Chevrolet Avalanche (2002-2013) Suspension Control Arm Guide
Addressing the common clunks, wandering steering, and uneven tire wear on your Avalanche by choosing the right control arm assembly.
- For 2007-2013 models, use a magnet to check if your upper control arms are steel or aluminum before ordering; they are not interchangeable.
- Symptoms of failure include clunking noises, steering wander, and uneven tire wear.
- Replacing the entire control arm assembly is easier and safer than pressing individual bushings or ball joints.
- A professional wheel alignment is mandatory after replacement to prevent tire damage and ensure safety.
Is Your Avalanche Making Noise? Recognizing a Bad Control Arm
The control arms on the Chevrolet Avalanche are durable, but the bushings and ball joints will wear out over time. When they fail, the symptoms are hard to ignore and can compromise safety. Look out for these common signs:
- Clunking or Popping Noises: This is the most frequent complaint. You may hear a distinct clunk or pop from the front end when going over bumps, making sharp turns, or braking. This sound is typically caused by worn bushings or a loose ball joint allowing metal-on-metal contact.
- Wandering or Vague Steering: If you find yourself constantly making small corrections to keep the truck straight on the highway, a worn control arm could be the cause. The steering may feel loose, unresponsive, or pull to one side.
- Uneven Tire Wear: Worn control arm components prevent the suspension from holding the proper alignment. This can cause the inside or outside edges of your tires to wear down prematurely.
- Steering Wheel Vibration: A failing control arm can cause vibrations that you feel directly in the steering wheel, especially at higher speeds. This is often due to worn bushings that can no longer absorb road shocks effectively.
Generation & Material Differences
The 2002-2013 Avalanche spans two GM truck generations, the GMT800 (2002-2006) and GMT900 (2007-2013). While the function is the same, the parts can differ. Notably, some 2007-2013 models came with either cast iron (steel) or cast aluminum upper control arms. These parts are not interchangeable. Before ordering, use a magnet to confirm which type your truck has; a magnet will stick to steel but not to aluminum. This is the most common ordering mistake.
Choosing the Right Aftermarket Part for Your Avalanche
Not all aftermarket parts are created equal. For the Avalanche, brands fall into a few distinct tiers of quality and price. Replacing the entire control arm assembly, which includes new bushings and a new ball joint, is almost always easier and more cost-effective than pressing out and replacing individual components.
Brand Quality Tiers
Based on owner feedback and mechanic consensus, aftermarket brands for the Avalanche can be grouped as follows:
- Premium & Heavy-Duty (Moog, Mevotech TTX/Supreme, ACDelco Professional): These brands are often considered upgrades over the original parts. They may feature stronger materials, improved designs (like Moog's "problem-solver" parts), and serviceable (greasable) ball joints to extend their lifespan. ACDelco Professional/Gold series are generally seen as high-quality replacements, sometimes better than the original. Mevotech's Supreme and TTX lines are popular for their durability on trucks.
- Standard Replacement (Dorman, Suspensia, ACDelco Silver): These brands offer a balance of quality and affordability for daily driving. Dorman is known for wide availability and ease of installation, though some users report longevity may not match premium brands. Suspensia is a known manufacturer of OE and aftermarket chassis parts.
- Lift Kit & Off-Road (Skyjacker, Zone Offroad, JBA Offroad): If your Avalanche is lifted, you need control arms designed to correct suspension geometry. Brands like Skyjacker, Zone Offroad, and JBA Offroad specialize in parts for modified suspensions, often featuring stronger materials and designs that allow for greater wheel travel and proper alignment on lifted trucks. 🎬 Watch this installation of forged upper control arms for lifted trucks.

Frequently Asked Questions
Do I need to replace the upper and lower control arms at the same time?
Not necessarily. You only need to replace the part that has failed. However, if one is worn out, the others are likely of a similar age and condition. It's wise to inspect all control arms, ball joints, and bushings when you have the wheel off. Many owners choose to replace uppers and lowers together for peace of mind and to save on future labor and alignment costs.
Can I just replace the ball joint or bushings?
While it is technically possible, it is often not practical for a DIY repair. Removing and installing pressed-in bushings and ball joints requires a heavy-duty hydraulic press and specialized tools. Given the labor involved and the risk of damaging the arm, replacing the complete control arm assembly is the recommended, easier, and safer method for most people.
🎬 See how to replace upper control arms on a Chevy Avalanche.Are there any recalls for the 2002-2013 Avalanche suspension?
Searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any recalls specifically for front control arm failure on the 2002-2013 Chevrolet Avalanche. There was a recall for some 2011 models related to a rear axle cross pin, but this does not involve the control arms.
Is a wheel alignment really necessary after replacing a control arm?
Yes, absolutely. Replacing a control arm will always alter your vehicle's camber, caster, and toe alignment settings. Skipping the alignment will result in a crooked steering wheel, poor handling, and will quickly destroy your tires, costing you much more in the long run. Factor the cost of an alignment into your repair budget.
What is the difference between the 2002-2006 (GMT800) and 2007-2013 (GMT900) control arms?
The two generations use different suspension designs and the parts are not interchangeable. The 2007-2013 GMT900 models, in particular, may have either steel or aluminum upper control arms from the factory, which must be correctly identified before ordering a replacement. The earlier 2002-2006 GMT800 models typically use steel arms. Always verify your specific vehicle's configuration.
