I was told at the weekend that some people do use a thrust bearing and a lock nut.
Now this confused me as a thrust race is used to isolate the diff screw from the relative movement of the two diff halfs ..... on the BJ4WE the outdrives are keyed together so the relative movement is not really there. I think a big improvement would be a shouldered head on the bolt (to increase the frictional area) and a locking washer ...... that may well help stop it coming undone.
