Ok so I hit a pothole one night and immediately started hearing a loud knocking noise from my front passenger side. I replaced both passenger and driver air shock struts and noise was still there. I replaced the upper and lower control arms and the tie rod ends to both passenger and driver side and the knocking noise is still there!! I hear it when I go over big and small bumps going fast or slow. I don’t know what else to do but I don’t want to keep buying replacement parts because it’s starting to get pricey. Does anyone have any suggestions?

Just keep on throwing parts and $$$ at it without knowing what for.

Get your largest, heaviest friend who is physically able to help. Use wooden blocks or something similar (NOT hollow concrete blocks!) to go under the front tires. Jack the car and put the supports under the tires. Make very certain that the car is safely supported - try to knock it off the blocks! Get a good flashlight. Get under the car and watch closely on every joint, bushing, point of attachment, etc., etc. while your friend tries hard to bounce the car. Look for any signs of current or past movement. Check for any cracks or breaks in the structure. If it is making that much noise, you should be able to find something. Don't forget where the tops of the struts attach.
