Once I can verify these problems (need more RCM's) I'll do one of my DIY's with extensive pics and write up on how to fix the RCM yerself for both problems.
If this all works out we will save big $$$ and a lot of headaches.
PM me an address if you want to take a look at my spare one.
Again seller stated it was working but I have not tried it.
