Lower Tensioner Arms = Lower Control Arms?

[Jarola]

Hello,

My 07 3.0 has been having a bad vibration when I apply the brakes. It actually makes the steering wheel vibrate from left to right very fast. I though it might be that my rotors are warped. I took it into a brake shop to have them take a look at it. They told me that the brakes are fine. The problem is that both lower tensioner arms need replacing. I have been looking all day for a lower tensioner arm for the X5 but can only find a lower control arm...and that this is a common problem with the X5.

Can anyone confirm that these are the same thing? Anyone else have a problem with their lower control arms?

Any help is appreciated!
