For the other member goodluck mon,first thing no doubt its a warranty issue,then try very imprtant try to have them due both sides,cause you dont want to go through the hassle again if the other side goes bad down the road,i personally think its the wheel hub assembly,but my last visit to the dealer for the same issue,they stated and printed a copy of the part tht needs to to be specially ordered is the washer for the cv joint,i guess for them its cheaper and less labor than doing the wheel hub assembly,also want to make sure they do a wheel alignment.
