Should I be greasing my suspension?, if yes where and how often?

 

A stock F150 really only has two grease fittings that i know of and they are located on the left inner tie road and right above... thats it. If your suspension is 'sqeaking' a bit then you need to determine where it is at. if its the front end. More than likely its your upper and lower ball joints. You can replace these with "greasable" ones. I would recomend MOOG parts. If your rear end is sqeaking... You can replace your leaf spring bushings with an aftermarket one that is greasable, however more than likely its the springs themselves that are sqeaking... Old trucks just sqeak...
