All depends if it's the inner or out ball joint.

i've replaced the outer on both sides before with no ill after effects.
if it's got t*ts or wheels it's bound to be trouble...............prove me wrong.

Outer can be replaced with a press and can be much cheaper than replacing the whole arm. You will need a press though.

There is a special tool available to help replace these balljoints.Tool cost about £100,though.

Here in the UK,a pair of decent quality arms and rear bushes will cost about the same amount,so if you are likely to need to swap the balljoints on more than one car,it may well be worth investing in the tool.
