CONTROL ARM

The control arm is usually composed of a long arm and a short arm, which are connected to the vehicle body and steering knuckle through ball joints and bushings. The control arm is mainly responsible for connecting the vehicle body and the wheels, accurately controlling the movement trajectory of the wheels. When the vehicle turns, it can effectively guide the wheels to turn in the predetermined direction, ensuring the stability of the vehicle's handling; when the vehicle is driving on bumpy roads, the control arm can buffer the impact force from the ground and gently transmit the vibration to the body, greatly improving the comfort of driving and riding.

BALL JOINT

There are 3 basic types of ball joints that are used in suspension systems: 

Press in — a press in ball joint design works on the principle of friction, or interference. The ball joint is larger than the hole inside the control arm or knuckle. When the ball joint is pressed into the control arm, a high amount of friction is generated that holds the ball joint tightly in place. 

Bolt In — a bolt in ball joint uses a mounting flange that bolts on to the control arm using 3 or more bolts and nuts. Many of the OEM ball joints on this application will come riveted only on the original vehicle. As they wear and need to be replaced, the rivets are removed, and the ball joint is replaced with an aftermarket bolt in design. 

Unitized — a unitized ball joint application replaces the individual ball joint. This design completely integrates the ball joint pivot into the design and construction of the control arm assembly, forming one solid container arm. This design has become very popular with the use of aluminum design control arms. Replacement of unitized ball joints requires the entire control arm assembly to be replaced.

TIE ROD ENDS

Metal design of internal components — Internal metal designs are widely used in the manufacture of TOBRO tie rod ends. These designs incorporate highly durable upper and lower metal bearings that surround the tie rod end stud and ball, and they include grease fittings to allow for grease and lubrication to be injected into the central area to prolong the life of the tie rod end. 

Greaseable — Greaseable tie rod ends enable the joint to be serviced, to flush out old grease and contaminants by injecting new grease during inspection and maintenance routines. 

Black oxide coating — The black oxide coating provides high resistance to variable corrosion factors such as road debris and adverse road and weather conditions, ensuring prolonged life of the tie rod end.

Stabilizer Link

Metal design of internal components — Internal metal designs are widely used in  stabilizer links. These designs incorporate highly durable upper and lower metal bearings that surround the ball joint stud and ball, and they include grease fittings to allow for grease and lubrication to be injected into the central area to prolong the life of the stabilizer link. 

Greaseable — Greaseable stabilizer links enable the ball joint to be serviced, to flush out old grease and contaminants by injecting new grease during inspection and maintenance routines.

BUSHING

Automotive bushings, though small in size, are indispensable and crucial parts of a vehicle. They are usually made of materials such as rubber and polyurethane, and possess excellent elasticity and damping properties. In a vehicle, bushings are mainly used to connect different components, such as the control arm and the frame, the half - shaft and the differential. They can cushion the impact forces between components, reduce the transmission of vibration and noise, and provide a more comfortable driving and riding experience. When the vehicle is turning or braking, bushings can skillfully adjust the relative positions between components, ensuring precise vehicle handling. If the bushings become aged and damaged, it will lead to issues such as abnormal noises during vehicle operation, decreased handling performance, and abnormal tire wear.

MOUNTS

Automotive mounts, that is, automotive engine mounts, are indispensable and crucial components in a vehicle. Mainly composed of rubber and metal parts, with their unique structural design, they are widely used between the engine, transmission, and vehicle body. When the vehicle is in operation, the intense vibration of the engine generates strong impact forces. Automotive mounts can effectively cushion these impacts, reduce noise transmission, and create a quieter and more comfortable driving and riding environment. At the same time, they can also stabilize the engine and transmission, ensuring the normal operation of the power system under complex working conditions and maintaining the vehicle's handling stability. They are a powerful guarantee for the smooth operation of the vehicle.
