Jack up the axle and take the wheel off. With the spring is compressed, you can remove the shock absorber, if the spring needs to remove only, it is enough to let go one end of the shock absorber. To remove the spring, remove the top and bottom attachments while it is under compression, and then remove the compression by jacking up the body and, if necessary, letting down the axle until the spring and its spacers can be removed. Refitting is a reversal of unmaking.
