Technical Front Sus Ball joints. Could I change them myself?

[DubWitStilo]

Hi my front suspension ball joints are worn and I was thinking about replacing them myself. I was quoted a price of €300 from my local Fiat garage to get this done, But i was hoping to save some cash and do it myself.

I have recently changed my front and rear Brake pads with relative ease so I'm wondering would changing the ball joints be just as easy, or should i leave it to the professionals?????

Ball joints could mean track rod end or lower ams so which are we talking about..?
