Why did both rear wheel bearings go bad (@ 63, 000) causing replacement of them plus entire axle due to damage? Seems odd for such severe damage to have occurred with such low mileage. Our mechanic says (& Knechts Auto parts confers) that the bearings could have been low grade/quality (China) from factory. Whatever...cost $1100.+ for repairs. This needs to be investigated and reimbursement allowed.
