Had this happen to me last winter. You can take the drive shaft (pilot shaft) off and just have front wheel drive until you get a new one. I ordered one online I think it was about $300 to the door. When I did it I cut the shaft down to a nub so you can bolt the yolk back up to it so the mating surface does not corrode.

 

When you get around to putting a new shaft on you might want to think about changing the "differential" fluid. I forget what they call it. It is very dependant on the fluid being in tip top shape to activate the all wheel drive.

 

 

The crappy part with these drive shafts is they have non serviceable u joints that are staked in so you can't replace a u joint for $15 when they start to go. I think doorman or someone makes an after market shaft that does have serviceable joints but it is a little pricey.

 

 

i'd go oem used ! everything oem seems always more reliable than aftermarket, same goes for cv axles

 

I guess I do a cost benefit analysis first. My 02 has 270,000 miles on it so it is hard to justify the super high cost of somethings oem. Also I would only buy a used drive shaft if I could replace the u joints which honda made that pretty much impossible on these vehicles. I tried and ruined a bunch of tools attempting to remove the u joint. The failure point is the u joint so buy used you are just buying a high mileage u joint.
