Admin note – An older tutorial I put together that was worth another mention. This seems to be a popular topic in my inbox over the last few weeks.
I’m going to start off by being 100% honest: rebuilding your doors isn’t easy.
I’ve read “the experience is best described by words not suitable for polite company.” However, YOU CAN DO IT! I called around the Bay Area before taking on the task myself. Most shops (that would actually take on such a job) wanted $800-$1,200.00, plus parts.
Rest assured, this is in fact a task you can handle. The biggest part of it all is taking your time. Deep breaths, and take each part step-by-step. I also recommend picking up a set of plastic stack-on organizer bins, as inside door components are small and can be easily lost.
In my opinion, good progress is about 6 hours per door. This includes breaking everything down, checking the regulators, re-greasing parts, installing inner and outer scrapers, and slowly getting everything back to its former German glory.
Before you jump into the task, you’re going to need the correct parts. (German parts!) We have it covered. Here’s a breakdown of what you need to complete the job. This is assuming your door regulators, window winder, vent windows and lift channels are in working order. I did have to replace my left lift channel because it was rusted out.
