I have an IR thermometer that's great for pinpointing heat sources. Maybe have your mechanic check when you drive in. If you are a customer he should do it for free. Takes less than a minute and I don't know any mechanic that don't have the tool.
Sorry I didn't follow-up...it wasn't a fun job doing it on the ground without a proper lift. The brakes are not as bad as they said, getting the link out-of-the-way is pretty easy. Possibly, when the brakes were done previously...they reversed the bolt so you didn't have to drive it passed the shock.
The sucky thing is the 4 bolts for the bearing go through the back and they're recessed into the casting. This car is also from the "rust belt" so that didn't help either. :wallbash:
