A couple of years ago I had the same problem. I removed the top filled with new hyraulic fluid worked for about a month. Found fluid on drivers side. Removed top found hydraulic hinge bad. Replaced worked fine until passenger hinge failed. Removed again replaced hinge then top would not come down as fast as before. I felt that maybe I must of kinked a line? Removed top inspected no kinks. Tested pump and purged system. Top has always gone up fast and still does but will not go down unless assisted. My son is tired of helping me remove the top. I am good at it and its not a bother. I think I might have bad seal in the pump assembly. I wanted to remove it and see if there is a obstruction in the system(down cycle). Has anyone taken the assembly apart? I know if I buy a new motor and pump it will be fixed. Just asking?
