The answer is to find my manual but, if you saw my garage, you'd know why I'm going down the 'ask a question' route  :shock: 
My new (second hand) freewheeling hubs have arrived.  I understand that I can just fit them straight onto the SJ, but there is a bit that looks a bit scary to me!!  On the end of the axle is a gold coloured bracket held on with two bolts, in the middle of which is a screw that appears to hold a protective cover on the end of the shaft.
If I undo this, what's going to happen?  Am I going to have bits of axle fly off in every direction?  Or is it just protecting things?  I am hoping I can just unbolt it, remove the protective cap and slide the hubs on.  
Each hub also has a circlip with it.  Does this go on the end of the shaft?
Sorry to sound really dumb  :oops: I'm trying to 'do it muself' but don't want to make my poor SJ poorly and have to be trailered off to the garage due to randomly unbolting bits and bobs!!!!   :?  :shock:  :?  :shock:
