Brand - Bilstein.

Couldn't figure out how to remove? It's best to have a shop manual or cd, but it's really extremely straightforward. A word of caution. If you are not much of a Do It Yourself Mechanic, then maybe better to pay to have it done.

That caution out of the way. You simply jack up the car at the rear spring pad with a floor jack. Insert a Jack Stand at an appropriate contact point under the car. Then use a bottle jack under the control arm to allow easy manipulation of it's height. Remove the plastic undershield under the control arm. Remove the trunk fender liners. The top of the shock bushings and nut will be revealed. Remove them. Remove the bolt at the bottom of the shock.

Now you will discover the difficulty of Gas Pressurized shocks. Some prying, swearing, and leveraging will be necessary to get them out and back in. You need some jacks, a few tools, and a torque wrench. If you don't have these things, then their cost may be more than you say by doing it yourself.
