I recently had a few things done on my car, and was told I had no power steering fluid in my car. They charged me $69.99 to replace the power steering fluid.I didn't notice this until I got home because I had a number of things done.t's hard being a woman and not really knowing what's needed and the reasonable rate. ANSWER by Visitor on July 10, 2010. well...power steering fluid costs about $4.99 per bottle and a bottle is enough to fill it up..but a flush costs about $30 plus labor so yea.. Upvote (2).
