“Replacement of cv joints- october 2018 my vehicle was diagnosed with leakage from the cv joints which splattered all underneath my vehicle. My vehicle only had 69,000 miles. The technician stated that they should not have been a problems with so few miles. He stated that my vehicle's steering would have been compromised if they had failed and cause damage to my engine. I travel 1 hour one daily to work. It could have caused a potential accident if it hadn't been diagnosed in time. It has been since then repaired.”
