How to change the lower controls arms
 

I have an 01 volvo S80 that needs bushing and ball joints, so i figured its easier to change the whole arm and also not much more expensive. Is this an easy task? I have got as far as a brake job and rear sway bar links before on this car. How would ti compare to that. I'd also like to know if there are any step by step instructions anywhere that would help me do this.

Thanks

They are not all that bad to do.
The arms are pretty easy but the balljoint is pressed into the hub as well as screwed.
