That's my plan. I'm hoping for a u-joint fatality.

If you don't find any problem at the clamshell, then you can remove the right brake drum and left side axle tube bolts, and pull the axle assembly out the left side.

I agree with Tom but I think it's almost best to undo the clamshell and pull the rear axle back a little . you can then use a pair of channel lock pliers to tey and turn the driveshaft, you can complete removing the rear axle further back to access the left side housing easier to remove and also check out the u-joint and driveshaft. It's possible you have a pinion bearing issue , u torque tube/houaings and hopefully not a gear issue. Your spiders and axles appear to be ok as you turned them both in opposing directions ok .
Let us know. Best of luck!!

We had the very same thing happen in my shop last summer. One of the driveshaft bearings had disintegrated, and the small rollers were locking up the ring gear. I'll bet that is what you will find when the rear is disassembled. Car was driving down the roadway, and suddenly just locked up.

My efforts will now have to wait until Saturday. Delayed by good weather!

I had a problem with the same symptom in a '30 CCPU I once owned. The bearing in the torque tube (near the U joint) came apart and the rollers jammed between the drive shaft and the inside of the torque tube.
Transmission would shift, but letting the clutch out would stall the engine. The rear wheels were locked up.
Remove the rear end and check torque tube before cracking open the differential.

UPDATE! Returned today to lower/roll out rear end assembly. We found catastrophic failure of universal joint. Easy fix, back on the road this afternoon. Check out the photos.
Thanks for all of the responses!

You sure did luck out.

Is this what happens when you don't pack the cavity full of Mystik JT-6 High Temp grease?
