Yep. If they don't look like they're sagging, if both sides are at the same ride height, and it doesn't sag too much when you've got a couple of people in the back seat, then you don't need to replace them. That being said, I've replaced the rear springs in nearly every 10-yrs+ volvo I've owned with stock springs and am always amazed at the difference. Handles better, little driveline noises disappear, and you can load up for camping!
