2007 dts wiper noise
 

When the wipers change direction there is a clunk. Has anyone else heard this. Seems to be to loud for a caddy. This is my fourth one and i really didn't notice it on my other ones. I pulled the cowl screen and all the wiper linkage appears normal, wiper motor is tight and all of the wiper motor mounting plate bolts are tight. Seems like mayber to much noise from the wiper transmission.
