Lubricating suspension components?

How often or do you guys lubricate your suspension components like lower control arm pivot points etc? To avoid squeaking and binding, rust?

 

I generally just try blast grit out with a hose before it gets too bad
I only lube my leaf springs if they start squeeking

 

I got some amsoil metal protector spray and sprays the lower control arm bushings, upper control arms, and strut mounts just to keep them in good shape and avoid any squeaks which I know these trucks are known for lol

 

better parts have zerk fittings.

stock parts are either worn or not.

 

Most aftermarket stuff suggest lube after first 500 miles and then every 5k miles after dependant on usage. I usually relube after every trip but my truck is a dedicated trail pig
