Default weird suspension pop noise

Hey everyone I'm having a weird suspension noise pop on my car. I had a similar noise when I installed my front RCAs and it was because they were loose. I had to remove them to put my stock winter wheels on. I reinstalled them along with a new lower ball joint and tie rod end on the driver side. Now when I am at a stand still and I turn the wheel to either side it makes a creaking noise like if something were loose. I reinstalled everything and made sure everything was tight to no avail.
This morning it was raining a little and there aren't really any noises.. Maybe something needs to be greased?

Here is a video of me rocking the car back and forth

I had but I changed them out to the TRD bushings. Maybe 2 months ago.

Check your Sway Bar Endlinks. This was my problem when I had a suspension pop noise as many others have had too.

hmm, It has to be bushing related, narrowing which bushing is the hard part. Can you jack the car up, shake the wheel a bit to see if it make noises?

Being near the noise may narrow down your choices.

Unfortunately it only makes the noise under load so no noises in the air.

So its not a bushing... I had it I'm the air and my mechanic checked everything even retightned everything.. Still the same noise.
Does anyone know if sage RCA's can interfere with ball joints? Sounds weird but I'm pretty sure its the RCA.
I am going to uninstall the RCA from that side and see if the noise is still there.

In my case creaking noise when slightly turning from right to left slowly was the brake pads. Taking out aftermarket and putting back in factory with new fit kit fixed it.

I had the brake pins cleaned so I doubt its the brakes.

How many miles are on your car? Unfortunately, the suspension on these cars becomes a POS after around 140k so you might as well start replacing other suspension parts one by one (maybe one every weekend) and eventually the sound might go away! Ihad my wife's '99 LCA#2, tie rods, and lower ball joint replaced, but a faint noise still comes sometimes over slow humps. I had all suspension parts replaced on my '02 except for upper control arm and I still get a little noise sometimes if i am rolling and turning the wheel slowly on a hump/bump.

I hate these GD suspensions..... but i'm commited to keeping my car for atleast the next 5 years. after that, I'm going to get a car based on prices of it's suspension components (as well as lurking it's designated forum ahead of time to see owner complaints)

I have some Roca Upper control arm bushings that didn't get installed but I might as well go ahead and replace those and see if it helps anything.

Well I already replaced a lot in the front. Minus inner tie rod and upper control arm.
But my mechanic checked them all and none had play. I think its the RCA. Just super busy to remove it and see if it is the problem. Hopefully tomorrow after work I can remove and see of noise is still present.
