The Stemco procedure calls for torque to 200 spin repeat 2 more times
Back off
Torque to 100 spin repeat 2 more times
Final step back off 1/4 turn

Not sure what the final torque is

Will try your method with the final torque at 50

Thanks

Whoa whoa whoa whoa!!!!!
Are you talking the Stemco Pro-Torq bearing nuts?

IF YOU ARE, YOU MAY NOT BE FOLLOWING THE DIRECTIONS PROPERLY!!!
Please read Step 4 B in This instruction sheet again VERY CAREFULLY!
There is ONLY ONE TRAILER AXLE NUT THAT GETS BACKED OFF 1/4 TURN!!!
ALL THE REST ONLY GET BACKED OFF 1/8 TURN!

I’m thinking you’re axle nuts are too loose.
Verify the endplay with a dial indicator, this is the PROPER way to confirm you’ve done it correctly.
These bearing nuts are so repeatable it’s ridiculous. Following the instructions properly results in 0.001-0.002” every damn time. And I STILL verify it with a dial indicator.
I’m not kidding, I get well over 200,000miles running between 20-23,000lbs per axle!
No Problem.
I change seals after 3 years or so to change the hub oil, and I rarely have one fail in between time.
IIRC, I’ve changed 2 unscheduled trailer wheel seals in the last 10 yrs, and I have 6 trailer axles.
