2012 Goldwing CSC Viper Squeaking ??

[MrCement]

New to trike riding I have a 2012 Goldwing CSC Viper that has sat a lot of its life with 3,500 it has started to squeak when I go over bumps? Its only started the last 500 miles what do I need to address. I was hoping for some pretty detailed instructions on what I need to lubricate and what to do. It is hard to tell as I only hear it when I hit bumps.
Any Idea's I'm not real mechanical but I'm learning Thanks for your help.

There are grease fittings on the A arms, 2 on top and 2 on the bottom on each side. You'll need to get it in the air to reach the top ones.
