In automotive suspension, a control arm, also known as an A-arm, is a hinged suspension link between the chassis and the suspension upright or hub that carries the wheel.
The inboard (chassis) end of a control arm is attached by a single pivot, usually a rubber bushing. It can thus control the position of the outboard end in only a single degree of freedom, maintaining the radial distance from the inboard mount. Although not deliberately free to move, the single bushing does not control the arm from moving back and forth; this motion is constrained by a separate link or radius rod.
This is in contrast to the wishbone. Wishbones are triangular and have two widely spaced inboard bearings. These constrain the outboard end of the wishbone from moving back and forth, controlling two degrees of freedom, and without requiring additional links.
Most control arms form the lower link of a suspension. A few designs use them as the upper link, usually with a lower wishbone. The additional radius rod is then attached to the upper arm.

Thanks for share your video, very useful, Saludos cordiales.
OF COURSE!!! a fellow greek.thats why your so good.my family is from Kastoria in the early 1900's my grandfather was the largest fur trapper in that area so large in fact he moved to Brussels and his brother to Paris and opened stores selling Greek pelts to the fashion houses to make coats…..Long live greece.and all of its sons we will forever be the greatest
We cannot get the right control arm for the front here anymore. Can a metalworks, or engineering place fix the old one? Not sure what the brushes look like? Help?
Thanks for sharing good job

Bad replacement. You should tightened the suspension arm after u move the car down.
Can I get a list of all the tools I will need including socket sizes
ohh it may not pass thru the the top due to the frame in the way… hmmm?
I noticed he installed the bolt on the arm from the bottom up.. should put the bolt in from the top !! think about it????
Show, melhor video que vi até o momento! Parabéns Yiannis.
Olá bom dia! Você poderia me indicar qual saca bucha eu deveria comprar para trabalhar na suspensão traseira e dianteira do Toyota etios?
Same process, and control arm, for Toyota Zelas and Matrix, 2011-2014 Scion tC (rebadged Zelas), Lexus 200h, and Pontiac Vibe (rebadged Matrix)
Did you have to remove any parts before taking off the control arm? To make room for the bolts to clear?
What was wrong with your lower control arm? Why did you replace it. I have some rattle at low speeds when I go over a bump.
Wat size bolt was that on the screw u use the breaker bar with
Great job. Thank you.
wow not even English and its pretty straight forward. this video was very helpful.
