Upper A-arm bolt removal
try a small right angle grinder with 3 inch thin cutting discs
be careful not to cut into frame, arms, or fenderwell!!
4.5 a bit big, cutting discs,
if ya have a rotozip with flex head attachement , that shoud do good as well
upper ball joints be a bastard to get out too
if they are put some heat on it use a strong impacy wrench as well,
dont forget a can of rust eater!
