Trailer axle seals short life

[t700]

Thanks Hammerhead for your reply.
We have the Stemco Pro-Torq bearing nuts.
The nut we have is the 447-4743 which is the only one with the 1/4 final back off.

On the next seal will try 1/8 final back off, check end play with gauge, and monitor
temperature on the road.
