Product Description

AZ9925528070 Left Rear Axle Equalizer Beam Assembly is installed in the rear axle suspension system of SINOTRUK heavy-duty trucks. The equalizer beam balances axle load distribution between dual rear axles, reduces chassis vibration, and improves driving stability during heavy-load transport and rough-road operation.

Bushing wear, beam deformation, welding cracks, overload fatigue, or lubrication failure may cause abnormal chassis vibration, uneven suspension height, tire wear, unstable steering, and rear suspension noise.

This suspension component is widely used in export fleet maintenance, mining truck overhaul, engineering vehicle repair, and commercial truck chassis aftermarket service.

Product Overview

This left rear axle equalizer beam assembly is commonly used on SINOTRUK HOWO T7H, HOWO T5G, SITRAK, STEYR, and Golden Prince heavy truck suspension platforms equipped with dual rear axle heavy-duty balance suspension systems.

Common Field Failure Case

Case 1

Vehicle: HOWO T7H Tractor Truck
Mileage: 760,000 KM
Problem: Rear chassis vibration during heavy-load operation
Root Cause: Equalizer beam bushing wear caused unstable axle balance
Solution: Replaced AZ9925528070 left equalizer beam assembly
Loss / Benefit: Restored suspension stability and reduced tire wear

Case 2

Vehicle: HOWO STEYR Dump Truck
Mileage: 920,000 KM
Problem: Rear suspension height uneven on rough-road operation
Root Cause: Beam deformation caused axle load imbalance
Solution: Installed OE-standard equalizer beam assembly and renewed bushings
Loss / Benefit: Improved chassis balance and reduced suspension stress

Case 3

Vehicle: Export Fleet Procurement Project
Mileage: Fleet Service Application
Problem: Wrong left/right beam supplied
Root Cause: Suspension side mismatch during procurement
Solution: Verified OEM number and installation side before shipment
Loss / Benefit: Avoided installation failure and repeat export freight expense
