It's no a technically difficult task to install bushings, just time consuming. I'd give youself 2-3 hours at a time and work on 1 set only.

I've done bushings on my Nissan and still in the process of installing them. I doubt I'll install them on my Focus.

The only annoying part is having to grind out the rubber bushings that tend to stick... Well, this only applies to older cars with worn out rubber bushings. I use a file or sanding bit to wear down the excess material, do not grind into the metal.
