Carrier Bearing

Can you better describe the rumble? Mine is making a kind of "chittering" sound under load when cold. It seems to mostly go away once warmed up. I haven't had time to crawl underneath, but it sounds like it is coming from under the center console area.

I crawled under mine last night. There is way too much play. I'll be installing my Vertex replacement soon.

New Vertex carrier installed. I also greased the bearing. Noise is totally gone. Took about an hour.
