My stock one failed ~7 years ago (@~7 years old). The main arm fell loose, so I made it a uniwiper 
That was temporary, I replaced the whole mess shortly after. But the new-er one is failing too, ithas not fallen off yet, but it has lots of slop. I don't remember what I used, but I just ordered a Dorman.
I'm just wondering how often should I expect this. So far it looks like they only last ~7 years, that's about 3 years short of an acceptable design.
