What are front thrust arm bushings?
Thrust arms and bushings are responsible for controlling the movement of the suspension for a smooth transfer of energy and pressure from your vehicle’s wheels to the frame. This takes place when there is a change in the direction of inertia on the suspension, most notably during braking.
Is a control arm the same as a thrust arm?
The thrust arm is longer than the control arm. It takes on a steeper angle and rises higher to the frame, and thus is also called an Upper Control Arm. It handles much of the longitudinal (fore/aft) car jarring, and consequently takes on much abuse and wear. The control arm is shorter.
What is a BMW thrust arm?

Usually, it is a steel bar or rod that runs through the inside of the neck, beneath the fingerboard.
What do control arm bushings do?
Control arm bushings are located between the control arm and the frame of the vehicle. They are important for tyre alignment and directly affect tyre wear, handling, and vehicle control. Most cars use one or two control arms per wheel, on both the front and rear suspension, with each arm housing two bushings.
What is a thrust strut?
It is the longitudinal suspension link in the front suspension that locates the wheel hub for and aft to the chassis. The thrust arm bushing can develop a leak and lose its dampening fluid, which requires replacement of the bushing.
Do you need an alignment after replacing control arm bushings?
Drive with bad control arm bushings is not safe. Because when the control arms or bushings are worn or broken, the steering becomes unpredictable and dangerous for you and other drivers. Even if you keep the steering wheel straight, your vehicle may be driving randomly to one side.
Can you replace bushings yourself?
Do you need an alignment after replacing control arm bushings? The control arm bushings don’t actually affect alignment. They just help position the arms properly during suspension movement. If they are destroyed, yes, your alignment may suffer, but you’ll notice steering issues before that.
What’s a lower control arm?
Bad bushings here can lead to popping noises, irregular wear on your tires, and a shaky steering wheel. It’s relatively easy and cost-effective to replace these bushings by yourself — with the right tools and techniques.
What is a thrust arm on Mercedes?
When should you replace your bushings?
- Excess vibration and road noise in the cabin of your vehicle.
- Friction sounds like creaks or banging coming from the wheel fenders.
- Any kind of frame rattling upon impact (from bumps or other rough road terrain)
- Overly loose steering.
Is a tension strut the same as a thrust arm?
One end connects to the wheel assembly and the other end connects to the framework of your car. The upper control arm connects to the uppermost area of the front wheel and the lower control arm connects to the lower most area of the front wheel, with both arms then attaching to the frame of the car.
Should I replace ball joint or control arm?
Real OEM calls them tension struts and wishbones. I’ve also seen them called thrust arms and control arms. … but yes, they are all talking about the same two arms per side.
How much does it cost to replace a control arm?
The replacement of a ball joint which is pressed into the track control arm, in most cases requires a removal of the track control arm. You should therefore consider replacing the complete track control arm.
Do control arms include ball joints?
A new car control arm usually costs between $400 and $550. Labor costs—if you take your vehicle to the mechanic to have the control arm replaced—will add on another $150 to $200.
How do you replace a front end ball joint?
Should I tighten or loosen the truss rod?
A control arm connects the wheel hub and steering knuckle to the frame of the vehicle. They are typically equipped with bushings on the frame side of the vehicle and a ball joint on the wheel side of the vehicle that allow flex and controlled movement according to road conditions and steering input from the driver.
When should I tighten my truss rod?
Remember in a single action truss rod: tightening the rod (turning clockwise) straightens the neck, loosening (turning anti-clockwise) permits it to bow.
How do I know if my truss rod needs adjusting?
If the bow is quite large, it means you need to tighten the truss rod. A large bow is caused by too much tension from the strings, so tightening the truss rod will compensate for this tension.
What happens if you don’t replace control arm bushings?
Your truss rod needs adjustment when the neck of your guitar has too much or too little upbow or too much backbow. Tightening or loosening the adjustment nut adds or lessens pressure on the rod and neck.
Is it hard to replace control arm bushings?
Like the cartilage that protects knees and elbows, when bushings wear, it puts more stress on the joints and connected parts. Like bone-on-bone contact, worn bushings can allow metal-on-metal contact. Worn control-arm bushings can allow the vehicle’s front end to slip out of alignment and cause premature tire wear.
How do I know if my control arm bushings are bad?
- Clunking Noise. Specifically coming from the control arm and usually following a bump, braking, or a hard turn.
- Steering Wander. Pulling to the left or right without input from the steering wheel.
- Un-Even Tire Wear.
- Vibration.
