How do you change a rear coil spring on a 1998 Kia Sportage?

Jack up the rear of the vehical and support it on jack stands from the FRAME, not the axel. From here, there are two possible choices. If the old spring is broken, simply pull it out by hand, if it hasn't already fallen out. To install the new spring, either use spring compressors (typically used for struts) to compress the new spring down enough to fit between the axle and the frame, or remove the shock on the side you are working on, while supporting the axle with a jack. Once the shock is removed (it is only necessary to remove 1 end), lower the axle enough using the jack to allow the new spring to fit. Raise the axle in place, reinstall the shock, and lower the vehicle .
