I have the rear axle assembly out of my 53 Commander and I am trying to loosen the pinion shaft nut. There is only like 1/2 a thread of the shaft showing beyond the nut, so I can't tell what type of threads I am working with. Is is righty-tighty/left-loosey or backwards? Any other tricks to getting this nut off that has been in place for 58 years?

Facing the pinion shaft, clockwise - tightens, counterclockwise - loosens.. Hope this helps.

That does help! Now let's hope that with some combination of thread juice, heat, and torque I can get that nut loose!

Thanks.

Impact wrench works every time. Just hold the socket tight in the direction that you are rotating it to minimize shock load to the gear teeth.

Use a 1/2 in drive electric impact , lefty-loosey

Don't forget there are torque specs to follow when you put it back on, assumming you are replacing the yoke seal.

The 'proper' way to do this is to use a pinion yoke wrench to 'hold' the yoke (and pinion) while you remove the nut (and re-torque upon assembly).
Here are several pic's of such tools.

Easy enough to hold the yoke with a homemade tool.
Impact wrenches work well to remove, but can brinell the pinion bearing rollers into the races, and impart a pretty good shock load onto the gear tooth face.

Incidents of collateral damage are low, but possible.
Your service manual has all of the info listed to do this job properly.

No argument with all the above tools but I use a large Crescent or pipe wrench on the yoke while I utilize the torque wrench. Remember the specs call for 180+ ft-lbs of torque on the pinion nut. Impact wrench for disassembly.
