 8 lug D44.

    This has shims instead of a crush sleeve to determine pinion bearing preload, correct?

    What should I torque the pinion nut then too...just crank down on it?

    Reason I ask is this:
    There was some gear oil coming out of my pinion, but not really leaking past the seal. I took out the driveshaft, locked the hubs, put a wrench on the pinion nut, and gave it a turn. Without much effort, I was able to tighten the pinion nut (maybe 30-40 ft. lbs) The nut was obviously loose. So, I tightened it down with some locktite (didn't get out the torque wrench...but tightened it probably close to 140 ft. lbs) It's now a little "harder" to turn than before.

    Any ideas/info?

    Pull the cover and check the ring and pinion for unusual wear. You may have damaged your gears without enough preload.

    Correct, jsut tighten it down. The shims set the preload. If it came loose, and you drove on them for a while, the gearset could be no good now, but if it wasnt too long it might be ok. Just tighten the nut back up til you cant anymore.
