“Having issues installing cv axle on Corolla. Seems like the parts doesn’t fit but im not 100 percent sure as the old part I took out looks like I ripped it out causing it to look longer, but I’m having issues fitting it into the bearing I think its called and the sway bar link is up against the cv boot.”source ↗
