I am looking for helpful info on power steering problems in ford aerostar. I own a 1996 aerostar. The power steering is completely gone & every time I put PS fluid in it all drains right out onto ground in less than 10 minutes. What specific parts do I need to fix this problem. Do I need a new PS pump or a seal kit or a pump repair kit? Friends have said the problem is in seal in pump. How do I fix this? Any helpful info will be greatly appreciated, as I have not found any other info. Thanks!
