Front Left Steering Knuckle, Wheel Hub, and Bearing Assembly

Preassembled front-left steering knuckle kit for select Ford Escape, Mazda Tribute, and Mercury Mariner applications. The source lists the knuckle, bearing, hub, backing plate, and axle nut among the included components.

Critical fitment warning: Front-left/driver-side position only. The source does not specify FWD/AWD or 4WD restrictions, ABS configuration, engine, transmission, brake package, wheel size, production-date breakpoints, spline count, or connector details. Confirm the VIN, drivetrain, ABS and brake configuration, original knuckle shape, strut and ball-joint mounting points, tie-rod location, hub spline, and reference numbers before ordering.

Vehicle Compatibility

• 2001–2012 Ford Escape — front left
• 2001–2011 Mazda Tribute — front left
• 2007–2011 Mercury Mariner — front left

Fitment for the front-right side is not confirmed. Drivetrain, ABS, engine, transmission, brake, and production-date restrictions are not provided by the source.

Package Contents

• 1 front-left steering knuckle
• 1 wheel bearing
• 1 wheel hub
• 1 backing plate
• 1 axle nut
• Items described by the source as “Front Brake Shoes”
• Items described by the source as “Front Brake Hardware”

Package-content note: The source uses the term “Front Brake Shoes,” which may conflict with the vehicle’s actual front brake design or may be a catalog wording error. The source does not provide enough detail to reinterpret these items as brake pads. Inspect the product images and confirm the exact brake components and hardware before ordering. An ABS sensor or lead, wheel studs, ball joint, tie-rod end, strut bolts, brake caliper, and brake rotor are not explicitly confirmed.

Installation Notes

Steering, suspension, wheel-bearing, and brake work is safety-critical; professional installation and alignment are strongly recommended. Compare the complete assembly with the original before dismantling the vehicle. Inspect the CV axle, ball joint, tie-rod end, strut, brake components, ABS wiring, and mounting fasteners. Follow the vehicle manufacturer’s procedures and torque specifications, including the axle nut, strut-to-knuckle fasteners, ball-joint connection, tie-rod connection, caliper bracket, and wheel fasteners. Never use an impact tool for final bearing or axle-nut torque. After installation, verify smooth rotation, correct brake operation, secure ABS routing, no warning lights or abnormal play, and complete a four-wheel alignment before normal road use.

Frequently Asked Questions

Which side does this fit?
This assembly is specified for the front-left/driver side only.

Does it fit both FWD and AWD/4WD models?
The source does not specify drivetrain coverage. Verify the VIN, original knuckle, hub spline, and complete mounting configuration.

Is the hub and bearing already part of the kit?
The source lists one steering knuckle, one bearing, and one hub, plus a backing plate and axle nut.

Are brake pads included?
The source says “Front Brake Shoes” and “Front Brake Hardware,” but does not provide enough detail to identify these items as brake pads. Confirm the actual contents from the product images before ordering.
