My x52 pro (bought second hand) was really clunky and grounchy. I had considered lubrication and had head all the previous solutions. I did intend to buy some silicon lube.
Before I got round to buying the lube I decided to mod my throttle to get rid of the 25% and 75% detents, the little sprung nubbin that creates the detents is swamped in silicon grease inside the throttle so I scooped a little of this up and rubbed it around the base of the stick (soooooo many double entendres) it is now super slick and totally silent - like new!
Beat that for cheap
