Should use assembly lube when putting together any parts that move.
Clean threads of everything and if inside threads are dirty run a tap thru them,
I personally put one drop of light oil on bolt threads which will need to be torqued to a specific value.
put it together once, Check and recheck steps,
If you're using a sealant, Use Hylomar blue or something of very good quality,
And not too much beer during assembly, Its for after!
Keep us posted!
