Various projects on the C30's rear suspension require the coil springs to be removed from the car. This may seem like a daunting task. The springs support the weight of the vehicle and thus are under high tension loads. The springs also determine the ride height of the vehicle. It's fairly common these days to install a set of lowering springs to improve the vehicle's look. This article applies to that job as well.

You'll need to use a spring compressor to relieve the tension. Then remove the spring from the car. In this article, I will be using an internal-style spring compressor to relieve the tension. Even then, you'll still need to disconnect the lower control arm bolt to allow the spring to be removed. There is a factory Volvo tool for compressing the spring fully. However it lists at well over $900 at the time of this writing.

Also keep in mind that this is a potentially dangerous job. The springs are under hundreds of pounds of force when installed and also when compressed. Read the spring compressor's instructions carefully before performing this job.

Begin the job by jacking up the rear of your C30 and support it on jack stands. Remove the rear wheels, the lower shock absorber mounting bolt and the rear sway bar end links. See our articles on Jacking up Your C30, Rear Shock Absorber Replacement and Rear Sway Bar Bushing Replacement for more information.

Shown here is the rear coil spring in place on the Volvo C30.

Shown here is the rear coil spring in place on the Volvo C30. Disconnect the sway bar end link (green arrow) and also the lower shock absorber mounting bolt (not visible). Refer to our articles on Rear Sway Bar Bushing Replacement and Rear Shock Absorber Replacement for more information.

Shown here is the hook end of the spring compressor fitted inside the coil spring.

Shown here is the hook end of the spring compressor fitted inside the coil spring. You'll want the arms of the compressor (green arrows) to slide up as high as possible on the coil spring.

Tighten the spring compressor until you are able to move the whole spring from side to side with no effort.

Tighten the spring compressor until you are able to move the whole spring from side to side with no effort. This means that all the tension has been removed and it is safe to disconnect the lower control arm.

Even with the spring compressed, I found it very difficult to remove the spring without also disconnecting the lower control arm as shown here.

Even with the spring compressed, I found it very difficult to remove the spring without also disconnecting the lower control arm as shown here. See our article on Rear Control Arm Replacement for more information. Once the control arm is separated, pull the coil spring out along with the rubber isolators (green arrows) at both ends.

When installing the springs, make sure that the top and bottom ends of the springs (green arrows) fit into the molded portion of the isolator (yellow arrow).
