Hi all I'm looking for some advice. Recently when the car goes through uneven ground there is high pitch noise squeaking. You can clearly hear the noise in the video.
Not the knocking sound but the "it it it..." sound. Is there anyone experienced the same problem? Any help would be apperiated. Thank you.

 

Interested, have something similar/same. Guessing it’s a suspension thing, bush etc

 

There is a lot going on there. Could be anything from droplinks require tightening up to something else bigger.

Anyway, looks like you are from Hong Kong too. You could check with your shop’s technician on that. Or there are a few shops that are reasonably familiar with these cars. They might be able to help you out if you are doing service with them.

Good luck!

 

Haha! I have this same damn squeak issue. It's even better when the sub hits certain frequencies or db and amplifies it (sub in the back).

It's definitely coming from the back. I have not been able to spend enough time to figure this out, so I am going to watch this thread closely.

 

The most common noise is caused by dry suspension ball joints on the lower control arms. These either need greasing (a very good test) or replacement.

 

Would White Lithium spray work to lubricate?

 

Idéalement, retirez la roue concernée, insérez un petit tube et injectez de la graisse ou un liquide huileux dans le soufflet de rotule. La lubrification externe est inefficace.
