Wiper arm linkage bushing FRUSTRATION!

If you can get a larger flat head screw driver in there and pry it up off of the stud. You might damage the bushing by taking it off but I don't think you will get the arm back on the bushing right with the bushing on the stud first. I picked up mine from Oriley's the were $2.99 for two. Good luck and take your time.
