So, I added more hydraulic fluid on my 2006 crossfire convertible. The top was stuttering when opening or closing, and the fluid was low. I worked the top 3/4 times and noticed the fluid was down again. I added more fluid, ran the top up and down for 3 times. I noticed the fluid was low again. I noticed on the left cyclinder the insulation was wet with the fluid. Right side some leakage but not as much. Removed both cylinders, I am wondering if just the O ring needs to be replaced and not the whole cylinder. I could not find any leakage from the bottom as it is a closed system. Hoses do not appear to be dry rotted or any sign of leakage. Anyone have thoughts on just replacing the o rings?

Thanks,
Cathy
