GMC Yukon 2012-2020 Suspension Control Arm Replacement Guide
Clunking noises over bumps in your Yukon are a classic sign that your control arms may need attention.
- A wheel alignment is mandatory after replacing a control arm to prevent tire damage and ensure safety.
- For balanced performance, it's best to replace control arms in pairs (left and right).
- Buying a complete assembly with a pre-installed ball joint and bushings is much easier than replacing individual components.
- Verify the correct part for your Yukon's specific year, as the 2012-2014 and 2015-2020 generations use different parts.
Is Your Yukon Making Noise? Understanding the Symptoms
The most common sign of a failing control arm is a distinct clunking or knocking sound, especially when driving over bumps, potholes, or during sharp turns. You might also feel this through the steering wheel. 🎬 Watch: See how these common control arm symptoms look and sound. Other major symptoms include:
- Steering Wheel Vibration: A constant vibration that changes with speed can point to worn bushings or a bad ball joint in the arm.
- Loose or Wandering Steering: If you feel like you're constantly making small corrections to keep your Yukon straight, it could be due to worn control arm bushings causing play in the suspension.
- Uneven Tire Wear: A bad control arm can throw off your wheel alignment, causing the inner or outer edges of your tires to wear down much faster than normal.
- Visible Damage: Look for cracked or torn rubber bushings where the arm meets the frame, or a torn rubber boot on the ball joint where it connects to the wheel knuckle.
Important Note for 2012-2020 Yukon Owners
This year range covers two different Yukon generations: the 2012-2014 (GMT900 platform) and the 2015-2020 (K2XX platform). Suspension parts are NOT interchangeable between these generations. Always verify the part fits your exact year before ordering.
Known Issues, Recalls, and Service Bulletins
While widespread issues are not constant, there have been specific recalls for the GMC Yukon within this period.
- 2016-2017 Recall (NHTSA 16V-256): GM issued a recall for some 2016-2017 Yukons due to front upper control arms with poor quality welds that could fail. This could cause a loss of steering control. Dealers were instructed to replace both front upper control arms.
- 2023 Recall (NHTSA N232415910): This recall affected certain 2023 models (outside the 2012-2020 range) for a rear suspension bolt that could fracture, but it highlights the importance of suspension component integrity.
- Clunking Noises (TSBs): GM has released several Technical Service Bulletins (TSBs) over the years for front-end clunking noises. While not always the control arm, they are a frequent cause alongside struts and sway bar links.
Choosing the Right Aftermarket Control Arm
You don't have to buy from the dealer. Aftermarket brands often provide excellent quality, and some even offer improvements over the original design, like greaseable ball joints for longer life. Here’s a breakdown of common brand tiers:
- Premium (OEM Quality & Better): Brands like ACDelco (the original GM parts supplier) and Moog (known for their "Problem Solver" line) are top choices. They are engineered for durability and often feature enhancements like improved bushings or grease fittings that the original parts may lack.
- Standard (Value-Oriented): Brands like Dorman, Mevotech, and Suspensia offer a great balance of quality and cost. They are designed to meet or exceed original specifications and are a solid choice for daily driving and standard use. Some forum users have had positive experiences with Dorman and Mevotech's higher-tier lines (like Mevotech Supreme).
- Lift & Off-Road (Specialty): Brands such as Skyjacker, Superlift, Tuff Country, and Zone Offroad are not standard replacements. These are specifically designed for Yukons that have been lifted, providing corrected suspension geometry for larger tires and increased height. Only choose these if your vehicle is modified.

Frequently Asked Questions
Do I need an alignment after replacing a control arm?
Yes, absolutely. Replacing a control arm will change your vehicle's alignment settings. Skipping the alignment will cause poor handling and rapid, uneven tire wear.
Should I replace control arms in pairs?
It is highly recommended. If one side has failed due to age and wear, the other side is likely not far behind. Replacing both the left and right arms at the same time ensures balanced handling and suspension performance.
What's the difference between upper and lower control arms?
Your Yukon's front suspension has both. The upper control arm connects to the top of the steering knuckle, and the lower control arm connects to the bottom. They work together to secure the wheel assembly to the frame. Both can wear out, but they are separate parts and are replaced individually.
🎬 Watch: Replacing both upper and lower arms and calculating the savings.Is this a good DIY job for a beginner?
Replacing a control arm is considered a moderate-difficulty job. It requires a good set of tools, including a torque wrench and ball joint separator (or a large hammer), and a safe way to lift and support the vehicle on jack stands. While possible for a determined DIYer, it can be challenging due to stuck bolts and the need to work with heavy suspension components.
