you will need to strip front suspension,remove caliper and disc,hub nut and the shaft can be removed,it will be easier to repair on the bench,if the ring is damaged you may have to obtain a complete joint as they come as one unit,had a ring split on my own car a few months ago and managed to braize it together and very gently slip it back onto the joint and re inforced it with a good glue and some sealant and its been fine since
