Have fun. Mine blew a few months ago. You have to drop the subframe to remove it. Then crawl inside, remove the kick panel under the steering column and remove the bolt that pinches the spindle for the rack. I got a used rack for $20 and a case of beer. New ones are easily $200+.
Nope. The leak will just get worse. What happens is the rack ram gets pitted or the chrome starts to flake off and it tears up the seals. Its a common issue. I would not add any stop leak stuff if that's what you were thinking. It could end up ruining the pump. Then your really screwed.
