SITRAK C7H HOWO T7H Rear suspension bracket bushing AZ16D444000084
Replacement Interval
1. A visual inspection of the chassis should be performed during routine maintenance intervals when the vehicle has covered 150,000–200,000 km or has been in service for 2–3 years.
2. Signs of physical damage: Immediate replacement is required if the bushing exhibits eccentric deformation, edge crushing or tearing, cracking or collapse, or if the central through-bolt is noticeably tilted to one side.
3. Abnormalities during road tests: A metallic clanking sound emanating from the rear of the cab-accompanied by a marked increase in lateral swaying-when the heavy-duty truck passes over speed bumps or rough roads, or during sudden braking.
4. Troubleshooting Related Failures
Rear suspension air springs/shock absorbers: If the rear air springs leak, the height sensor malfunctions, or the shock absorbers fail (losing damping), the weight of the cab will exert a direct, rigid impact on the bushing, causing the new bushing to be crushed again within tens of thousands of kilometers.
Stabilizer bar (or thrust rod) ball joints: Check the stabilizer bar for deformation and inspect the ball joint rubber boots for cracking.
