2009 Kia Rondo Right Rear Horizontal Bar Suspension Part: What You Need to Know

The 2009 Kia Rondo is a versatile compact minivan that offers a smooth ride when its suspension components are in good condition. One critical but often overlooked part is the right rear horizontal bar—also referred to as a rear lateral link or track bar. This component connects the rear axle to the vehicle body on the right side, controlling side-to-side movement and maintaining wheel alignment. If you're experiencing rear-end sway, uneven tire wear, or a clunking noise from the right rear, the horizontal bar may be worn or damaged. This article explains what this part does, how to identify it, common failure symptoms, and how to choose a replacement.

Understanding the Right Rear Horizontal Bar

The rear suspension of the 2009 Kia Rondo uses a multi-link setup. The horizontal bar (also called a lateral link or track bar) is a metal arm that runs laterally across the rear axle. On the right rear side, it connects the axle housing to the frame or subframe. Its main job is to keep the rear axle centered under the vehicle during cornering and over bumps. Without it, the axle could shift sideways, causing poor handling and tire scrub. On the Rondo, this part is typically a stamped steel or cast iron piece with bushings at both ends.

Location and Identification

The right rear horizontal bar is located under the vehicle, behind the right rear wheel, running from the axle tube toward the body. It is distinct from the trailing arms (which run longitudinally) and the sway bar links. To identify it visually, look for a horizontal metal bar with a bushing at each end—one bolted to the axle, the other to the chassis. The part is often coated in black paint or has a natural rusted look. If you need to purchase a replacement, you'll need the exact dimensions and bushing style. Common OEM part numbers for the 2009 Kia Rondo right rear horizontal bar include 55200-2E000 or 55210-2E000 (verify with your VIN).

Symptoms of a Faulty Right Rear Horizontal Bar

A worn or broken horizontal bar can cause several noticeable issues. Here are the most common signs:

Rear-End Sway or Wander

If the right rear horizontal bar has excessive play due to worn bushings or a bent bar, the rear axle can shift side to side. You may feel the rear of the vehicle "step out" during turns or at highway speeds. This is a safety concern.

Uneven Tire Wear

A misaligned rear axle due to a bad horizontal bar will cause the right rear tire to wear unevenly—often on the inner or outer edge. Check your tire tread regularly.

Clunking or Knocking Noises

When the bushings are worn, metal-to-metal contact can occur. You'll hear a clunk or knock from the right rear when going over bumps, accelerating, or braking.

Visible Damage or Rust

Inspect the bar for rust, cracks, or bends. If the bar is severely rusted, it may break. Also check the bushings for cracking or bulging.

Replacement Considerations

Replacing the right rear horizontal bar is a straightforward job for a DIY mechanic with basic tools, but proper alignment after replacement is critical. Here are key factors:

OEM vs Aftermarket

• OEM parts are made by Kia (often supplied by Hyundai Mobis). They have exact fit and durability but are usually more expensive.
• Aftermarket parts are available from brands like Moog, Duralast, or TRQ. They may offer upgraded bushings (like polyurethane) for better longevity. However, quality varies. Look for parts with a limited lifetime warranty.

Bushing Type

The stock bushings are rubber. They provide good noise isolation but wear out over time. Aftermarket options with polyurethane bushings are stiffer and last longer, but may transmit more road noise. Choose based on your comfort preference.

Complete Assembly vs Bushing Only

You can buy just the bushings and press them into the original bar, but if the bar is bent or rusted, a complete assembly is recommended. Many aftermarket suppliers sell the bar with bushings pre-installed.

Recommended Part Specifications

When searching for a replacement, ensure:

• Length: The right and left horizontal bars are often identical, but always confirm. The length for a 2009 Rondo is roughly 18-20 inches (measure yours).
• Bushing inner diameter: Typically 12-14 mm.
• Material: High-strength steel or cast iron. Avoid cheap aluminum replicas.
• Finish: Painted or coated to resist rust.

To avoid buying the wrong part, use your vehicle's VIN to cross-reference. Most auto parts websites allow you to filter by year, make, model, and engine.

Installation Tips

Replacing the horizontal bar requires:

1. Jack up the rear and support on jack stands.
2. Remove the wheel.
3. Unbolt the bar from the axle and chassis (may need penetrating oil if rusted).
4. Install the new bar with new bolts (often included).
5. Tighten bolts to manufacturer torque specs (typically 80-100 ft-lbs).
6. Lower the vehicle and re-torque bolts at ride height. This is important to prevent pre-loading the bushings.
7. After replacement, a wheel alignment is strongly recommended to set toe and camber.

Final Recommendation

If your 2009 Kia Rondo has more than 80,000 miles, consider inspecting the right rear horizontal bar and its bushings. For most drivers, an aftermarket complete assembly from a reputable brand like Moog (part number K-9614) is a good balance of cost and durability. Always replace in pairs? While not strictly required, replacing both rear horizontal bars simultaneously ensures even handling. Pair the replacement with new sway bar links and shock absorbers if those are also worn. After installation, get a professional alignment to protect your tires and ensure safe driving. With the right part and proper installation, your Rondo will handle like new again.
