My c v joint split near the tire.

It'll require partial suspension disassembly. Lower control arm, sway bar, and steering joint needs to be disconnected. If you have an impact wrench, that'll make the job easier, when you bust the CV nut loose. Everything will swing out of the way. DO NOT touch any of the strut fasteners, otherwise you'll need an alignment. Most auto parts store will let you borrow or rent the CV nut socket and specialty tools you'll need to do this job.
If road debris has already entered the CV joints & grease within, that half shaft may fail within the next year or two. Popping, scraping, and howling sounds. This is why most shops will only warranty a half-shaft replacement; not a boot replacement.

Hope this helps....

FYI: If you have issues reassembling; try rotating the half-shaft while pushing back against the transmission. Sometimes the knuckle on the other end of the shaft gets dislocated, That why it looks like it won't fit back together. Once everything gets realigned, everything should lineup and bolt back up. Reassemble in reverse order.
