Not if you do it yourself. I'm sure there are write-up on here, and if not, there are probably members willing to walk you through it. If that isn't something you are comfortable doing, the cost will depend on where you take it. I'm sure others on here will be better able to give you an idea what a shop would charge for this. My guess is a couple hundred bucks, but that's purely a guess. It would mostly be labor, as the seals are probably around $20.
If you give your general location, you may find that there is a local member willing to lend a hand. Cannot promise that, but you never know.
