E83 wiper linkage
 

I just did the wiper linkage on wife's X3, went with the Vaico unit and was happy to see that is improved with bigger shafts than the original! :)

Once again, if there had been a little bit of grease on the metal shaft, even though it's a plastic bushing, the original probably would have lasted the life of the car.

Haha, I keep forgetting the car is 20 years old and probably has another 20 years of life left! ;)
