Hey, Bryan!
This is Fast Freddy
Just weld it and you’re good to go, no biggie at all
It probably cracked from going too fast, I noticed as I couldn’t catch you
Something had to give Lol. ( Man you were flying!!! )
Another thing to look for is your spindle bearings, they do brake, remove the tie rod ends from spindle and move the spindle side by side, also make the tire straight, grab it and try to move it up and down, if it has significant amount of play
Replace the spindle bearings and king pins.
Hope that helps?
Good race, last Saturday night, Buddy, good job.
