Installation Notes and Tips

Verify rear to frame placement before installation and confirm the vehicle is a 1997-1999 INFINITI Q45 without Touring Suspension or a 2000-2001 INFINITI Q45. Inspect the stabilizer bar and mounting surfaces for wear, corrosion, or damage before installing the new bushings. Match the bushing dimensions to the original part to confirm proper seating and alignment.
