Rear Knuckle Bushing for 1999-2005 Hyundai Sonata & More - Dorman 540-145

Help keep a quiet, controlled feel at the rear axle with the Dorman suspension knuckle bushing 540-145, a direct-fit rear replacement for the listed applications. It fits many vehicles, among them the 1999-2005 Hyundai Sonata, 2001-2006 Kia Optima and 2002-2005 Hyundai XG350. This rear bushing cushions the connection at the suspension knuckle, isolating road vibration and helping locate the knuckle to support proper wheel alignment. A worn or cracked bushing can show up as clunking over bumps, a loose rear-end feel, or uneven tire wear — if a failed knuckle bushing is the cause, this replaces it.

Engineered and tested to drop in like the original on the listed applications:

• Direct replacement: precision-engineered to match the design and dimensions of the original component so it fits and performs like the factory part on the listed vehicles.
• Durable construction: built to strict standards from sturdy, safe materials.
• Weather-resistant: made to stand up to the elements.
• Rigorously tested: thorough quality-control checks for long service life.
