I ordered the mazda 3 rear wiper - the actual arm itself (bp4k-67-421) - 34.95 and then the blade bp4m-67-330a - 15.46. (they originally told me everything together was 35 bucks but when I picked it up the bill was 55...)
anyway I came home and pulled the stocker off and went to put this new one on and noticed it has no splines!?!?! I dont really see how putting a smooth holed' arm onto a splined shaft is goign to grip anything (only frictition there is from the splines rubbing the smooth shaft and what friction the nut puts on the arm...and id rather not do this as I dont want the splines to get all messed up)
Are there supposed to be splines on this mazda arm? I thought there was and they were the same as the focus hence the reason this works out. If anyone can tell me if this is in fact the way it works or if I have the wrong part (or a bad part...??) please let me know!
Thanks in advance
