I bought a 2005 Equinox in April 2006 with only 23100 kms (14438 miles). In May 2008 at 43270 km, I had to replace the left front wheel bearing (BR930326) and associated link-kit; I paid $394.22. In April 2009, at 51172 km, I changed the same bearing of same wheel again as well as the link kit; the kit was replaced for free because of its warranty, but I had to pay the bearing $310.30. In September 2009 (only 5 months later), at 56000 km, the problem appeared again. The exact same bearing had to be replaced; this time however the warranty covered the costs; I only paid one hour work. Just recently in January 26, 2011, the same problem appeared once more. It had to be preplaced and the warranty was not acknowledged; so I had to pay $396.05. What is wrong with this e bearing. Is this a common problem for the Equinox 2005. What can I do, given this sequence, I d expect to replace the bearing once a year.
