Steering and Suspension Final Exam Questions With Verified Solutions.

Steering and Suspension Final Exam Questions With Verified Solutions. After new tires and new alloy rims are installed on a sports car, the owner complains about steering wander and steering pull in either direction while braking. Technician A says there may be brake fluid on the front brake linings. Technician B says the replacement rims may have a different offset than the original rims. - answerTechnician B Technician A says when a vehicle pulls to one side; the problem may be caused by a pinion gear binding on the rack gear of a power rack and pinion steering gear. Technician B says when a power steering rack and pinion steering gear spool valve binds it may cause a vehicle to pull to one side. - answerBoth A and B The outside edge of the left front tire on a front-wheel-drive car is badly worn. Technician A says the cause could be worn ball joints. Technician B says the cause could be that the camber setting is excessively negative on the left front suspension. - answerTechnician A The owner of a 2-wheel drive pick-up says the front tires squeal loudly during low-speed turns. The most probable cause of this condition is: Excessive positive camber. Negative caster adjustment. Improper steering axis inclination (SAI). Improper turning angle. - answerImproper turning angle. A 2-wheel drive pickup has a severe shudder when the vehicle is started from a stop with a load in the bed. Technician A says the problem may be worn spring eyes. Technician B says the problem may be axle torque wrap-up. - answerTechnician B Steering pull to the right occurs only when braking. The most likely cause of this problem is: Excessive positive caster on the right-front wheel. Excessive positive camber on the left-front wheel. A loose strut rod bushing on the right-front suspension. Excessive toe-out on the right-front wheel. - answerA loose strut rod bushing on the right- front suspension. Technician A says hard steering may be caused by low hydraulic pressure due to a stuck flow control valve in the pump. Technician B says hard steering may be caused by low hydraulic pressure due to a worn steering gear spool valve piston ring or housing bore. - answerBoth A and B Technician A says incorrect wheel alignment angles will reduce tire tread life. Technician B says wheel alignment is necessary after ball joint replacement. - answerBoth A and B While discussing tire tread wear: Technician A says a scalloped pattern of tire wear indicates an out-of-round wheel or tire. Technician B says uneven wear on one side of a tire may indicate radial force variation. - answerNeither A nor B Technician A says excessive front wheel bearing endplay may cause steering wander. Technician B says a defective front wheel bearing may cause a growling noise while cornering. - answerBoth A and B A vehicle pulls to the right when driving straight ahead. Technician A says the right-front tire may have excessive radial runout. Technician B says the right-front tire may have a conicity defect. - answerTechnician B All of the following could cause shock absorber noise EXCEPT: A bent piston rod. Worn shock absorbers. Shock fluid leaks. Extreme temperatures. - answerShock fluid leaks. When a vehicle pulls to one side, any of the following problems may be the cause EXCEPT: Worn ball joints. Reduced curb height.
