Half shaft question--spacing visible

[Apex02]

Just was going over my truck that I got last week and noticed the left rear half shaft seems to have some spacing at the wheel. Figure this is not good. Anyone know what the fix for this is?

Ooof, yeah, not good. I'm guessing the retaining bolt has backed off. Need to pull the hubs apart and replace the nordic washer and inspect/service all of them.

my guess is the same.
that's the bolt i am thinking of.
if this is the 1, it wont be much labor to get back in place.
loctite it.
torque it to 37 ft.lb

Also check that the lockwasher is on the bolt. If the bolt was too short or the half shaft came out far enough to drop the lock washer off, then it would be floating around in the geared hub.
