wiper motor removal
Posted: Fri Jan 15, 2010 3:49 pm
I finally got those SOB's removed. There was really nothing else keeping the threaded posts from coming out other than corrosion. I do a lot of work on Audi A8's and I see this type of galvanic corrosion on the suspension parts.
Once I realized that's what it was, I drilled a hole between the post and the windshield. You'll mess up the threads but nothing is threaded that low so it doesn't really matter.
Once I did that, I was able to rock it back and forth and finally get them out. If you have the same situation, I wouldn't waste a lot of time otherwise (I did). No amount of Penetrating oil of banging will free it up, it's mechanically fused.
I'm going to clean up all three on the bench, one might be bad. THEN I can install my new motor covers which is how this all started.
