2013 Raptor Crew Intermediate steering shaft issue

Hello,
Need your help. 2013 raptor with 65kmiles and mid perch lift.
At 58k miles, felt popping or binding in steering wheel when turning, especially when turning on inclined or declined scenarios. Researched and figured it was my intermediate steering shaft. Sprayed WD40 and it went away. Now I am spraying Wd40 every 5-10 days. Should I replace the shaft assembly or do I have a bigger problem? Any help is appreciated. Thanks! RH

I also have a 2013 w/ 78000k miles that is also giving me issues when turning at low speeds. I just had the entire steering rack replaced. Out of curiosity, did you ever change the steering shaft?
