    Weather finally warmed up enough for me to install the 3rd member from east coast. I'm following monkeyproof's excellent write up, but I'm having a problem getting the elocker gear to shift over all the way to the right. The picture shows its position. So when I rotate the axles via the drive shaft connection they both rotate in the same direction. I've tried rotating the drive shaft connection as I try to move the elocker gear further to the right but no luck... any suggestions appreciated... thanks and Merry Christmas

    This looks as far over as it will go. I’d suggest spinning a tire in both directions and try to get the differential to unlock.

    Thanks I'll get my wife out there and give it a try... just an FYI I looked at the old third member and pushed the gear over until the shifting fork hit the edge of the casting and couldn't go any further. Then rotated the pinion connection and the internal axle connections both turned in the same direction...go figure???

    Now really confused... I did as suggested and I can get the two brake drums to turn in opposite directions at the same time, but when I turn the pinion connection both drums turn in the same direction. I obviously don't understand what's happening inside the third member, so any suggestions or education would be appreciated.... thanks

    If you turn the driveshaft and hold one of the wheels only one will spin. See my video here with the rear diff unlocked both rear wheels spin same direction.

    Yeah!!! I got everything put back together and everything works as it should, what a relief. Not sure why I could never get the wheels to rotate in opposite directions while turning the drive shaft flange, so just a note to others that this may occur. Also sharing a photo of the tension strap I used to secure the drive shaft as it made it super easy to uninstall and reinstall without having to hold it or worry about it falling. Thanks to all that offered their help and for previous postings.

    Now it's time to replace the carpet and the 2 front seats ... I'm sure I'll have some questions.... thanks

    Assuming that both wheels are level and floating in the air.

    Rotating one wheel, just rotates the axles around on the spider gears. They rotate opposite each other due to the 3 "gears" the 2 axles and the spider gears create. No ring and pinion involvement.

    Rotating the drive shaft would include the ring and pinion. With both wheels floating they have the same traction and both move forward with the ring. Spider gears don't move.

    Couple real basic but good videos.
