I'm submitting this post in hopes of helping someone else. For the past several months I have had a clanging sound coming from the front of my 4Runner every time I hit a hard bump. I looked at everything under the hood and couldn't find the source of this rattle....until now. The source of the clanging was the shackle on the front. If you're having similar sounds, check the shackle. To fix the problem I added rubber washers.
