Chrysler 300 (2012-2023) Suspension Control Arm Bushing Replacement Guide
Eliminate suspension clunks and restore your Chrysler 300's smooth, controlled ride by choosing the right replacement bushings.
- Worn bushings cause clunking noises, poor steering feel, and uneven tire wear.
- Replacing the entire control arm is often easier and more cost-effective for labor than pressing individual bushings.
- Choose polyurethane bushings (Whiteline, Nolathane) for performance handling, or premium rubber (Moog, Delphi, Mevotech) for an OEM-like ride.
- A wheel alignment is mandatory after replacing any control arm or bushing to prevent tire damage and ensure safety.
Is Your Chrysler 300 Making Noise Over Bumps?
🎬 Watch: Hear what these suspension clunks sound like while driving.If you're hearing clunking, popping, or squeaking noises from your suspension, especially when going over bumps or turning, there's a good chance your control arm bushings are worn out. These parts are designed to wear over time. The original rubber bushings can crack, tear, or become soft, leading to excessive movement in the suspension. This not only causes noise but can also affect steering feel and tire wear.
Known Issues & TSBs
There is a Technical Service Bulletin (TSB #02-008-24) for some 2023 Chrysler 300 models regarding a "knock or rattle noise when going over bumps" caused by under-cured front control arm bushings. The fix involves inspection and possible replacement of the lower control arm(s). Additionally, a recall (NHTSA 20V-657) was issued for a small number of 2020 models for front lower control arms that could fracture. While these are specific issues, bushing wear is a common maintenance item across all 2012-2023 model years.
Choosing the Right Aftermarket Bushing
When replacing your bushings, you have several options. The biggest decision is whether to replace just the bushing or the entire control arm assembly. Pressing old bushings out and new ones in requires special tools like a shop press 🎬 Watch: How to install new bushings without using a press., making it a more difficult job for a DIYer. Often, replacing the entire control arm is faster, easier, and ensures all related components (like the ball joint) are new.
Aftermarket Brand Tiers for Chrysler 300
Not all aftermarket brands are created equal. They generally fall into three categories:
- Performance (Polyurethane): Brands like Whiteline and Nolathane offer polyurethane bushings. These are much firmer than the stock rubber, providing a noticeable improvement in handling response and durability. The trade-off is a potential increase in noise, vibration, and harshness (NVH), and they may require periodic lubrication. These are a great choice for enthusiasts seeking better performance. Note that Whiteline and Nolathane are owned by the same parent company.
- Premium OE-Style Replacement: Brands like Moog, Delphi, and Mevotech are known for making quality, durable replacements that aim to meet or exceed original equipment (OEM) specifications. Moog's "Problem Solver" line and Mevotech's "Supreme" line often feature design improvements over the original part for longer life. Delphi is a well-regarded brand often used as an OEM supplier. These are the go-to choice for most owners who want to restore original ride quality and have a long-lasting repair.
- Value-Oriented: Brands like Dorman and Suspensia offer a budget-friendly solution. They provide a wide range of parts that get the job done. While they can be a good option for a quick fix or a vehicle with a lot of miles, their long-term durability may not match the premium brands.
Pro Tip: Check Drivetrain and Position
The Chrysler 300 was available in both Rear-Wheel Drive (RWD) and All-Wheel Drive (AWD). These systems use different control arms and bushings. Always verify that the part you are ordering fits your specific drivetrain. Also, be aware of the specific bushing location (e.g., front upper, front lower forward, front lower rearward), as they are not interchangeable.

| Repair Option | Estimated Cost |
|---|---|
| Aftermarket Bushing-Only (Parts) | $11 - $156 |
| Aftermarket Control Arm Assembly (Parts) | $50 - $250+ per arm |
| Shop Labor (Bushings Only) | $204 - $300 |
| Shop Labor (Full Control Arm) | $141 - $206 |
*Prices are estimates and can vary based on location, specific part, and vehicle configuration. Labor for bushing-only replacement is higher due to the need to press the bushings in and out.
Frequently Asked Questions
Should I replace just the bushing or the whole control arm?
For most DIY mechanics and even many shops, replacing the entire control arm is the preferred method. It's faster and doesn't require a hydraulic press. It also has the benefit of replacing the integrated ball joint at the same time, which is another common wear item.
What's the difference between rubber and polyurethane bushings?
Rubber bushings, like the ones from the factory, provide a softer, quieter ride by absorbing more vibration. Polyurethane bushings (from brands like Whiteline) are stiffer, which reduces suspension flex, improves handling precision, and generally lasts longer. However, this stiffness can transmit more road noise and vibration into the cabin.
Do I need a wheel alignment after replacing control arm bushings?
Yes, absolutely. Replacing control arms or bushings will affect your vehicle's alignment settings. You must get a professional wheel alignment after the repair is complete to ensure proper handling, prevent premature tire wear, and maintain safety.
Can I replace bushings on only one side?
It is highly recommended to replace suspension components in pairs (both driver and passenger sides). If the bushing on one side has failed, the other side has experienced the same amount of wear and is likely to fail soon. Replacing them in pairs ensures balanced handling and predictable performance.
