Front End Bouncing

replace the front shocks. check and see if you are getting any flat spot on you steer tires from tire bounce.

 

The more weight you put on the tires the more they will bounce. pop the shocks off and see how much resistance you get when you push them in. if there bad all you have are the springs. the tires will bounce on every little bump. and will be more pronounce as you add weight.

 

2 bolts. no need to jack the truck up.

 

Pushing the shock in is not a well know measure of whether a shock is bad or not, as depending on the manufacturer, Gabriel uses Hydraulic dampening vs. Monroe, which use Gas Pressure.

Unless you know the maintenance history of the truck or you are the owner, the best thing to do is just replace them as they are inexpensive enough at $45-55 dollars each and most people replace them whether they need to or not at 100k miles.
