Acura 51401-ST7-921 Front Coil Spring (Showa)

Inspect the shock absorber for damage and the coil spring for chips or cracks. Mount the assembly in a vise, marking the damper base's relationship to the spring. Install the spring compressor and relieve pressure from the damper base. Remove the damper cap, unscrew the self-locking nut, and lift the compressed spring. Slide the parts off the damper shaft, install the bump stop, dust cover, and plate onto the new damper unit. Extend the damper shaft and slide the components down. Place the coil spring onto the shock absorber body, install the mounting rubber, collar, base, seal, washer, and a new self-locking nut. Align the marks on the base and spring, tighten the nut, remove the spring compressor, install the damper cap and the assembly.

Use a jack to raise the vehicle and place it securely on jackstands.
