Lower control arm replacement
 

Just got the old one off thanks to the 'how to' on the forum however, there is an electrical switch attached to the control arm that doesn't show up on any diagram and the clip that holds it to the control arm is broken....anyone know what it does?

Thanks,

Gary

that should be the level sensor. get a new clamp or use a hose clamp

Should be part #5, mine was broken too when i changed the control arms as well.

Thanks...but looks like #5 is just the hex nut....I can't see the clip on the picture...was that broken on your job? If so, where did you get the clip from?

Thanks,

Gary

Sorry, part #3. Regulating rod. It was broken on mine, I ordered a new one from the dealer at the time.
