Apparently Honda will warranty any rear wheel bearings upto 7 years old ........ ask at your local dealer.
We replaced the offside rear bearing on our 2003 1.4SE in 2006 at 29,000 miles, now it has failed again at 49,000 miles. Would the new bearing be covered under the 7 year warranty, it was a honda part?
Our local garage who fitted the last bearing replacement, confirmed that the replacement had failed!! at 49000 miles. He phoned arround for me & found out that Honda have now extended the warranty on this fault to 9 years.
We took it to the Honda dealer where we purchased it in 2005 & after some arm twisting & quoting details with bills to prove the case, they checked it out at no charge & are replacing it next week FOC

So don't give in keep fighting. Oh evidently Honda do not accept the views of forums like this as they say they can be malicious. Fine but why don't they come clean when there is a problem.
