I have a question. My rear end of my 94 Caddy Seville is sagging. I do notice my suspension pump engaging and I also notice it raising the rear of the car on start-up, but when I cross speed bumps and ride along bumpy highways my car bottoms out in the rear.

I was just wondering whether should I invest in rear struts or springs, or both.

My thought was the springs due to the car still sagging after the struts lift the car on start-up.
