OK I've posted this before but the experience has just got worse... so I thought I would update to hopefully avoid anyone else making the mistakes I have made... I know I'm always the first one to say for certain parts its best to use only genuine parts - on this occasion I didn't and I wish I had...
About a year ago I changed a rear wheel bearing on my XC90, I was contemplating upgrading the car so I bought the cheapest bearing on e-bay. This one to be precise:
https://www.ebay.co.uk/itm/VOLVO-XC9...AAAOSwbkVaFrcz
Fitting it was a nightmare, the old one came off okay but when I built it back up - the wheel was locked. Turns out that the hub casting is a slightly different shape and it was fouling the parking brake back plate on one side and hence not seating correctly - net result was the brake disc/hub face was skewed. Had to strip down again, remove and cut the brake back plate..... took 3x longer than it should have.
Anyhow.... 9,000 miles and 10 months later the bearing has failed. Noisey, rough running, etc. No problem I thought has two year warranty. Seller led me on a wild goose chase for 4 weeks asking for a letter saying how it was fitted, then how it was diagnosed, then stopped answering all e-mails with no explanation. Got e-bay involved, they wont enforce warranties. After e-bay's intervention I got an e-mail from seller saying warranty claim declined as insufficient description of fault given which is nonsense and they're not replying again now. A full description was given including driving, ground up wheel tests etc.
So based on my experience of the poor quality, fit and fractional lifespan of the goods, and then the shyster behavior of the seller towards their claimed warranty period in the contract of sale - I will be avoiding all parts from e-bay seller Buhuha. For me it has been a costly and expensive mistake and they are clearly not a company of principles.
