Product Advantage

1. [Long life] Military grade alloy steel body+salt spray protection technology

Made by forging SAE 1045 high-strength alloy, the tensile strength reaches over 850MPa, which increases the service life by 200% compared to ordinary materials. The triple rust prevention process (zinc nickel coating+phosphating treatment+polymer sealing) has passed a 480 hour salt spray test, completely solving the problem of ball head corrosion and oil leakage. Specially designed for high load suspension systems, suitable for harsh road conditions, and eliminates frequent maintenance pain points caused by chassis noise.

2. [Precise Control] Hot forged precision bearings+0.1 ° steering deviation control

The embedded high carbon chromium steel bearings undergo vacuum heat treatment, with a friction coefficient below 0.08, ensuring zero delay in the response of the steering system. The CNC machining tolerance is controlled within ± 0.05mm, and the steering angle deviation is ≤ 0.1 ° to avoid the need for vehicle deviation correction. Tested to reduce steering wheel vibration by 40% and improve high-speed driving stability.

3. [Safety reinforcement] Impact energy absorbing structure+50000 fatigue test certification

Original hydraulic explosion-proof design: 3mm thick shell+internal buffer silicone layer, capable of absorbing instantaneous impact force of 15kN. Passed SAE J489 mechanical performance certification, 50000 dynamic fatigue tests without failure, eliminating the risk of ball head detachment accidents and providing the ultimate guarantee of driving safety for multi link suspension.

4. [Maintenance free design] PTFE self-lubricating joint+lifetime sealing technology

Inject DuPont PTFE composite grease into the joint cavity, suitable for a wide temperature range (-40 ℃~180 ℃), reducing friction loss by 90%. The laser welded sealed shell is equipped with a double-layer nitrile rubber dust cover, which has passed the IP6K9K dust and waterproof certification, achieving lifelong oil free maintenance and saving maintenance costs for the suspension system.

5. [Precise adaptation] 3D scanning of original factory data+vehicle model coverage rate of 98%

Based on laser 3D scanning OE part data development, the ball head taper/thread/installation hole position is 100% in line with the original factory specifications. The database covers over 2000 vehicle models and provides precise matching of original car replacement ball joints. Comes with installation positioning buckle to avoid inaccurate four-wheel alignment data.

Product Uses

Here are specific application scenarios of Chery Amulet:

1. Steering noise and stuttering repair

When a vehicle makes a "clunking" noise when turning at low speeds or when the steering wheel returns to normal and gets stuck, it is often due to the wear of the ball joint causing excessive steering clearance. This product's precision bearings can eliminate abnormal noise in the steering system and restore smooth steering wheel operation.

2. Eliminate the feeling of looseness in suspension

When driving on bumpy roads, does the chassis experience a "loose shaking sensation" or even abnormal tire wear? This is a suspension misalignment caused by the failure of the ball joint. Strengthening the hydraulic energy absorbing structure can tighten the suspension geometry, solve the problem of loose multi link suspension, and improve high-speed stability.

3. Frequent failure of four-wheel alignment

If the vehicle needs to repeat four-wheel alignment every six months, it is highly likely that the positioning parameters will drift due to the deformation of inferior ball joints. The CNC precision machining taper ensures a 100% fit with the original hanging hole position, avoiding repeated misalignment of positioning data.

4. Suspension reinforcement for off-road vehicles

In response to the high-intensity impact of hardcore off-road vehicles on unpaved roads, the triple dust-proof seal (IP6K9K) effectively blocks the intrusion of mud and sand. The military grade alloy steel body has a tensile strength of 850MPa, completely solving the early oil leakage problem of off-road ball joints.

5. Winter low temperature turns heavy

Is the steering wheel heavy in cold regions? The failure of low-temperature lubrication for ordinary ball joints is the main cause. PTFE composite grease ensures lightweight transition in extremely cold environments.

6. Upgrading the load-bearing capacity of commercial vehicles

Light trucks often have their ball joints broken due to overloading. Thickened shell (3mm) and 50000 fatigue test certifications, capable of carrying high-strength freight demand up to 130% of rated load, reducing the frequency of commercial vehicle ball head replacement.

Product Operate Guide

1. Pre inspection preparation

Use a lift to stabilize the vehicle and mark the position of the steering rod before removing the tires

It is strictly prohibited to use only a jack for support! Need to cooperate with safety brackets

2. Disassemble old parts

Loosen the dust cover buckle, and use a ball head disassembly tool to remove the M12/M14 threads (to avoid deformation caused by knocking)

Check if the suspension control arm bushing is cracked, synchronous replacement can save 30% of labor hours

3. Installation and calibration

Apply MoS ₂ anti sticking paste to the conical surface of the new ball head and tighten it with standard torque (M12: 85N · m/M14:125N · m)

Reinstall to the original marked position, ensuring that there are no gaps on the installation surface of the steering knuckle

4. Final inspection must be done

Perform four-wheel alignment after tire installation (focus on checking toe in/camber angle)

Road test detection: low-speed full rudder turning, confirmed no "clunking" abnormal noise
