Ok here's the update. So far, I've changed the sway bar links, front strut mounts and struts and the noise is still there. Sounds like a clanging sound on the front driver's side and only seems to happen on really rough roads, with potholes. There's a big difference on the way the left hand side of the truck handles the roughness vs the right side. Mechanic checked the control arms and they're very tight.

Any ideas what this could be?

BTW, the KYB struts worked out very well for a third of the price of OE.
