its not really that hard. its usually the seals that go out. buy the rebuild kit and have a buddy help you bleed the line. make sure to turn left and right a bunch of times to bleed it while you pump in the fluid.
I just did mine and it wasn't hard at all and plenty of instructions on the web and will come with the kit also. $75 for the kit on ebay with tool and around $25 for a quart of fluid. I RECOMMEND 2 QTS OF FLUID just to replace all the old fluid. You won't see clear come out with just 1 qt.
