'01 Taurus Steering Help!

I have a '01 Taurus. The rack & pinion has been replaced three or four times in the past year and a half. The problem that I am having now is the same one as in the past which is leaking fluid. It looks like the leak is coming from where the hoses connect to the rack & pinion. Is there any information that I might could pass along to my mechanic to solve this problem? The hoses and the pump have been replaced in the past. I use the car in my work. I do alot of stopping, and turning everyday while driving this car. Any help would be greatly appreciated!

there are nyon gaskets (look like washers) that NEED to be replaced every time the line is removed - not many people do but it's like rolling the dice if you don't.

Thanks for the information.
