Price the job around. You should be able to get it done for less than 1100 dollars.
It’s really not feasible to replace seals in a leaking rack for several reasons. Generally speaking, you can’t even buy the seals needed as they are simply not available.
Many of these seals are specialty hard seals that are very delicate and special tools are required for installing them. Finding the tools needed is often difficult if not impossible.
Add in dust boots and replacement of both inner tie rods which are more than likely worn and even if one had the tools and seals in hand it’s just not cost effective to repair a rack; assuming it could even be repaired and the spool housing is not grooved up.
