Recently one of the windshield wipers on my HHR stopped moving. I removed the plastic cover and discovered that the wiper arm had become disconnected. One of the little plastic bushings would no longer hold onto the ball joint it was supposed to be connected to. After chiseling off the catches I removed the plastic bushing and figured that it would be no problem to replace it. NOT!
First I tried Dorman kit 49455, they were way too big.
Next I tried Dorman kit 49449, they were way too big.
Next I tried Dorman kit 49447, it is a 10 bushing assortment kit, two of them actually fit the ball joint. The ones that fit were the ones that are shaped like a cowboy hat. To get them to fit on the arm, I had to trim the bottom ridge off to make it smaller. Then a pair of channel locking pliers squeezed the bushing onto the ball joint.
This is what the finished repair looks like.
