Annoying Speedometer Noise at Cluster

The noise is coming from the speedometer head bushing. You can try a light oil, not wd40. Remove the cable and lube the back of the interment cluster where the cable fits in to. Might work better if the cluster is removed from the car and face down. Don't use too much oil it will just make a mess. If it helps, your in luck, if not, it is time to have the speedometer rebuilt.
