Wiper Blade Hits the Hood?

On My 94 530I the P/S wiper blade hits / rubs the hood when in use, waring down both the top of the wiper arm where it mounts on the car and the paint on the bottom of the hood where it rubs. I am planning / hoping to paint my car this fall and would love to know an easy fix. This seems to be a common problem as I have seen it on other e34's. The blade is pressed down on the shaft as far as it will go and the hood has no damage or dents in it.

The bushings are worn out and you have to remove the wiper tranny. It is a pain to do. I do have a good wiper tranny for 40 plus shipping. I am still trying to get to my garage to check for the tan handle.

My wiper blade hits the hood and collides with each other when I put it on the highest speed, is this caused by the wiper bushings and tranny as well?

That sounds like worn bushings and worn wiper arms. If they are hitting each other then they are either not tight or they are worn and they are able to wiggle around and the arms need to be replaced.

Replacing a wiper tranny is a less-than-joyful experience. I stopped the wiper-hood collision by taking a Dremel sanding drum to the wiper arm to grind down the metal area impacting the hood. You can touch up the wiper arm with some flat black paint if you like.

WOW! I'm a girl and I wouldn't do that.

If that's the only thing wrong with the linkage, why not?

When the bearings finally seized up in my wiper transmission, I had to dismantle the cowling to replace it -- no options, because the wipers wouldn't move. With my big paws it took the better part of a day. Get a quote on the job from a shop, and maybe you'll find that notching the wiper arm isn't such a bad idea for a relatively insignificant problem.

On another forum I used to frequent, they'd refer to solutions like this as a "kludge." Some people say that's based on the German klug -- translation, "clever."

I understand, the old "if its not broke don't fix it" of most cars, can be, "if it's not totally broke on your BMW, don't totally fix it" I had my A/C condenser go out on my 740IL and after you remove the, console, air bags, steering wheel, dashboard and on and on, you could get to it, a 18 hour job by the books! It is not just bimmers though, on my 66 GTO it took a total of 10 min. to change all 8 sparkplugs and the points, on my nephew's Cougar, you have to take the motor loose and move it to change 6 sparkplugs.

My wiper bearing has very little up and down play, but no side to side, I was thinking of putting a rubber stopper between the hood and cowl to hold the center of the hood up a few mm to keep it from touching when I paint it, thoughts?

If the stopper contacts painted surfaces, it could wear through the paint as road vibration causes it to shift slightly while you drive. Beyond that, I'd say it's worth a try.
