    Are there any real concerns with changing the rear yoke besides torque' on the pinion nut? Is there anything else that I have to do?

    After mine continually loosening up and destroying the seal, I locktited the nut, and siliconed the surfaces that *might* leak...the washer to yoke surface mainly.

    The pinion nut torque is fairly critical, but my experience has been that if you tighten the yoke as much as possible with a decent sized ratchet, on an already setup ring/pinion, you'll be fine.

    Like I said, mine came loose multiple times (3) and each time I tightened it up, with no audible problems. Usually the gears will howl, etc., if the ring/pinion aren't meshing correctly, so I figure it's "close enough". I've now been driving on it over a year, and no problems.

    I'd not go with too big a bar, as you could conceivably crush the sleeve in there. That takes a lot of force, and with the axle in the vehicle, you'd have to work to get something large/long enough to crush it further in there. (or perhaps use an impact wrench)
