Is there 'how to' guide to replacing the steering rack and front ARB bushes on a FWD A3 anywhere?

I did intend on paying someone to do all the bushes on my car but rapidly running out of money so going to tackle them myself a bit at a time.

I assume fitting the steering rack bush is basically the same for all A3's including S3's, presumably the ARB is slightly different on a FWD compared to a Quattro and S3.

Any hints and tips would be appreciated
