Believe it or not, there is a 1 year warranty on a wheel bearing. Anyway...I brought my axel back for my core charge return of $35. Simple and easy. Also brought back the ruined bearing for a refund, simple and easy. I also brought in my hub that I had to replace as a result of the bearing failing, and guess what...Simple and easy. Great customer service by a young man named Julien. Well done O'Reilly's. this was night and day service difference from the O'Reilly's I had to visit on Cave Creek just south of Greenway. Brutal there.
