im proud to say that as a very amateur mechanic i changed all 4 boots myself (the second two i had an extra set of hands making it much easier) - when i called places to ask if they could do it for me noone would even consider it unless i bought new axles - could not find anyone (at an actual business) that would change just the boots
side note: im pretty sure ldub found an aftermarket axle replacement from suretrak that seem to be doing well for people as a replacement for stock
