How do you permanently lock a ball bearing differential?

if you don't care about damage to the balls, race or other parts then crank it down as hard as you can. Though you would have a better experience just getting a "spool" diff or solid diff.

Any way to permanently lock a ball diff is going to ruin something. Is there a reason cranking it all the way down won't work for you?

I have had a look through your threads. All of these JB weld silly puddy methods are for gear diffs. You have a ball diff which has the huge benefit of being adjustable. All you have to do is is crank down the nut (PN 110097) all the way. If that isn't tight enough remove the diff spring and replace it with washers of the appropriate size ... and crank down the nut.
