Thanks I saw where to grease. As soon as I can borrow my buddys grease gun this weekend im going to try it. I notice it seems like it does it when it is under acceleration. I shift to neutral and it goes away.
My brakes have about 10k mi on them. I had someone listen to it while it was rolling and it's coming from the back. I'll check my u joints tomorrow. If they are factory do they have grease certs?
I have a 99 super charged 4 Runner. It has started making a metal? like squeaking noise that seems like it is coming form the drive train. It speeds up with speed. Im think I may check the rear diff fluid. Any help would be great thank you.
