Front Suspension Components Overview
The 2017 Traverse uses a MacPherson strut front suspension design, which integrates the shock absorber and coil spring into a single unit. Key components include:
Strut Assemblies
The strut assembly is the main load-bearing component. It includes the strut (shock), coil spring, spring seat, and mount. The strut dampens road vibrations while the spring supports the vehicle’s weight. Worn struts cause excessive bounce, poor steering response, and uneven tire wear.
Control Arms and Ball Joints
The front lower control arm connects the wheel hub to the vehicle frame. It has two ball joints: an upper and a lower (though on some models only lower). The ball joint allows the control arm to pivot as the suspension moves. A worn ball joint can cause clunking noises and steering play.
Sway Bar Links
The sway bar (anti-roll bar) connects the left and right suspension via short links. These links reduce body roll during cornering. Broken links produce a rattling noise over bumps.
Tie Rod Ends
Tie rod ends connect the steering rack to the steering knuckle. They are essential for steering control. Loose or worn tie rod ends cause vague steering and uneven tire wear.
Wheel Bearings and Hubs
The wheel hub assembly contains the wheel bearing, which allows the wheel to spin freely. A failing bearing creates a humming or grinding noise that changes with speed.
Signs of Worn Front Suspension Parts
- Nose diving during braking indicates weak struts.
- Bouncing after hitting a bump suggests worn struts.
- Clunking or knocking when turning or going over speed bumps may point to worn ball joints or sway bar links.
- Steering wheel vibration at highway speeds often comes from worn tie rod ends or wheel bearings.
- Uneven tire wear (cupping or scalloping) is a classic sign of worn struts or ball joints.
- Excessive body roll during turns indicates weak sway bar links.
If you notice any of these symptoms, inspect the front suspension immediately.
Replacement Tips for 2017 Traverse Front Suspension Parts
Choose the Right Parts
OEM (Original Equipment Manufacturer) parts from ACDelco are direct replacements. Aftermarket brands like Moog, Monroe, and KYB offer quality alternatives at various price points. For struts, consider quick-strut assemblies that come pre-assembled with the spring and mount—they save time and eliminate the need for a spring compressor.
Strut Replacement
For the 2017 Traverse, the front strut assembly is straightforward to replace but requires lifting the vehicle and removing the wheel, brake caliper, and steering knuckle. Strut mounts and bearings should be replaced along with the strut. If you buy quick-struts, they include these parts.
- Monroe Quick-Strut (part #171440) is a popular choice for a complete assembly.
- KYB offers a quality strut (part #344253) but you may need to reuse or replace coil springs and mounts separately.
Control Arm Replacement
The lower control arm is often replaced as an assembly with the ball joint pre-installed. This reduces labor time. For the 2017 Traverse, the control arm has a hydraulic bushing that can leak; if worn, replace the arm. Moog (part #RK6456) and ACDelco (part #45G22113) are reliable options.
Sway Bar Links
Sway bar links are inexpensive and easy to replace. Moog (part #K750735) and ACDelco (part #45G21016) are good choices. Replace in pairs to maintain balance.
Tie Rod Ends
Inner and outer tie rod ends should be replaced if there is play. Moog (part #EV800140 for outer, #EV800161 for inner) and ACDelco (part #45G21420 for outer) are common replacements.
Wheel Bearings
Wheel hub assemblies for the 2017 Traverse are bolt-on units. Brands like Timken (part #HA590447) and ACDelco (part #45G22064) are recommended. Always replace wheel bearings with new axle nuts.
Buying Considerations and Compatibility
The 2017 Traverse front suspension parts are generally the same across trim levels (LS, LT, Premier). However, models with the towing package or heavy-duty cooling may have slightly different strut ratings. Check your VIN or confirm with a parts specialist. All-wheel drive (AWD) models use the same front suspension as front-wheel drive (FWD) for the 2017 Traverse.
- Struts: Ensure the quick-strut fits your specific model; some aftermarket struts have adjustable ride height? (Usually not on this model).
- Control arms: Verify if your vehicle has the hydraulic bushing (most do).
- Sway bar links: The length may vary slightly; measure or use OEM part numbers.
- Tie rod ends: Check if you need inner or outer; typically both are replaced in pairs.
Final Recommendation
For most 2017 Traverse owners, replacing worn front suspension parts with high-quality aftermarket components offers a good balance of cost and durability. If you are handy with tools, doing the work yourself can save hundreds of dollars. However, proper alignment after replacing struts, control arms, or tie rod ends is essential—take the vehicle to a shop for alignment.
As a practical recommendation: start with replacing struts and sway bar links if you have bouncing or nose diving. If you hear clunking on rough roads, check control arm ball joints and sway bar links first. Replace parts in pairs (both front struts, both lower control arms) to maintain symmetry and avoid premature wear. For the best value, use Moog or Monroe struts and Moog suspension components. If you prefer OEM, stick with ACDelco.
Regular inspection of front suspension parts every 50,000 miles will help catch wear early. Keeping your 2017 Traverse's front suspension in good shape ensures a safe, comfortable ride and extends tire life.
