Quick chasis question for the gurus

Terrance28 · 02-17-2011, 08:56 PM

I am replacing my passenger rear control arm. While doing so I looked at the drivers side rear control arm and noticed that there is a sensor connected to it. There isn't a sensor on the passenger control arm. Is this normal?

Here is a pic of the sensor on the drivers side rear control arm, is there suppose to be a sensor like this on the passenger rear control arm as well?

If youre removing that arm, then remove that leveling sensor. 10mm nut and pull out.

So a sensor is suppose to be on the passenger side rear control arm?

Tee212 · 02-17-2011, 09:20 PM

Hmmm mine was on front n rear driver side, theres nothing on the pass side.

Yea I think that sensor is only on the driver's side.

It might be part of the leveling system for the lights and alarm???? Maybe part of the stability system? Just a guess.

It's the headlight level system. One's on the front and one's on the back. It looks like the front is on the driver side and the rear is on the passenger side.

e90pilot when you say the front and the rear. Do you mean the front and rear of the car, or the front and rear control arm?
