03 2.0 Steering rack - fago
Previously on this forum I got excellent information when my diesel engine in my mazda 6 blew up after 6 months.

Anyway, the pain continues.

The steering rack has started leaking. From what I've been told it has to be replaced as a unit. Mazda's price for the part ?1,600 + VAT in a Irish dealer.

Any recomendations on other sites where I might source this part for a somewhat less crazy price.

There are people in the UK who rebuild racks, but it would be awkward for you due to shipping costs and your car would be immobile whilst waiting for the repair.
How about finding a written off car (ideall one with side or rear damage) and taking the rack?

Can I suggest you make a few queries for Mazda parts in New Zealand. Over here they are relatively more common than Fords or Vauxhalls are in the UK. A steering rack can probably be sourced for a few hundred pounds including the shipping. You could try: www.mazlinepartsworld.co.nz The exchange rate is over 2:1 in your favour so there are bargains to be had, and there is probably more experience in Japanese cars over here.
