SJ Manual Hubs

There isn't a lot to go wrong with a manual hub. Do you have a working one on the other side?, if so swap them over and see if the fault moves.

Fault moves = faulty hub

Fault stays = possbile broken CV joint??

They can stick if not greased inside and have got rusty. You can take them apart and grease them, I did mine when I got them some time ago and have sealed them up with Hylomar Blue sealant everytime I have taken them off the car which keeps water out.

It could be that the spring is trying to push it onto the splines but isn't quite getting there so is rubbing against the edge of them causing the clicking noise.

I can never remember if you install them locked or not, I think it's unlocked and I've not had too many problems with them like that.

I've taken to undoing the bolts that bolt it onto the hub with a spanner and not undoing the ones on the outer part at all, which I used to do to be able to get a socket on the inner ones.

That's probably an admission of idiocy as it's probably what everyone else has always done!

I think the general advice is to install them in the "free" position. I think the manual mechanism places pressure on the spring to force the inner locking ring forward when in the locked position. It is then possible when fitting them "locked" to jam the locking ring if it is not smoothly fitted on the splines.

Fitting them in the "free" position allows the locking ring to float and find its own resting position more easily.

And, no, you cannot do up the inner bolts with the top cap fitted on some models of locking hub. Put the hub to "free" and remove the cap.
