Technician A says that play in the steering gear is the probable cause of a shimmy. Technician B says that it could be loose steering linkage. Who is correct?
technician a says that camber changes as the suspension moves up and down. technician b says that camber changes as the vehicle is loaded on the suspension sags under the weight. who is correct?
While discussing steering problems: Technician A says that a “jerky” steering wheel and a “clunking” noise could indicate worn steering column U-joints. Technician B says that lack of assist and a “growling” noise in a fluid-filled steering pump could indicate a hose or pump internal restriction. Who is correct?
