54584-2E000 BUSH-LOWER ARM FAQ

Can I replace just this bushing or the whole arm?

You can replace just the bushing using a hydraulic press, which is more cost-effective. However, if the control arm is bent or the ball joint is also bad, replacing the complete arm may be faster.

What causes this bushing to fail early?

Frequent driving on unpaved roads, harsh braking habits, and environmental exposure to oil or extreme heat are the primary causes of rubber degradation.

Questions and Answers

What is the role of this component?
It serves as the rear mounting point for the front lower control arm, controlling horizontal movement and dampening road harshness before it reaches the cabin.
Which vehicles utilize this specific part number?
This part is designed for the Hyundai Tucson (JM) and Kia Sportage (KM), generally for model years 2004 to 2010.
Why is it called the "Rear" bushing?
Each lower control arm has two bushings; the 54584-2E000 is the larger, rearward-facing bushing, which handles more load than the smaller front bushing.
Is a wheel alignment necessary after replacement?

Yes. Since this bushing dictates the position of the control arm, replacing it will shift your caster and toe settings, requiring a professional alignment to protect your tires.
