Did you grease it a couple of years ago when new?
But most don't think that 'too much grease is bad'....in most circumstances, unless the floor of the shop already has a grease spot from too much.
Sorry I didn't see this post until now.
I did remove the cable and lightly greased it with white lithium grease when I installed it back in 2022. Since it's been working now for about 300 miles, I think I'll leave it alone unless somebody says I need to pull it out and add more/different lubricant.
