How long do shocks/springs last?

How many miles do they last?

My car is coming up to the 40k mark in miles and the handling seems different. The ride is not as smooth as it used to be, like it will bounce around more on bumps on the road, and the body seems to wiggle from side to side a bit. Could this be some other suspension issue?
 
I just drive form school/work and back, never autocrossed or raced, other than accellerating fast in a straight line. I don't speed through turns or anything.

The car has had 2 other owners though, so I don't know how they treated it.
 
I also noticed another issue with my car.

The rear passenger side wheel sits out about 1 inch further than the one on the driver side. I checked out some other mustangs and it seems that the one on the driver side is correct, so for some reason the passenger side wheel is sticking out an inch too far, and it's not a wheel spacer, I checked that out.
 
The stockers are absolute garbage. Do not over spend on replacements. I got Gabriel SVT on all four wheels for less than $100 at AutoZone and easily installed them myself.

frame tolerances. look under the car and see how bad the frames are off from front to back.


as far as body roll, it comes with owning a mustang, and shocks/struts always play different roles in longativity. you could have a leaking one.
 
Ok, i've decided to try to replace the rear shocks on my own. This will be my first time doing anything like this to a car. The most I have done is basic engine tuneups.

I found this tutorial by searching on the forums. The author mentions he used Gabriel shocks and that they are pretty good for their price.
 
Stock GT shocks are not good for many miles at all, the most I'd go is 20k on the stockers. I'm with git-it-83, Koni shocks are the best you can get, Bilstiens are close but they don't adjust. Tokicos are pretty good and if you are on a buget and want an adjustable shock that is a good choice. I don't have any experience with any other shock but the ones I mentioned so I can't comment on those.
 
Do it right the first time and get Bilsteins. You never have to change them, and they'll never degrade due to age, usage or heat. Lifetime warranty included with Bilsteins, if you can wear them out, you'll get new ones.
 
Do not over spend. Remember, the people that bought Bilsteins and the like want to justify the excessive cost in their minds and recommend them to everyone else... Everyone loves what they bought...

You need to consider what you will use the car for and buy shocks that are appropriate.

This is kinda ignorant for you to say...Have you ever owened some bilsteins? Hahe you ever ridden in a BMW M3 with bilsteins? It compleatly changes the car, my $550.00 was more than worth every penny and i will "justify" the cost on every car I own for the rest of my life period, show me one bilstein owner who is unhappy and i will buy his bilsteins off him.
