Yes, you generally need to remove the coil spring to replace the upper control arm bushings on a 1990 Dodge Ram van. The spring is in the way and prevents access to the bushing for removal and installation. There's not enough room to work around it. You'll likely need a spring compressor to safely remove and reinstall the coil spring.
