Strange brake/suspension issue (moan/groan from front end)

[ShyBoyCA6]

doesn't sound lubricated enough to me. did you have this with the other engine in it? B18 or A20? what about the inner bolt for the lower control arm? is it torqued to spec? Also by the sound of it and the only place i know that could possibly make that sound is the front crossmember i could be wrong but there is a washer type thing that holds the bushing in place. The name slips my mind -_- it could be slightly lose to make the noise. great vids btw always wonder how things moved down there when your driving and holy shit is there alot of moving parts hahah.

I know right, the pinch fork looks like rubber, and the bolt looks loose. Optical illusion.
The roar reminds me of input bearing/shaft noise, so did the clank now that I think of it ...on domestic trucks though.

I may check out unbolting the lower arm, lubing, and re-installing the lower control arm. That is one thing that I have not removed (since it has poly bushings). As far as before the swap; I have no idea, this car has only been driven once with a a20 by me lol.

To me the pop sound is a axle but the other pop sounds like a strut rod or bushing problem . Btw awesome vid

That pop was some random occurrence, not fully sure. I'm gonna do some more vids, I'm interested in what the back looks like while moving lol.

Ok I think now maybe I hear the brake pad rattle clips. They might be catching the rotor edge.

The other bad thing is a bad bearing or a snapring floating around.

Alright I'm really leaning towards the brake booster as the failure. For one I have developed an idle haunt issue that I can alleviate by pumping the brake pedal. I went through all the procedures in the manual to check it, but they all came out ok. The noise now happens even when not moving when the idle surges. Here is a video, you can hear it clearly at 51 seconds and every time the idle comes down until I release the brake and start moving. I'm thinking the diaphragm inside the booster is what's making the noise.

disconnect and plug the booster vac hose and see if that gets rid of the noise and idle fault.
had a funny idle problem with an old car, disconnected the booster, no more problem apart from hard as brakes
