i put new shocks on all 4 wheels this weekend, and surprisingly it still has the original shocks on them....with 131,800 miles...wow. and rides much better now. well when installing i noticed that i have a 5th shock? between my front two wheels on the axle.....what is this for? and do i need to replace this aswell since im sure its original like the 4 shocks were....when i hit a pot hole or a large bump sometimes it darts hard to the right or left....could this be that middle shock? or stablilizer or whatever it is???? thanks for any help..
