Good morning,
You have standard shocks on your truck, not struts. Struts are for cars and trucks with the coil spring and shock as one unit.
I would replace them if the truck bounces too much to give the ride stability.

I would see if the noise is still there after the replacement. A worn out shock could cause the noise as well.
