I installed "torque nuts" on my sway bar links on the end which connects to the sway bar and solved a noise. The "torque nuts" look like lug nuts with a cone area but are smaller. They fit tightly into the sway bar and prevent noise there. The holes in the sway bar ends are worn out and oversize and caused a clunk noise. I got the nuts at a hardware store.

I doubt the bracket contributes to noise. When mine gets noisy I just replace the bushings and the noise is gone. Have replaced them several times.

On my van the holes in the sway bar are worn out and the holes are too big for the sway bar link studs to fit snugly. The slop causes a noise. I solved it by using torque nuts. The torque nuts look like small lug nuts and the cone shape grips the bar tightly and eliminates the noise.
