Is this price fair for tie rods and axel repair?

When I have done front axles on an A4, it was about $350-400 parts and labor. Each complete tie rod assembly lists for $160 and takes about 45 minutes to do, so figure $150 labor plus $320 parts so lets see that is $870 plus about $75 for a 4-wheel thrust angle alignment, so it is a little high. Why not have your old shop look at it. By the way what exactly is wrong with the axle, it is is just a torn CV boot on the axle, they can replace that for about $150 or less, if the joint is not damaged, by the way. I have seen a lot of tie-rods go on the Audi.
