Complete Front Suspension & Brake System Upgrade for 2003-2009 Toyota 4Runner SR5 4.0L

If you drive a 2003-2009 Toyota 4Runner SR5 with the 4.0L V6, the front end of your truck works hard every mile. The CV axles transfer power through every turn. The pads and rotors haul the full weight of the vehicle down from highway speed. These are wear parts, and they tend to reach the end of their service life around the same mileage.

Replacing them one at a time means two or three separate jobs, repeated labor, and parts that wear at different rates. This package fixes that with one matched set: front CV axles, brake pads, and rotors engineered specifically for the SR5 4.0L. View the complete package details on the product page.

What Comes in the Package

• Front CV axles: high-strength steel construction with precision CV joints designed for the 4Runner's 4WD system.
• Brake pads: premium friction material optimized for the 4.0L V6's braking requirements, compatible with Dot 3 & 4 brake fluid.
• Brake rotors: precision-machined to OEM specifications for heat dissipation and durability, with a 6-lug pattern and heat-treated construction.

The Short Version

Technical Specifications

Every figure below comes straight from the package listing. The 89 LB total weight is the tell here — these are substantial steel components, not lightweight substitutes.

Wear Symptoms and Replacement Intervals

Each component in this package fails in a predictable way. Learn the symptoms now and you can schedule the job on your terms instead of reacting to a breakdown.

The maintenance guidance behind this package is simple: inspect the brake system every 30,000 miles or whenever abnormal noises occur, and expect CV axle replacement between 60,000 and 100,000 miles depending on driving conditions. If your 4Runner is closing in on either number, one front-end refresh makes more sense than piecemeal repairs.

Why the Complete Package Beats Separate Parts

Four reasons owners go with the full set:

There is a durability angle too. The 4.0L V6 fitted to 2003-2014 4Runners is known for its longevity — the engine typically outlasts the suspension and brake hardware around it. Refreshing that hardware is what keeps a durable truck feeling tight and stopping straight.

The guidance behind this package puts it plainly: regular maintenance of front-end components is essential for 4WD system health and safety. A clicking axle on a trail run or a pulsating brake pedal on a downhill is the truck telling you the safety margin is shrinking.

Fitment and Installation

This package is designed specifically for 2003-2009 Toyota 4Runner SR5 models with the 4.0L V6 engine. It is not a universal kit. Check your trim badge and engine before you order, because other trims and engines use different components.

Every component is engineered to meet or exceed OEM specifications, so fitment and performance match what Toyota intended. The 89 LB total weight reflects the substantial construction quality across the axles, pads, and rotors.

For optimal performance and safety, professional installation or consultation with a qualified mechanic is recommended — especially for the brake system. The package includes everything needed for a complete front-end refresh, which makes it an ideal project for trucks approaching 60,000-100,000 miles or already showing wear.

Round Out the Rest of the Front End

CV axles, pads, and rotors are the core of the job, but a worn upper ball joint will undo good work fast. If the truck wanders on the highway or your tires show uneven wear, add these front upper control arms and ball joints for the Lexus GX470, GX460, and Toyota 4Runner SR5 to the same order and refresh the upper geometry while the wheels are already off.
