Subaru Subaru Impreza 2017-present Suspension Specifications

The 2017-Present Subaru Impreza suspension system is compatible with models equipped with either the 2.0L or 2.5L engines. It features MacPherson struts in the front and a double-wishbone setup in the rear. The system is designed for both sedan and hatchback variants. Compatibility with aftermarket parts depends on the specific brand and model, but most components are interchangeable within the same generation.

The Subaru Impreza suspension requires regular inspections every 12,000 miles or annually, whichever comes first. Key maintenance tasks include checking for worn-out bushings, inspecting struts and shocks for leaks, and ensuring proper alignment. Lubrication of suspension components should be performed every 30,000 miles. Replace worn parts promptly to avoid further damage and maintain optimal performance.

To install or replace suspension components, first, safely lift the vehicle and remove the wheels. For strut replacement, disconnect the sway bar link and brake line bracket, then remove the strut assembly. Install the new strut, ensuring proper torque specifications for all bolts. For rear suspension, remove the lower control arm bolts and replace the shocks or springs as needed. Always follow the manufacturer's torque settings and alignment procedures.

Common suspension issues include noise, uneven tire wear, and poor handling. Start by inspecting the struts and shocks for leaks or damage. Check the bushings and ball joints for wear. Ensure the tires are properly inflated and aligned. If the issue persists, perform a road test to identify specific symptoms and consult a professional mechanic for further diagnosis.

To optimize suspension performance, consider upgrading to high-performance shocks and springs for better handling. Ensure proper alignment and tire pressure for even wear and stability. Regularly inspect and replace worn components. Adding a rear sway bar can improve cornering. Always use OEM or high-quality aftermarket parts to maintain reliability and performance.
