I recently changed the steering rack, tie rods , control arms,struts , ball joints , sway bar links, brake pads , rotors, calipers and it was all over the rd after alignment so I went to out it on a trailer to take it to a diffrent machanic and the passenger outer tie rod fell off , when it fell it busted my cv axle boot . I got a whole new axle from napa but it was smaller in diameter and the machanic said it wouldn't matter it was a good name brand , then I got another alignment. Now the car drives great no clunking great steering and ride no clicking or loss of grease or power steering fluid but it has a rather loud roar to me on the same side . Us ut diferential issue or possible bad hub bearing ????
