ISUZU Wheel Hub Bolt 1-42333346-0 1423333460 for CXZ FVZ CVR — Rear Wheel High Strength OEM Standard

Opening:
The ISUZU Wheel Hub Bolt with OEM numbers 1-42333346-0 / 1423333460 is a heavy-duty replacement designed for ISUZU CXZ, FVZ, and CVR series trucks, compatible with 6WF1 diesel engines. This component is a critical safety part of the wheel attachment system — the Rear Wheel Hub Bolt — responsible for securely fixing the wheel to the hub, ensuring the wheel does not loosen during vehicle operation.

📌 Numbering Note: This product number is 1-42333346-0 / 1423333460. The same series also includes 1-42333345-0 / 1423333450. Model years: 2000–2020. Please verify the specific number based on actual vehicle configuration.

Working Principle:
The wheel hub bolt (wheel stud) is a critical connection component between the wheel and the hub, press-fitted and fixed into the hub flange. The wheel is mounted onto the wheel studs through the rim bolt holes, and lug nuts are tightened from the outside to securely fasten the wheel to the hub. During heavy-duty truck operation, this assembly withstands complex alternating loads (including vehicle weight, payload, acceleration/braking tangential forces, and cornering lateral forces). Its strength and quality directly determine the reliability of wheel attachment.

1. Number Confirmation: This product number is 1-42333346-0 / 1423333460. Same series also includes 1-42333345-0. Verify the specific number on the original part before ordering.
2. Strength Grade Confirmation: Heavy-duty truck wheel bolts typically require Grade 8.8 or higher. Confirm this product meets vehicle OEM specifications before installation.
3. Pair Replacement Recommended: When replacing hub bolts, it is recommended to replace lug nuts simultaneously to ensure proper thread fit and reliable clamping force.
4. Installation Torque: Refer to ISUZU factory workshop manual for lug nut torque specifications. Cross-tightening with a torque wrench is mandatory.
5. Post-Installation Re-torque: After installation, re-check and re-torque lug nuts after 50–100 km of driving.
6. Professional Installation: Hub bolts are critical wheel attachment safety components — professional installation is strongly recommended.

Hub bolts are critical wheel attachment safety components that directly affect vehicle driving safety. Professional installation with specialized tools (torque wrench) is strongly recommended. Torque to specification is mandatory after installation, and re-torque after driving is required.

Preparation:

• Confirm installation position (Rear Wheel) and part number (1-42333346-0)
• Prepare tools: Torque wrench, socket wrench, jack + safety stands
• Recommended to prepare new lug nuts

Removing Old Hub Bolts:

1. Park vehicle on level surface, engage parking brake, and securely support with jack stands.
2. Remove the wheel (tire).
3. Remove brake drum/rotor (if necessary) to access hub flange.
4. Press out old hub bolts from the hub flange using a special tool.

Installing New Hub Bolts (Installation Sequence):

1. Clean mounting holes: Thoroughly clean bolt mounting holes in the hub flange — ensure no oil, dirt, or debris.
2. Install new bolts: Insert new hub bolts into mounting holes from the inside of the hub flange.
3. Press into position: Use a special tool or press to press bolts into the flange — ensure bolt head fully seats against the flange.
4. Install wheel: Mount the wheel onto the hub — ensure rim bolt holes align with wheel studs.
5. Install lug nuts: Install lug nuts and hand-tighten in cross-pattern.
6. Final torque: Using a torque wrench, tighten lug nuts in cross-pattern to specification (refer to ISUZU factory workshop manual).

Post-Installation Checks (Mandatory):

1. Torque check: Confirm all lug nuts are torqued to specification.
2. Re-torque after driving: Re-check and re-torque lug nuts after 50–100 km of driving.
