Drive Half Axle Shaft Rear 8-98080678-2 8980806782 For ISUZU D-MAX Pickup Truck

The Drive Half Axle Shaft Rear (OEM Numbers: 8-98080678-2 / 8980806782) is a premium-quality, direct replacement driveline component designed specifically for ISUZU D-MAX pickup trucks. This rear axle half shaft — also known as a rear axle shaft, drive axle shaft, or half shaft — is a critical part of the rear axle assembly.

It connects the differential side gear to the rear wheel hub, transmitting engine torque to the rear wheels while allowing the suspension to move up and down. It is engineered to withstand the high torque loads, continuous rotation, and harsh conditions of both on-road and off-road driving.

Function: The rear drive half axle shaft transmits torque from the differential to the rear wheel hub, driving the wheels while allowing suspension movement in ISUZU D-MAX pickups.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function.
• High-Strength Forged Steel: Durable alloy steel withstands high torque loads and continuous rotation.
• Hardened Bearing Surface: Heat-treated and precision-ground shaft surface ensures smooth bearing operation and long service life.
• Precision Splines: Exact spline count and profile ensure proper engagement with the differential side gear.
• Accurate Hub Flange: Machined flange ensures proper wheel and brake component mounting.
• Restores Power Transmission: Eliminates loss of drive, vibration, and noise caused by a worn or broken half shaft.
• Direct Replacement: Matches OE shaft dimensions, spline count, and mounting configuration.
• Long Service Life: Engineered for pickup truck applications, including off-road and heavy-load use.
• Essential Driveline Component: Critical for reliable power delivery to the rear wheels.
• Cost-Effective Repair: Affordable replacement that prevents costly differential and wheel-end damage.

This rear half axle shaft is specifically designed for ISUZU D-MAX pickup trucks. Common applications include:

• ISUZU D-MAX (Pickup Truck) — various model years (verify with VIN)

• ISUZU 4JJ1 — 3.0L Inline-4 Turbo Diesel
• ISUZU 4JK1 — 2.5L Inline-4 Turbo Diesel
• Other D-MAX diesel engines (verify with VIN)

Professional mechanic or driveline specialist installation is strongly recommended:

1. Ensure vehicle is safely raised — Use appropriate jack stands or a lift to support the rear axle.
2. Disconnect battery — Always disconnect the negative terminal before working.
3. Drain differential oil — If required, drain the differential oil to prevent spillage.
4. Remove the rear wheel — Remove the wheel and tire assembly on the side being serviced.
5. Remove the brake components — Remove the brake drum or caliper and rotor as required to access the axle shaft.
6. Remove the axle shaft — Remove the retaining bolts or C-clips securing the axle shaft; use a slide hammer or pry bar to withdraw the shaft from the axle housing.
7. Inspect related components — Check the axle bearing, seal, differential side gear, and wheel hub for wear or damage; replace if necessary.
8. Clean mating surfaces — Remove dirt, oil, and debris from the axle shaft, housing, and hub mating surfaces.
9. Install the new axle shaft — Carefully insert the new half shaft into the axle housing; align the splines with the differential side gear.
10. Seat the shaft — Push the shaft fully into the differential until it seats; install the retaining bolt or C-clip.
11. Reinstall brake components — Reinstall the brake drum or caliper and rotor.
12. Reinstall the wheel — Install the wheel and torque lug nuts to specification.
13. Refill differential oil — Fill with the correct grade and quantity of differential lubricant.
14. Check for leaks — Inspect the axle seal area for oil leakage.
15. Road test — Test drive to verify proper operation, no abnormal noise, and no vibration.
