Steering Knuckle Assembly 43211-KK010 For TOYOTA Hilux Revo GUN125 GUN126 GUN135 Fortuner AN150 AN160 2015-2025 — OEM Genuine Right Front RH, 96mm Wheel Bearing Bore

The Steering Knuckle Assembly with OEM number 43211-KK010 is a verified TOYOTA Genuine right-hand (RH) front steering knuckle for Hilux Revo (8th generation) and Fortuner II platforms. This component is the structural hub carrier that connects the front wheel hub to the upper and lower suspension arms and the steering tie rod. It dictates the mounting position of the wheel bearing, brake caliper, and steering arm, directly influencing wheel alignment geometry, steering response, and load-bearing integrity on these body-on-frame vehicles.

The 43211-KK010 is cataloged by TOYOTA as "KNUCKLE, STEERING, RH" (Code: 43211) and is the right-side counterpart to 43212-KK010 (LH). It is a cast steel component with a 96 mm wheel bearing bore, designed for the heavier duty-cycle demands of the Hilux Revo and Fortuner. This knuckle is a genuine OEM part, not an aftermarket casting, and is the correct replacement when the original knuckle is bent from impact, cracked at the strut or ball joint mounts, or has suffered bearing bore wear beyond service limits.

• OEM Genuine Status Verified: 43211-KK010 is confirmed as a TOYOTA Genuine OEM part across PartSouq, Amayama, eBay (Genuine Toyota listing), and multiple authorized Toyota parts catalogs.
• Position Verified: Front Axle, Right (RH) — confirmed by METZGER (Einbauposition: Vorderachse rechts), Euro4x4parts ("Right side"), and Yiparts ("Front Axle, Right").
• Paired Counterpart Verified: 43212-KK010 (LH) is the matched left-side knuckle, confirmed across PartSouq and Amayama catalog data.
• Wheel Bearing Bore Verified: 96 mm — confirmed by METZGER technical data ("fur Radlagerdurchmesser [mm]: 96") for the 43211-KK010 application.
• Material Verified: Cast steel / steel — confirmed by OEM parts descriptions ("robust cast piece") and aftermarket listing ("Body Material: Steel").
• Vehicle Coverage Verified: Confirmed for Hilux Revo (GUN125, GUN126, GUN135, TGN126, etc.) and Fortuner II (AN150, AN160) from 2015 onward, with catalog coverage extending to 2025.
• Aftermarket Cross-Reference Lead: METZGER 58183002 is confirmed as an aftermarket steering knuckle reference corresponding to OE TOYOTA 43211-KK010, with paired article number 58182901 (LH).

• Visible crack or deformation at the strut mount, ball joint taper, or tie rod arm: Impact damage (curb strike, pothole, accident) is the leading cause of knuckle replacement. A bent knuckle cannot be safely straightened.
• Wheel bearing bore wear or fretting: If the bearing race spins in the knuckle bore, the knuckle must be replaced — bearing replacement alone will not restore a worn bore.
• Inability to achieve correct wheel alignment: A bent knuckle prevents camber, caster, or toe from reaching specification, causing persistent tire wear and steering pull.
• Abnormal tire wear (cupping, shoulder wear): Geometry deviation from a damaged knuckle accelerates tire wear and reduces steering stability.
• Clunking or looseness at the front corner: A cracked knuckle or elongated ball joint taper can produce noise and unsafe play under load.
• Brake caliper misalignment: A bent knuckle can offset the caliper bracket, causing uneven pad wear or brake drag.

• KK010 vs. KK030 is the critical fitment boundary: PartSouq catalog data shows 43211-KK010 for GUN125/126/13# and 43211-KK030 for GUN11#/120/121/122/TGN11#/120/121. These are different castings for different Hilux Revo sub-variants. Provide the VIN or a photo of the original knuckle casting number before ordering.
• 2WD vs. 4WD: The confirmed applications are predominantly 4x4 / 4WD platforms (Euro4x4parts lists the 43211-KK010 equivalent for the GUN125 4x4 diesel). 2WD variants may use a different knuckle — confirm the drivetrain configuration.
• Wheel bearing replacement is mandatory with knuckle replacement: Industry guidance for this platform explicitly states that the wheel bearing must be replaced when installing a new steering knuckle. Reusing an old bearing in a new knuckle can lead to premature bearing failure and may void warranty.
• Genuine vs. aftermarket: This listing is positioned as Genuine TOYOTA OEM. If an aftermarket alternative is acceptable, METZGER 58183002 is a documented cross-reference, but confirm the buyer's requirement for OEM authenticity.

1. 1Confirm the correct variant first: Before removing the original knuckle, verify that the replacement is 43211-KK010, not 43211-KK030. Compare the casting number on the original unit.
2. 2Safety first: Park on level ground, engage parking brake, chock rear wheels. Loosen the front axle nut before raising the vehicle. Support the front corner securely on jack stands.
3. 3Remove the brake caliper and rotor: Support the caliper to avoid stressing the brake hose. Remove the rotor.
4. 4Remove the wheel bearing / hub: Press or pull the hub/bearing assembly from the knuckle. A new wheel bearing must be installed with the new knuckle — do not reuse the old bearing.
5. 5Disconnect the steering and suspension joints: Separate the tie rod end, upper ball joint, and lower ball joint from the knuckle using a proper separator. Do not hammer on the knuckle arms — cast steel can crack.
6. 6Remove the knuckle: Unbolt the strut/shock mount and any remaining fasteners. Extract the knuckle.
7. 7Transfer components: If any brackets, dust shields, or ABS sensor mounts are specific to the original knuckle, transfer them to the new unit.
8. 8Install the new knuckle: Position the 43211-KK010 knuckle, insert the strut mount bolts and ball joint studs. Torque all fasteners to the workshop manual specification — ball joint nuts and strut bolts are torque-critical.
9. 9Install a new wheel bearing and hub: Press the new bearing into the 96 mm bore and install the hub. Torque the axle nut to specification.
10. 10Reconnect brakes and steering: Reinstall the rotor and caliper. Reconnect the tie rod end. Check for any binding or interference through the full steering range.
11. 11Professional wheel alignment: Mandatory after knuckle replacement. Camber, caster, and toe must be reset to specification.
12. 12Road test: Test drive at low speed, listening for abnormal noise and checking for steering pull or vibration before returning the vehicle to service.

• Inspect the knuckle area at every suspension or brake service — look for cracks, impact marks, or bearing bore wear.
• Replace the wheel bearing whenever the knuckle is replaced — this is a platform-specific requirement for the Hilux Revo / Fortuner knuckle.
• Check wheel alignment after any impact event (curb strike, pothole, accident) — a bent knuckle may not be visually obvious.
• Do not attempt to straighten a bent knuckle — cast steel knuckles are not designed for cold or hot straightening and may crack.
