Knocking noise
I have this annoying knocking noise while driving. To me it sounds quite high up and near the cabin, but it could be something in the suspension as well.
https://streamable.com/3ggjb9 My sway bar links were worn, so I replaced them with Lemförder links, but that didn't fix it. However, I have read that some Lemförder parts can be manufactured in China and have questionable quality, but I'm not sure if they are worth replacing again (any brand suggestions?). I also replaced the three strut bar bolts because the center one was not original, but that didn't fix it either. |

Get the car in the air and take a pry bar to check for play in all the bushes in your suspension joints and steering bushes. Check strut top mounts for play too.
