Mine is about 5 inches long, 4 might work.
I was never able to get them out using a punch. The spacer inside the wheel does not allow you to get a good bite to be able to drive out the bearing.
I bought one of theses years ago; Bearing Remover Set (http://www.rpmracingca.com/proddetail.asp?prod=Tools%3ABearingRemover)
We use it regularly and it make all wheel bearing removal easy.

Wheel bearings can be a PIA using a punch and hammer. The inner spacer can cause problems. IMO ordering the Bearing removal kit from RPM is the ticket,

I have the kit and it works well. Also for installing the new bearings, the Harbor Freight bearing installation kit works very well. I have been a mechanic or electrician my whole adult life. I am a firm believer that if there is a specific tool to do the job, then use the correct tool. Spending hours trying to cobble something together often leads to frustration and possibly damaging valuable parts.

Fred, there are not too many truer words.
I have a bearing race driver in stock but for some reason it has dropped off from the website. I will get it re-loaded and post the link when it is back up.

I was able to get the bearings out with a punch. I bought a 7" punch and a 9" punch at the used tool store. $7 for both.
It is not hard with a punch. Either size will work. The hard part is relearning the technique as the last time I did it was several yrs ago. One has to shift the spacer over as far as possible to expose the edge of the bearing. Use a screwdriver for that. The spacer may only shift 1mm or so. That is not much, but you will see the edge of the bearing now exposed. Flip rim over, put punch in thru the spacer on the exposed edge of the bearing. Bang, bang with a hammer and then shift the spacer to expose the 180 degree opposite side of the bearing edge. Back and forth a couple times, out comes the bearing.
Once out, one bearing felt perfect, the other side was getting gritty and not smooth. I had added grease 3 yrs ago to them, but it was on my mind to replace them. I am at 50,000 mi. And I plan on doing some "How fast is this bike anyway runs" so lets have everything in order first. Now the new tire, etc.
I've used a long extension several times with not too much trouble.
