Long time ghost first time posting. I have an 07 fourwinns factory trailer and I noticed the driver side wheel was leaking. There is a puddle of some sort of thin lube and the same lube leaking from the center hub. I know nothing about trailers and any help on how to fix it or what it is would be great.
