When I work the soft top, the pump works but all the fluid flows right out in area right in front of both rear wheels.

What is likelihood that I develop a leak in the lines on both sides at same time? Any chance it's some check valve not closing?

found out what the problem is? i'm kinda in the same boat. local dealership said i may have to change all of the pistons (12 or 13 i forget) at 200 bucks a pop. anyone else have any ideas or suggestions?

Diagnose the problem to leaky piston valve units on both side. With top down, if you lift the rear deck cover you will see the top mechanism and arms. There is a silver/gold mechanism in center and a small piston that sticks out connected to the top links, the fluid is leaking thru there.

Checking on price for part now.

You have described the fabric bow hydraulic cylinders, asian. Price should be about $150 each through the Internet, and if you wanted to you could easily replace them yourself.
