My 2004 impreza wagon has got a leaking powersteering rack , how much labour should it cost to have it change roughly, also is it a hard/easy job?

Thanks

 

I've done a steering rack swap on a 2005 Forester XT (same as WRX setup).

Took a few hours (5 or 6; including down time for required beers); but with the right tools and space, it's not too difficult I didn't think

 

Shouldn't take more than 2 hours on a ramp and some air tools, I would have thought.

 

So £150 labour is a good price to change the rack then?
Thanks
