Same thing happened with my 2016 Emax22S. Sent in pics on TractorByNet. Got advice. Sprays didn't help much over a couple of months. Finally used controlled propane torch heat and progressively increasing tapping with a hammer with loosening after 15 minutes. Cleaned/polished everything wwith emery paper and gun barrel brush and put copious amounts of lithium grease. I wrote this up in early 2023 with pictures.
