I don't think I'd need to make a thread for it, there may already be some. And you'd give me a big head if you said anyone looked forward to my posts.
If it has to be said, I don't plan to replace them until I replace the speakers in the doors, which is a back burner project for me. There is no immediate need to replace either component.
I learned to wrench the way you did doing this job. Trial and error, divide and conquer, and fix it right the first time, which also means using quality parts.
You plead the case of this being a pretty rough job, and my only opinion on your experience is that you've used a brand of parts that is known for its failure rates and that I would have researched which part to buy before pulling the trigger.
I applaud your effort in getting this job one, I know how intense delving inside a door can be if you've never done it before.
