To replace front struts, safely lift the vehicle and remove the wheels. Disconnect the sway bar link and brake line bracket. Unbolt the strut assembly from the steering knuckle and remove it from the vehicle. Compress the spring using a spring compressor, then transfer components to the new strut. Reinstall in reverse order and perform an alignment.

Q4

What are common suspension issues in the 1998-2001 Kia Sephia?

Common issues include worn struts or shocks, leading to a bumpy ride, uneven tire wear, or poor handling. Noisy suspension may indicate worn bushings or ball joints. Misalignment can cause steering pull. Inspect components for damage or wear and replace as needed. Regular maintenance helps prevent these issues.

Q5

How can I optimize the suspension performance of my Kia Sephia?

Upgrade to high-performance shocks or struts for better handling. Use polyurethane bushings for durability and improved responsiveness. Ensure proper alignment and tire pressure.
