- While performing a prealignment inspection: Technician A says that improper front-wheel bearing adjustment may affect wheel alignment angles. Technician B says that worn ball joints affect only the camber angle. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardWhile driving straight, a FWD car pulls to the right. The most likely cause is. more positive camber on the left front wheel compared to the right front wheel sagged front springs and improper front-wheel toe setting less positive caster on the right front wheel compared to the left front wheel the SAI on the right front wheel is 1*A degrees more than the SAI on the left.arrow_forwardHow does a technician determine the proper inflation for a vehicle's tires?arrow_forward
