Front Axle Steering Knuckle 8-97261545-2 8972615452 For ISUZU 700P ELF NKR81E 4HF1 — Right-Hand (RH), Hydraulic Brake Type, OEM-Spec Replacement

The Front Axle Steering Knuckle with OEM references 8-97261545-2 / 8972615452 is a verified structural suspension and steering component for the ISUZU 700P light truck and related ELF / NKR81E chassis equipped with the 4HF1 (4.3L) and 4HK1 (5.2L) diesel engines. This knuckle is the right-hand (RH) hub carrier that connects the front wheel hub to the upper and lower control arms and the steering tie rod, dictating wheel alignment geometry, steering response, and load-bearing integrity on the front axle.

The knuckle is specifically designated for hydraulic brake type applications — Persian-market ISUZU parts catalogs explicitly describe the right-hand variant as "بند انگشت فرمان راست (نوع ترمز هیدرولیک)" (right steering knuckle, hydraulic brake type) for the ISUZU 700P. The unit is a cast or forged steel structural component, and the official ISUZU parts description is "KNUCKLE; FRT AX" (Front Axle Knuckle). It is supplied as an OEM-specification aftermarket replacement, with the primary reference confirmed across ISUZU ELF/NKR81E parts diagrams and Russian-market steering knuckle catalogs.

• Position Verified (RH): Right-Hand — confirmed by Russian steering knuckle specialist ZEVS Parts listing 8972615452 under "Steering knuckle (trunnion) ISUZU ELF NPR 1999–2002 / ISUZU ELF NQR 1999–2002 правый" (right side).
• Brake Type Verified: Hydraulic brake type — confirmed by Persian-market ISUZU 700P catalog describing the right-hand knuckle as "نوع ترمز هیدرولیک" (hydraulic brake type) for OE 8-97261549-0 (a related RH reference).
• OEM Description Verified: "KNUCKLE; FRT AX" — confirmed by FinditParts official ISUZU parts listing for the related reference 8-97261-549-2.
• Vehicle & Engine Coverage Verified: ISUZU ELF NKR81E (KR-NKR81E-5JXYC) with 4HF1 4300cc (CNG) engine, April 2002 onward — confirmed by impex-jp ISUZU parts catalog. ISUZU 700P with 4HK1 / 4HF1 confirmed by Russian and Persian supplier catalogs.
• Cross-Reference Density Verified: 8-97261545-2, 8972615452, 8-97261549-0, 8972615490, 8-97261550-0, 8972615500, 8-97230-683-0, 8972306830, 8-97230-683-1, 8972306831 are consistently grouped as interchangeable/related references across ZEVS Parts, FinditParts, Ecer, and Persian ISUZU catalogs.

• 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.

• Right-Hand (RH) only: This is the right-hand knuckle. The left-hand counterpart uses 8-97261550-0 / 8972615500 (or 8-97261550-1). Do not interchange left and right — the steering arm angle and caliper mounting position differ.
• Hydraulic brake type: This knuckle is confirmed for hydraulic brake configurations. Air-brake variants may use a different knuckle specification. Confirm the vehicle's brake system type before ordering.
• 700P vs. ELF / NKR: The same knuckle reference family covers ISUZU 700P and ELF / NKR81E applications. However, confirm the exact chassis code and engine (4HF1 vs. 4HK1) against the VIN, especially for fleet applications with mixed models.
• Related RH references are not automatic substitutes: 8-97261549-0 and 8-97230-683-0 are grouped as related/alternative RH references in some catalogs, but physical comparison against the original knuckle is mandatory — production batches may have subtle differences in bearing bore or caliper mounting.

1. Confirm the required part first: Verify that the original knuckle is the right-hand (RH) unit and that the vehicle uses hydraulic brakes. Compare the steering arm angle and caliper mounting position to the replacement.
2. Safety first: Park on level ground, engage the parking brake, and chock the rear wheels. Loosen the front wheel lug nuts before raising the vehicle. Support the front corner securely on jack stands.
3. Remove the brake caliper and rotor: Support the caliper to avoid stressing the brake hose. Remove the rotor.
4. Remove the wheel bearing / hub: Press or pull the hub/bearing assembly from the knuckle. A new wheel bearing should be installed with the new knuckle — do not reuse the old bearing.
5. Disconnect 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 or forged steel can crack.
6. Remove the knuckle: Unbolt the knuckle from the suspension components and extract it.
7. Transfer components: If the original knuckle carries ABS sensor mounts, dust shields, or brackets, transfer them to the new unit.
8. Install the new knuckle: Position the 8-97261545-2 knuckle, insert the mounting bolts, and torque to the workshop manual specification.
9. Install a new wheel bearing and hub: Press the new bearing into the knuckle bore and install the hub. Torque the axle nut to specification.
10. Reconnect brakes and steering: Reinstall the rotor and caliper. Reconnect the tie rod end. Check for binding or interference through the full steering range.
11. Professional wheel alignment: Mandatory after knuckle replacement. Camber, caster, and toe must be reset to specification.
12. Road 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 — reusing an old bearing in a new knuckle can lead to premature failure.
• 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 — knuckles are not designed for cold or hot straightening and may crack.

• Standard packing: Heavy-duty carton or wooden crate with protective wrapping for a structural component; export pallet available for bulk orders.
• Package contents: 1 × Front Axle Steering Knuckle (Right-Hand). Wheel bearing, hub, ball joints, tie rod ends, and mounting hardware are not included unless explicitly stated — confirm exact package contents at inquiry.
