Yes.but it might jam up against the axle but it will come out.
Beware that the bolts might be rusted to the bush sleeves and then you've got a right pita on your hands.
You mean the large nut?
Try leaving that alone and just drop the axle end? It'll hang down quite a lot iirc and give you the Access you need to work on the rigger.
It's one of those jobs that often snowballs into a pita as I said.
Get a spare nut and bush for the rear end and get some heat on it.If you want to remove it completely then get new bushes bolts nuts for the front too. If you don't need them now you will in the future
