Hi guys,Front right been noisy. So I did this: -1. replaced mounting (causing knocking sounds)2. replaced absorber (reason for a koyak mounting)3. replaced absorber link (caused by koyak absorber)However, after having done all 3... there is still noisecoming from front right.Back to the workshop and they identified the undercarriagecover as the cause. RM500 for a brand new.Need recommendation for cheaper option.Can advise?Thanks.spec.check
