My front windshield wiper blades make a soft thump sound at the end of travel (seems to be coming from the right side) that I don't recall hearing before. Any ideas?

 

Mine does that occasionally. In my case it's the wiper tip hitting the windshield surround. Some wipers do it, some don't.

 

+1, same with mine.

 

You guys need to look at the wiper travel. max out to rest. The wiper mount points [single for driver and double for passenger] are secured by 14mm nut. Undo the nut and lift up the wiper. The post in knurled and you can move by one notch and test.
