R33 gtr
Hey guys, need your help with identifying some car parts on my r33 gtr. I am not a mechanic, whatever i have learnt over the years is self taught so it is safe to say that i dont know everything that is on a car. Anyways i was replacing the front right inner cv boot and also fitting new rotors and i came across a hose that i dont know about. First photo is from the outside and second one is from the inside where the drive shaft connects into the hub. Also whats that white silicone stuff on the surface in the second photo?
Secondly i tried taking taking this bolt out shown in the third photo, using a braker bar i am able to spin it but thats all it doing. It doesnt get loose and just spins which requires a lot of force. All help is appreciated.
Thanks all.
