was thinking about greasing the bearings on my 2020 hd 10 defender. it has 7,000 miles on it. lots of information in this thread. Sounds like you have to take a bunch of stuff apart to even get started. Is there any videos on YouTube or somewhere else on what to do because I haven't found one yet? and is this the right greasing tool i need in this thread? Any advice would be awesome! Or does it even need greased?
