I have had 2 of my hydraulic cylinders start leaking(folding top, main cylinders). I haven't taken them out yet and I can get the up and down manually. My problem is were the special tool goes? The pictured diagram on the Forum shows the slot going left to right and mine goes front to back. I climbed up on the back (ladder) and, using a flashlight look in the slot. I could see no place for the 10mm special tool to go to unlock it, or in this case to lock it. I can raise or lower the tonneau and with the top cover locked in place there is no problem. What concern me is if I put the top down and drive along at Interstate speed is the tonneau cover going to blow up? Any insight on this situation would be greatly appreciated.
