2002 Dodge Stratus RT Rear Suspension Parts: A Complete Guide

The 2002 Dodge Stratus RT is a sporty variant of the mid-size sedan, equipped with a stiffer suspension for improved handling. Over time, rear suspension components wear out, leading to clunks, poor ride quality, and alignment issues. This guide covers the essential rear suspension parts for the Stratus RT, how to identify worn components, and what to consider when replacing them.

Understanding the Rear Suspension of the 2002 Dodge Stratus RT

The 2002 Stratus uses a multi-link independent rear suspension. The RT model features upgraded springs and struts compared to the base models, giving it a firmer ride and better cornering. The system includes struts, control arms, trailing arms, a sway bar, coil springs, and numerous bushings. Each part plays a role in maintaining wheel geometry and absorbing road impacts.

Key Rear Suspension Components

Struts and Shock Absorbers

The rear struts on the Stratus RT are a combined spring and damper unit. They control vertical motion and keep the tire in contact with the road. Signs of failing struts include fluid leaks, excessive bouncing, and uneven tire wear. For the RT, consider performance-oriented struts that match the sporty character, such as KYB Gas-A-Just or Monroe OESpectrum. If you want to maintain the original ride height and handling, OEM replacements are also available.

Control Arms and Trailing Arms

The rear suspension uses upper and lower control arms, plus trailing arms to locate the wheel. Worn bushings in these arms cause clunking and vague handling. Polyurethane bushings offer longer life than rubber but can increase road noise. Trailing arm bushings are especially prone to wear on the Stratus. Moog and Mevotech supply high-quality replacement arms with pre-installed bushings.

Sway Bar and End Links

The rear sway bar reduces body roll during cornering. The end links connect the bar to the control arms. Worn end links produce a rattling noise over bumps. Replacement is inexpensive and should be done in pairs. Aftermarket sway bars are thicker for sharper handling, but OEM bar diameter is sufficient for most drivers.

Coil Springs

Coil springs support the vehicle weight and absorb impacts. Sagging springs lower the rear and cause bottoming out. The RT has stiffer springs than base models. If you are replacing struts, it is wise to replace springs at the same time, especially if the car has high mileage. Stock height springs are readily available; lowering springs (e.g., Eibach) can improve looks but reduce ground clearance and ride comfort.

Bushings and Ball Joints

Bushings are found in control arms, sway bar mounts, and the subframe. Hardened, cracked, or dry-rotted bushings allow excess movement. Ball joints in the rear are generally part of the control arm assembly; if the joint is loose, replace the entire arm. Polyurethane bushing kits are popular for enthusiasts but require more frequent lubrication.

Knuckles and Hubs

The rear knuckle connects the wheel bearing to the suspension arms and strut. Hub bearings can fail, causing grinding noises and play. Replacing the hub assembly typically involves removing the knuckle on the Stratus. Use quality bearings from Timken or Moog for longevity.

Signs That Your Rear Suspension Needs Attention

• Clunking or popping noises when going over bumps or turning.
• Excessive bouncing after hitting a dip, indicating weak struts.
• Uneven tire wear, especially cupping or scalloping on the inner or outer edges.
• Rear end sagging or one side sitting lower than the other.
• Poor handling such as wandering or body roll in corners.
• Vibration or shimmy from the rear at highway speeds.

OEM vs Aftermarket Parts: What to Consider

OEM (Original Equipment Manufacturer) parts from Mopar are identical to what came on the car. They ensure correct fitment and ride quality but are often more expensive. Aftermarket parts vary widely in quality and price. For the RT, consider brands that match the sporty intent:

• Struts: KYB (Excel-G or Gas-A-Just), Monroe (OESpectrum), Bilstein (B6 for performance).
• Control Arms: Moog (problem solver series), Mevotech (TTX series), Dorman (OE solutions).
• Springs: OEM replacement from Mopar, or aftermarket from Eibach, H&R, or Moog.
• Sway bar links: Moog, ACDelco, or Mevotech.
• Bushings: Energy Suspension or Prothane for polyurethane.

Avoid generic low-priced parts, as they may wear quickly and compromise safety. Check forums like Dodge Stratus enthusiast sites for common aftermarket parts that have worked well.

Tips for Replacing Rear Suspension Parts

• Safety first: Always support the vehicle with jack stands on the frame, not the suspension arms. Use a floor jack to assist with compressing the suspension.
• Alignment: After replacing any suspension component affecting wheel alignment, get a four-wheel alignment immediately. The Stratus rear camber and toe are adjustable; a shop will set them to factory specs.
• Torque specifications: Use a torque wrench for all bolts. Many rear suspension bolts should be tightened with the suspension under load (vehicle on the ground) to avoid preloading bushings.
• Replace in pairs: Always replace struts, springs, and control arms on both sides of the rear axle to maintain balanced handling.
• Penetrating fluid: Apply penetrating oil to bolts a day before working to ease removal, especially for rusted hardware.
• Special tools: A spring compressor is required to replace struts if you are separating the spring from the strut assembly. Many aftermarket quick-strut assemblies come pre-assembled, simplifying the job.
• Check related parts: While in the area, inspect parking brake cables, brake lines, and wheel bearings. Replace any worn items to avoid future issues.

Recommended Brands and Part Selection

For the 2002 Stratus RT, the following brands are trustworthy for rear suspension parts:

• Struts/Shocks: KYB Gas-A-Just (monotube) for a firm ride, Monroe OESpectrum for a balance of comfort and control.
• Control Arms: Moog Problem Solver with greasable ball joints and bushings.
• Sway Bar Links: Moog or ACDelco professional grade.
• Coil Springs: Moog CC-series for stock height, Eibach Pro-Kit for a mild drop (about 1.3 inches).
• Bushings: Energy Suspension hyper-flex for polyurethane.

For a direct fit without guesswork, OEM Mopar parts are available from Dodge dealers or online Mopar retailers. However, aftermarket equivalents often provide equal or better durability at a lower cost.

Final Recommendations

Focus on the components that cause the most common issues: struts, control arm bushings, and sway bar links. If your Stratus RT has over 100,000 miles, consider replacing all four struts and the rear springs. Pair these with new strut mounts and bump stops. Use a reputable aftermarket brand like KYB or Monroe for struts, and Moog or Mevotech for arms and links. Always replace bushings with quality units to avoid premature wear. After completing the work, schedule an alignment to protect your tires and ensure the car handles as intended. With proper parts and installation, your 2002 Stratus RT will ride and corner like new for years to come.
