BYD Destroyer 05 Half Shaft Assembly

The half shaft (drive shaft / CV axle) is a core component of the vehicle's drivetrain system. Installed between the transmission differential and the front wheel hub, it transmits power from the transmission to the wheels to drive the vehicle. The shaft is equipped with constant velocity joints (CV joints) at both ends, allowing continuous power delivery even during steering and suspension movement. The Destroyer 05 features a front-wheel drive (FWD) layout with left and right half axles.

According to vehicle specifications, the Destroyer 05 is equipped with the BYD472QC 1.5L engine with a total motor power of 145kW and total motor torque of 325N·m, featuring an E-CVT transmission and front-wheel drive layout . As a high-load transmission component, the half axle is long subjected to high torque impacts and road vibration, making it prone to CV joint wear noise, torn boot with grease leakage, and spline wear .

In daily use, the half shaft assembly is one of the more frequently replaced components in the drivetrain system. Typical failure symptoms include: "clicking" noise when turning, vibration during acceleration, and humming noise while driving . According to maintenance recommendations, half shafts typically require inspection and replacement after 60,000-80,000 km or 3-4 years of use .

Our product is strictly developed to original Destroyer 05 OE specifications, with OE number 15131117-00 (right front half shaft) and material code SA6H-2203020. Shaft length, spline tooth count, and CV joint specifications precisely match the original 1:1. Compatible with all 2022-2025 Destroyer 05 models (55KM/120KM range versions, Champion Edition, and Glory Edition), as well as platform-sharing models including Seal 05 DM-i and Song Pro New Energy DM-i .

The shaft is forged from high-strength alloy steel with quenching and tempering heat treatment, and the splines are precision-rolled for high torsional strength and long fatigue life. The constant velocity joints (CV joints) at both ends feature wear-resistant bearing steel with high-precision needle bearings and super-finished raceways for smooth articulation during steering – eliminating "clicking" noise.

According to drivetrain principles, the half shaft CV joints feature BJ-TJ type constant velocity joints with high transmission efficiency and low vibration noise . The boots are made of high-temperature EPDM rubber pre-filled with high-quality lithium extreme-pressure grease for long-lasting joint lubrication.

The CV joint boots are made of high-temperature and ozone-resistant EPDM rubber, passing high/low temperature cycle testing (-40°C to 120°C). Boot failure is the most common cause of CV joint failure – once cracked, contaminants enter and quickly damage the joint, causing "clicking" noise.

Our product features reinforced boots with stainless steel clamps for reliable sealing. According to repair standards, boots and grease must be replaced when replacing the CV axle. Experience shows that once a CV boot is damaged, the joint typically fails within 2-3 months due to contamination.

Installation Instructions

Tool Preparation:

• 32mm/36mm socket wrench (hub nut)

• 18mm/19mm socket wrench

• Ball joint separator

• Torque wrench

• Pry bar

• Transmission fluid (for top-up if needed)

Important Safety Note: Half shaft replacement involves drivetrain disassembly – professional technician recommended. Ensure vehicle is off and securely supported before operation.

Installation Steps:

1. Lift Vehicle: Raise front of vehicle using lift, remove front wheels

2. Remove Hub Nut: Pry off hub nut dust cover, remove hub nut with socket

3. Remove Lower Control Arm Ball Joint: Use ball joint separator to disconnect control arm ball joint from knuckle

4. Remove Tie Rod: Disconnect tie rod ball joint (if clearance needed)

5. Remove Half Axle: Pull knuckle outward, carefully pry the half axle from the transmission differential with a pry bar. Protect the oil seal

6. Remove Old Half Axle: Pull the outer end of the half axle from the hub bearing, remove old half axle

7. Clean Mounting Area: Clean dirt from transmission oil seal area, check seal condition

8. Install New Half Axle: Insert inner spline of new half axle into transmission differential – ensure spline fully engages (audible "click"); insert outer spline into wheel hub bearing

9. Install Knuckle and Ball Joint: Reinstall control arm ball joint and tie rod in reverse order

10. Tighten Hub Nut: Install hub nut, torque to specification (typically 150-200 N·m)

11. Install Wheel: Install wheel, lower vehicle

12. Road Test: Verify no noise and no vibration

【Professional Tips】

• Protect transmission oil seal during half axle removal – damage causes oil leaks

• Check transmission fluid level after half axle installation – top up if necessary

• Wheel alignment recommended after half axle replacement

• Recommended to replace both left and right axles as a pair for symmetric drivetrain performance
