Steering wheel rattle is a relatively common problem that can be caused by a variety of reasons. The following is a detailed introduction to the possible causes of abnormal steering wheel noise and the corresponding solutions.
1. Steering system related issues.
Friction between the steering column and the foot pads: Sometimes the rear mounted foot pads are too large and are in direct contact with the steering column, so the steering column will have friction when it turns. This is still quite common, and you can adjust or replace the foot pads.
Failure of the airbag hairspring in the steering wheel: Friends who have removed the steering wheel should pay more attention to the fact that the airbag hairspring may be broken or the airbag hairspring plug is not plugged in properly, and the airbag hairspring or fixed plug can be replaced.
The steering tie rod ball joint is aging and has a large space: replace the steering tie rod ball joint, but remember to do four-wheel alignment after replacement.
Oil leakage from the dust jacket of the steering machine: replace the dust jacket or re-butter. However, buttering is only a stopgap measure, and it is recommended to replace the dust jacket as soon as possible.
Steering machine failure: If there is a "cluck" sound when playing the direction, it may be that the gear gap between the steering machine and the gear is too large, and the steering machine can be replaced.
Plane bearing top rubber failure: when the direction is called, there is a "special tete" sound, it is likely that the shock absorber top rubber or plane bearing failure, you can replace it.
Improper tightness or aging of the power assist belt: For the mechanical hydraulic power assist system, if the belt tightness is improper or aging, there will be abnormal noise, and the belt can be adjusted or replaced.
Stuck due to bending of the steering shaft and casing: this is caused by excessive force, and it usually occurs in drivers who "work hard and miracles". The solution is to replace the steering axle and casing with a new one.
Second, the suspension system related issues.
Loose hem arm ball joint, too large gap: Tighten or replace the hem arm ball joint.
The rubber sleeve of the balance bar is loose and the gap is too large: tighten or replace the rubber sleeve of the balance bar.
Aging and wear of shock absorber top rubber: replace the shock absorber top rubber.
Shock absorber oil leakage, damage: Replace the shock absorber.
Loosening or damage to other parts of the suspension system: Tighten or replace the relevant parts.
3. Tire-related issues.
Tire wear is uneven or tire pressure is too high or too low: Do wheel alignment or replace tires, and adjust tire pressure.
The front wheel alignment is inaccurate or the toe is too large or too small: do four-wheel alignment to adjust the front wheel alignment and toe-in.
Damaged or badly worn front wheel bearings: Replace the front wheel bearings.
Front hub bearings loose or damaged: Tighten or replace the front hub bearings.
Front Tire Bolts Loose or Damaged: Tighten or replace the front tire bolts.
Excessive or heavy wear of the front brake clearance: Adjust the brake clearance or replace the brake related parts.
Poor dynamic balance of front tires: Redo the dynamic balance of front tires.
Front wheel bearing boot damage or oil leakage: Replace the front wheel bearing boot and refill with grease.
Loose fit between the front wheel bearing outer racer and the housing hole: Replace the front wheel bearing outer racepiece and repair the housing hole.
Loose fit between the front wheel bearing inner seat and the journal: replace the front wheel bearing inner seat and repair the journal.
Fourth, other problems of the chassis.
Loose or damaged chassis screws: Tighten or replace the chassis screws.
Loose or damaged chassis components: Tighten or replace the relevant parts.
Loose or damaged engine and transmission brackets: Tighten or replace the engine and transmission brackets.
Transmission shaft bent or damaged: Replace the transmission shaft.
Loose or damaged exhaust pipe lugs: Tighten or replace the exhaust pipe lugs.
Shock absorber spring deformation or breakage: Replace the shock absorber spring.
Engine and transmission pads are aged or damaged: Replace engine and transmission pads.
Loose or damaged fuel tank set screws: Tighten or replace the fuel tank set screws.
Loose or damaged rear axle assembly components: Tighten or replace rear axle assembly components.
Inaccurate wheel alignment data: Redo the wheel alignment and adjust the relevant parameters.
5. Summary and precautions.
Before proceeding with any repair operations, make sure that the vehicle is completely cooled down and disconnected from the power supply to prevent accidents.
If you are unsure how to proceed with the repair operation, it is important to consult a professional or go to a regular workshop for inspection and repair.
