I busted my turn signal stem today and, apparently, you can't get just the stem from dealerships anymore. They sell the stem and switch as a single unit for $144.
I ordered just the stem from JeepsAreUs. I have never used them before so we'll see how it goes. Roughly $36 including shipping.

I'll comment on the post when I billing hits the card, I get notification of shipment and receive the part.
