U joints sound like it might me it. Everything else looks good. Anyway to visually check?

End of rear drivers side axle. It's all over my brakes and inside of wheel.

Thanks for responding guys. Anything helps. Happy thanksgiving!

 

Did you recently switch to synthetic? I have heard a lot about the thinner synthetics leaking and when changing back the leak stops.

 

It's been leaking since the factory diff fluid was in.

 

Well good news. I just greased up the trackbar and sway bar links and that took care of the front end clunk.

I'll have the dealer in monterey look into the coolant issue cause I didn't have a friendly experience with the dealer here. But after driving a lot this weekend it seems to be fine for now.

Only thing is the leak out of the rear driver side axle. I checked the diff level and it was still full so it's a slow leak. It has been leaking since before I changed the diff oil. When I changed it the original fluid was filled way over the plug and made a big mess. Looking into some threads here it seems to have happened to a few people where it was overfilled and caused a leak.
Is there a write up anywhere here that explains the process to replace the seal? Will I need to rent any special tools like a press? I'd like to take care of this myself and learn something.
