wiper linkage problem

[ad356]

so i went to the junk yard yesterday. i picked up a used motor because the last motor i got would not park. so the motor parks and operates correctly, no problem. i also picked up another linkage arm and it operates without the wipers on the car. once i put the wipers back on the car, it falls off. im thinking that the nylon in the linkages are getting aged and dont like being taken apart. when i took this apart at the junk yard it came apart hard, really was on there good. now go put it on my car and it doesnt fit that tight. i think those nylon inserts are getting old. any ideas besides buying a brand new part on ebay for $100?

Is it the wiper blades or the wiper arms? - BC

I don't think you can replace just the rubber. Rockauto has the part for around $100.
