Default signs your shocks are wearing out

my car feels extra bumpy lately. i have a set of f-sport shocks, have about 40k miles on them (bought them brand new). is that a sign they're on their way out? it's not leaking or anything.

Over time, all shocks will wear out. The only thing you can visually check the shocks for (while installed on the car) is whether they are leaking. Remove the wheel and pull the shock's protection boot up. Look for leaks around where the shock rod enters/exits the shock body.

If the shock is removed from the car, you can compress the shock rod fully into the shock body. If the rod stays into the body or is slow to extend back out, it is bad.

thanks, how long does a typical set of f-sport shocks last?

When your shocks gone bad you will notice that your car will ride much harsher than it used to. Your car will bounce alot over bumps and potholes. You can feel the wheel bouncing excessively because that shock lost its damping to calm the spring down. In some cases, sign of worn out shocks will include clunking noise and leaking oil. 40K is quite positive your shocks can go bad especially if you are using them with F-Sport springs. F-Sport springs are notorious at killing shocks because of stiffer and progressive sping rates.

Honestly, from my knowledge, not all shocks that don't "rebound" are blown. Koni shocks are low pressure shocks, so naturally they rebound slowly or don't at all. However, as a first step check for visual leaks. If you get a chance to uninstall the shocks, apply pressure on "compression," there should be a decent amount of resistance; if not then they are probably blown.

The old school method is the bounce test and I quote: "A "bounce test" is still a valid means of checking the dampening ability of shocks and struts. If the suspension continues to gyrate more than one or two times after rocking and releasing the bumper or body, your shocks or struts are showing their age and need to be replaced.

The easiest way to rock the vehicle is to stand on the door sills and jump up and down a few times to gain some momentum. It should stop rocking within one "up and down motion" after you stop.

Good luck!
