Ok, I'm slinging grease all over the place and I'm having a little trouble locating the source. I originally assumed that I lost an outer boot off of a rear axle but I just got the car back from the transmission shop and the axles checked out ok. I crawled under the car in the driveway and from my limited viewing angle the source appears to be a joint located where the red is in this FSM pic. I believe this is the toe cam adjuster but I don't see anything in the FSM about it being packed with grease. Anyone have experience with the rear hub assemblies that can offer some insight?
