944 WIPER LINKAGE ARM

[Jinxy]

Hi guys, I had the dreaded drivers side ( RHS ) wiper linkage arm that kept popping off of the ball joint, so purchased Brand new Porsche passenger side & drivers side linkage arms, my question is, can both these linkages be replaced without taking the motor off of the car ?, ive felt behind the motor where both arms connect together on the motor shaft, but cant see how they are held on the shaft, are they just a push fit as there doesn't seem to be a nut or a clip to hold them in place ? or is it just brute force to pull them off ?, any help greatly appreciated, cheers, Tony

Hi Tony, I did this job last year and ended up taking the motor out. The arm just pushes on the spherical ball joints but its quite difficult to get good leverage on the arm and I was worried about damaging something. Having said that taking the motor out is a bit of a pain because you have to remove the fan housing. The benefit is you get to clean out all of the crap that has accumulated behind everything. There is a (German) YouTube video showing this job. It took me a few hours, there is a post I put on here if you search for it. Cheers Mark

Cheers Mark, I did think they were just pushed on but couldn't quite tell just from feel & yes I saw the German YouTube video last night, I was hoping I wouldn't have to go to all that bother if I'm honest, but if there is no other way then I suppose it'll have to do. Its a job I can probably put off until the warmer weather as I have put a piece of plastic sheet over the cup & pushed it onto the ball joint & it seems to be holding at the moment, but I know its only a temporary fix. cheers, Tony

They are push on and can be done without moving the motor. A bit fiddly but do-able. If your driver side one has fallen off I will predict your new arm will fall off also, within 6-12 months, as the wear is mostly usually on the spindle and not the arm. I had this nonsense repeatedly, after my 2nd new arm insisted on falling off, only in the rain mind, perfect when its dry [] , I decided to drill through the spindle and arm and install a split pin. It has never fallen off again, and it never will.

Drill straight through down the way, through the spindle and finally through the cup on the arm. It doesn't need to be bang on straight, close enough will do, then install a split pin or such like, nut and bolt with washer, take your pick, but for me the split pin was easy and has been bullet proof.

The split pin solution is very cheap and will last indefinitely - both my old tubs have been fixed this way. However ....... I do carry a spare split pin in the glove box ......... just in case[] Zeusy.
