2004 mustange convertible TOP HYDRAULIC CYLINDERS

I am having trouble RAISING my Convertible Top.  The Motor seems to be working but the top raises very slow and I have to HELP IT to completion.

I believe I may need NEW HYDRAULIC CYLINDERS and/or FLUID ADDED to the exisiting cylinders.



ANY THOUGHTS? or ANYONE HAVE A REPAIR SERVICE TO RECOMMEND (other than a ford dealer)?



thx SUE MANN
