Unhappy Star Washer Issue

I have a Dana 70 rear end that's using the 2 wheel bearing nuts and a star washer in-between them.
I tighten and nut and provide the backlash, put the washer on, bend the tabs, and go to torque the outer locknut.
My problem is when I torque down the outer nut, the inner tab of the washer that's in the axle keyway shears off rendering the washer useless.
What am I doing wrong? I've trashed 2 new washers already.
Thanks from a first time poster and new member of the forum.


them.

I have only seen that happen when the outer is over torqued.

So I guess that begs the question, what torque should it be tightened to? I've been seeing 150 Foot Pounds.

so you are bending the tabs over the inner nut before torqueing the outer locknut? I thought the tabs get bent over the outer lock nut after it is torqued?

I was bending the tabs over the inside nut. Am I doing it incorrectly?

Where did you get 150ft/lbs from?

Dana 60/70 full floater wheel bearing adjusting nut - 50 -80 ft lbs, back off 1/4 - 3/8 turn. (Check for play). Lock washer - bend a tab or two over the adjusting nut, or use the same bent ones in the same place.

Wheel bearing locknut - 90 - 110 ft lbs
Axle shaft retaining bolts - 40 - 50 ft lbs

Thank you. So the tabs are bent over the inside nut and the outside nut is torqued to 90 - 110 ft lbs. Got it.
I'll keep you all posted of my success.

Yes a couple of tabs get bent in (on a flat nut side) to lock the inner nut, and then I bet you might be able to bend one out to catch the outer nut (flat side) also. Yes it has been quite a while since I was in there.
