Safely shifting a nut on a differential bevel pinion

[dennis52]

Thanks for the helpful advice.
I shifted it this morning ,not without some trepidation. You turn the socket wrench about 90 degrees and only get driveline flexing,then you finally hit firm resistance and wham the nut gives way all of a sudden.
Quite different than other nuts I have removed.
I am sure somone wiser will explain what was happening.

probably taking up all the backlash in the driveline before it gets tight.

that's why an impact sometimes makes it easier... for instance. not an easy job to take a crankshaft nut off a crank snout without spinning the engine, if you used a wrench.. ont he other hand.. and impact driver spins it right off...

Trying to torque it back up to the specified setting , I just could not get the torque wrench to click, so I tightened it back to align with a paint line I had previously made on the diff case
