Your taurus has struts. The strut is really just a shock absorber in a special housing with a big dish that mounts the bottom of the suspension spring to the shock absorber body.
I had all 4 replaced on my 1991 Taurus at about 110k miles, for about $400 at Midas, which was about the cheapest place around after extensive price checks. They put on Monroes with lifetime warranty, which means you save the $40 for the strut, but not the labor to replace it next time. The price is about $40 for the strut and $50-60 labor per strut.
If you have rear struts done, I stongly suggest an extra $20 or 30 per rear strut to replace the upper mount plate (not the real part name, but it's function - a plastic spacer about 1-inch thick). Midas didn't replace it and it ended up costing me about $60 installation per side to replace both about 10k after the struts were replaced because the top of the rear struts were rattling badly shortly after replacing the struts.
You will need to get the car aligned after replacing the struts, which the shop that does the replacement can usually do.
