2011 DTS Base
I had been putting this off for a couple of months. The old pulley (pictured) still spun smoothly and there was no play in it at all. But once I opened it up you can see that there was hardly any grease under the seals. I added a pic of the seal so any sharp eyes out there could tell me if this was OEM or possibly replaced before I got the car. Regardless it's got a new one installed now and I feel a lot better.
