Power steering leak
 

My power steering leaks I've replaced the lines now I'm going to try to replace the power steering rack to my 1990 Lexus LS400 does anybody have any input on what I should get or use problems something to avoid also I was wondering if I should just replace the power steering pumpbut the leak seems to be coming from the on the driver side so I think it's the rack plus I'm on a tight budget thanks
