Front Strut Rattle - SOLVED

[njhtran]

This is awesome that this post is helping people.

Definitely. Even though my problem wasn’t the strut, by taking it off I was able to compress the suspension by hand and find where noise was coming from.

Just FYI guys, there is a long thread about this issue and solution posted quite a while ago:

Rattle noise coming from front Air Suspension (2017-18)

The reason the strut rattle is heard in the passenger compartment is because of how the sound travels through the frame of the car. The fix that I detailed above stops that noise from traveling. It doesn’t change what goes on within the struts. It simply makes it so the noise is not heard...

The sound appeared when the aluminum ring rotated. A couple of weeks before this sound appeared, I changed the lower control arms to Danish Triscan ones. Yesterday, as an experiment, a mechanic replaced the lever with an old one and the clicks went away completely, and the ring stopped rotating!!! It’s not yet completely clear whether these are levers or not, but I’ll keep an eye on it.
By the way, I compared Triscan with the original and at least I noticed that the center distance between the silent blocks differs by 1 - 1.5 mm. Also, the internal hole of the large silent block is slightly smaller and a bolt mark remains on it.

Hey there! I am having this same issue on the left hand strut after control arm replacement. I’m not clear as to what your fix was, do you mind explaining further. Apologies for my ignorance.

Also sorry, do you mean the mechanic put the old control arm in? The arm that attaches to the subframe, the hub and the strut?

Turns out it was a control arm where the center hole that mounts the strut was about 3mm off from the OE part. Swapped it for the old arm and the creak has gone away!

This was 100% a problem with the lower control arm. I don’t know for sure whether this is a problem with the geometry of the lever or a problem with the silent block, which is under the air strut
