Why does the new Sagitar make abnormal noises when passing over speed bumps?
2 Answers
Excessive clearance in the steering tie rod ball joint or damage to the chassis buffer components may cause abnormal noises when the new Sagitar passes over speed bumps. Excessive clearance in the steering tie rod ball joint: Excessive clearance in the steering tie rod ball joint can also cause a creaking sound when the car passes over speed bumps. You can lift the vehicle and forcefully shake both sides of the wheel to check for abnormal clearance. A properly functioning tie rod ball joint should not wobble. Damage to the chassis buffer components: Damage to the chassis buffer components can result in abnormal noises when passing over speed bumps. This may be caused by abnormalities in the rubber buffer blocks on the stabilizer bar, which is also a significant reason for abnormal noises when the vehicle passes over speed bumps.
When I first got my Sagitar, it also made creaking noises over speed bumps. After pondering for a long time, I realized it was a common issue. The rubber bushings on the new car's shock absorbers are particularly tight, and this friction creates such sounds when going over bumps. After driving 2,000-3,000 kilometers to break them in, it gets much better. Also, listen carefully to the location: if there's a thumping sound from the front wheels, it's likely due to the stabilizer bar links having overly stiff rubber bushings. If there's a metallic knocking sound from the rear of the car, you need to get down and check the exhaust pipe hangers—VW's design in this area is prone to knocking. Lack of lubrication in the ball joints can also cause squeaking. If the noises are more noticeable in cold weather, it's usually related to rubber components. However, if every bump is accompanied by steering wheel vibration, don’t delay—head to the shop immediately to have the chassis bolts checked for torque. Loose chassis components are no joke.
