Chassis system Sincerely convinced front engine room should be removed first. The rubber sealing sleeve does not need to be removed during the inspection process (no damage to the rubber sealing sleeve or assembly state caused by any operation is allowed unless it is specially necessary). Tools: torque wrench, clamp clamp, screw driver, etc. Specific steps and fault diagnosis: 1.Check the air pressure of the four tires. 2.Lift the front of the car and support it with struts. 3.Visually inspect the appearance of left and right steering tie rods, whether the ball head thread (with cotter pin) and connecting nut are damaged or loose (whether the marks are aligned); 4.
Check whether the rubber dust cover is damaged and whether the clamp is loose or falling off; 5. Turn the steering wheel slowly to the left and right, and visually check whether the ball joint of the tie rod is obviously loose (clearance and movement). 31 Fault type Maintenance method Tightening torque Remark Thread damage Replace —— Repeat the front wheel alignment test Loose thread Retighten Ball thread: 45 ± 5nm Connecting nut:
