Steering all 22 →
Original owner of a 2007 Buick Lacrosse cxl. Power steering pump failure at around 85,000 miles. Power steering pump failed because of leaking hoses. Primary reason for leak is due to lines incorrectly crimped around the metal line that adheres to rubber hose. Lines cannot withstand pressure and start leaking intermittently until they completely fail. I have replaced power steering pump and rack and pinion due to faulty lines damaging the whole system. I have seen many instances online about people having to replace a couple months later after initial replacement. This is a manufacturers defect of power steering lines that are out on the market. Another issue is the clunking sound that is coming from the steering column.
