Hello everyone. I have a weird issue, and need some help. I have a 2018 GX460 with 60,000 miles on it. I noticed today that i hear and feel i thumping noise from under the drivers side. This happens accelerating, braking, turning, etc. I can literally feel the thump at my feet when driving. It almost feels like a large rock is getting thrown from my tire and hitting the inner fender well. I run BFG KO2's, but i have verified there are no rocks are stuck in my tire. This happens at random times. I have searched a few threads, and some people had said to replace the sway bar bushings. Any advice is appreciated.
