I saw a video where a guy removed his front wheel spindles and installed needle bearings on the spindle then reinstalled them for easier steering.
My question is... His spindle was removed by removing a cotter key. I want to do this HOWEVER my spindle does NOT have a cotter key. it appears to be welded . Any thoughts on this
How can I remove them.. I already purchased the needle bearings before looking. DUUUHH. This install would be on a 2016 Cub Cadet XT2 Lawn Tractor

thanks in advance
