When putting down the top on my 2008 convertible, a squealing squeak emits from the right side. I lasts for the entire trip from closed to the upright position, about 3 seconds. There is no squeak on the cover's trip back down. Thinking it might be the gas strut, I lubricated the rod with silicone grease with no change in the squeak. Your thoughts, please.

Thanks,

Dick S.
