The Complete Guide to Ford Explorer Suspension Parts

The suspension system of a Ford Explorer is a complex network of components that work together to provide a smooth ride, stable handling, and proper tire wear. Whether you own a 5th generation Explorer or an older model, understanding the key Explorer suspension parts will help you diagnose issues, plan maintenance, and make informed upgrade decisions.

Key Components of the Ford Explorer Suspension

Struts and Shocks

Struts and shocks are the most recognizable suspension parts. On the Explorer, front struts combine a coil spring and shock absorber into a single unit, while the rear uses separate shock absorbers. These components dampen road impacts and control body roll. Common signs of worn struts include excessive bouncing, nose-diving during braking, and uneven tire wear.

Control Arms and Ball Joints

Upper and lower control arms connect the wheel hub to the vehicle's frame. They allow vertical wheel movement while maintaining alignment. Ball joints are the pivot points at the ends of control arms. Worn ball joints produce a clunking noise over bumps and can cause steering wander. On some Explorers, control arms come with non-replaceable ball joints, meaning you replace the entire arm.

Sway Bar and End Links

The sway bar (also called anti-roll bar) reduces body lean during turns. End links connect the sway bar to the control arms or strut. Broken end links cause a rattling sound over bumps and increased body roll. Replacing end links is a relatively inexpensive fix that can dramatically improve handling.

Coil Springs and Leaf Springs

Front suspension uses coil springs to support the vehicle's weight. Rear suspension on many Explorers employs either coil springs (independent rear suspension) or leaf springs (on older models). Sagging springs reduce ride height and lead to bottoming out. Over time, springs can fatigue or break.

Bushings

Rubber or polyurethane bushings are found at control arm pivots, sway bar mounts, and strut mounts. Worn bushings create sloppy handling, alignment issues, and squeaking noises. They are often overlooked but critical for precise suspension geometry.

Steering Components (Tie Rods and Idler Arm)

Although technically part of the steering system, tie rods and the idler arm affect suspension feel. Loose tie rods cause steering play and uneven tire wear. Inspect these when diagnosing front-end issues.

Signs Your Explorer Needs Suspension Work

• Clunking or knocking over bumps – often control arms, ball joints, or sway bar links.
• Excessive bounce after hitting a bump – worn shocks or struts.
• Vehicle pulls to one side – could be alignment, but also worn control arm bushings or ball joints.
• Uneven tire wear – scalloped edges indicate worn shocks; inner/outer wear suggests alignment issues.
• Steering wheel vibration – suspension components loose or worn.
• Bottoming out – weak springs or worn shocks.

How to Choose Replacement Explorer Suspension Parts

OEM vs. Aftermarket

• OEM parts are made by Ford or licensed suppliers. They match the original specifications and offer reliable performance. Best for routine replacements where you want factory feel.
• Aftermarket parts come in two tiers: economy and premium. Economy parts may save money but often have shorter life. Premium aftermarket brands like Bilstein, Monroe, or Moog offer upgraded durability or performance. Moog, for example, uses hardened steel and greasable joints on many parts.

Material and Construction

Look for control arms with forged or heavy-gauge stamped steel rather than thin stamped metal. Ball joints with nylon or metal-on-metal designs vary. For shocks, consider gas-charged twin-tube vs. monotube designs. Monotubes (like Bilstein 5100) are more responsive but cost more.

Ride Height and Lift Kits

If you plan to lift your Explorer, choose suspension parts designed for the lift height. Lift kits often include longer struts, shocks, and sometimes control arms to correct alignment angles. For leveling, spacer lifts are common but may require extended sway bar links.

Driving Conditions

• Daily driver: OEM or mid-range aftermarket like Monroe OESpectrum.
• Off-road or towing: Heavy-duty shocks (Bilstein 4600 or 5100) and polyurethane bushings.
• Performance handling: Lowering springs and adjustable shocks for a sporty feel.

Common Explorer Suspension Upgrades

Rear Shock Replacement

On many Explorers, rear shocks are straightforward to replace – two bolts each. Upgrading to gas-charged shocks reduces sway and improves ride quality when towing.

Front Strut Assembly

Using a complete loaded strut assembly (spring, strut, mount, boot) saves time and avoids the need for a spring compressor. Brands like Monroe and KYB offer these ready-to-install units.

Control Arm Replacement

On models where ball joints are non-replaceable, replacing the entire control arm is typical. Look for arms with pre-installed bushings to simplify installation.

Maintenance Tips to Extend Suspension Life

• Inspect boots and seals on ball joints and tie rods during oil changes. Torn boots let dirt in, accelerating wear.
• Check alignment annually or after replacing suspension parts.
• Greaseable joints should be lubed at every oil change if equipped with fittings.
• Avoid overloading the vehicle beyond its rated capacity to prevent spring sag and shock damage.

Final Recommendation

For most Ford Explorer owners, the best approach is to replace worn suspension parts with high-quality, brand-name components. If your Explorer has over 80,000 miles and you notice any symptoms, start with a thorough inspection of the front end – control arms, ball joints, and sway bar links are common failure points. For a balanced daily driver, Monroe OESpectrum struts and shocks paired with Moog steering and suspension parts offer reliable performance and good value. If you off-road or tow frequently, invest in Bilstein 5100 shocks and consider polyurethane bushings for better durability. Always replace parts in pairs (both front or both rear) to maintain even handling. A well-maintained suspension not only improves comfort but also safety and tire life.
