You need to know three things:
– Wheel diameter, which might say on the rim or the tire.
– Axle width, which will need to be measured.
– Number of cogs, the shifter will tell you that. (F/W or cassette style?)
Lots of variables that can make the wheel work or not, it might be best to have your local bike shop give you a hand so you know for next time.

Do you know with 100% certainty that the hub actually needs to be replaced? The reason I ask is, replacing a hub is not a trivial job. You would basically be building a wheel, and wheelbuilding is a skill that takes a fair amount of practice and experience. Don’t get me wrong, I’m not trying to discourage you in any way. But in many cases when a hub is no longer serviceable, the path of least resistance is to just replace the wheel.
