Notes this down. Yelling sometimes worksI yelled at him to finally threaten him i am not paying until you cured the issue. And there we go :)
Compared to the power transmitted by the engine to the rear wheel, how much power can arm wiggling transmit? Wiggling test only good for badly worn arms; generally stuff which driver should be able to feel at low speeds. Let's say if rear wheel bearing is making a bit of noise. I dont think wriggling is able to detect that; not unless your bearing is about to fall into piecesYeah, most mechanic will jack up the wheels and use hand to rotate and confirm about the issue.
