Popping noise after replacing many suspension parts
So I recently replaced:
Upper and lower control arms on both sides (front)
Tie Rods inner and outer
Front struts
Strut mounts
Sway bar bushings
Sway bar end links
I also just got the car aligned
It is making a weird popping noise when turning the wheel to the right while being stopped or backing and then turning out of my garage. I double checked to make sure everything was tight and torqued to spec. I even had my girlfriend turn the steering wheel while it was on the ground and found nothing that was making the noise. It actually sounded like it was coming from the middle of the car. I had my skid plate on so I couldnt check that but I will later when I get home. I also remembered that I never greased the bushings. I didnt think it needed any but could that possible be the issue?
Any ideas as to what could make this popping sound? Only happens when turning the car to the right. I am at a loss as to what could be causing this.

I've been reading about replacing the lower control arm because I need to change mine. One thing I remember was you need to tighten/torque some bolts after the car/suspension is lowered, otherwise it will stress the bushings. I don't know if that's causing the popping sound but..
BTW if I may ask what brand LCA did you go with?
Edit: my issue is with a Honda Pilot, not the C240, but it could be similar issue.

Check the control arms to make sure they didn't slide out of the bushings (on the subframe end) and rubbing against the subframe. This can happen with a defective arm.
