well the po before me pulled the cv axels out when the diff locked up and took the outer cv joints off the axles and used them as plugs for the hubs, so the bearings in them are junk, and ive found replacement ones for 40 shipped a side with a 1 yr warranty,Sometimes, ebay isn't the cheapest place to purchase. You've got to look around, also consider freight rate in the purchase price.
While i've have good luck with the cheapy cv joints(the whole assembly) off of ebay, bearings was not a good idea. You could look up pats small engine parts and see what they have, other dealers as well.
