My rear sags a little. Should I replace all the springs or just the rear left springs? I have a tool box metal diamond plate type. Are these tool boxes heavy enough to cause this sag? (I doubt it just though I would ask) I did the "agressive push down test" to see how many times the truck bounces and it bounces two and a half times. Should I also replace all the shocks? I figure it makes to do every thing at once. From seaching posts it sounds like replacing the shocks is easy but how hard is it to replace the rear leaf springs?

 

Oh yah. Forgot to mention my 2wd pick up has 110 k miles on it and I think it is due for new shocks. As for the brand I am going to install, the ones X-AWDRIVER suggested sounds good since it is a 2wd onroad pickup truck but I plan on doing some hauling and towing so I might go with more heavy duty shocks and rear spring. I need to research this.
