Yup, that's them, I changed mine, they appeared to be fine though. I don't remember the part number off hand, but it's listed all over the board, hell, might be in my build thread, I remember putting a bunch of part numbers on there lol

I didn't replace mine, but I do fear that mine has gone bad recently. I need to go in there and inspect them again.

Articles like this make me glad I joined. The Trailblazer is the first 4WD vehicle I've ever owned so I was a little apprehensive about front diff matters. Not so much now! Good info!
