I am getting a rattling sound from the steering column when

Customer Question

i am getting a rattling sound from the steering column when i apply my brakes, almost like a relay chattering, but you can feel it in the steering wheel
JA: How many miles are on the car? Has the car been starting normally?
Customer: 150000, starts great, drives great, just when i start to apply the brakes..the harder i apply the brakes the faster the noise will cycle..sounds like a machine gun sometimes
JA: What is the model/year of your Chevy?
Customer: 2007 equinox LT
JA: Are you fixing your Equinox yourself? What have you tried so far?
Customer: just starting to look in to it, changed the front tires, had the brakes redone six months ago, was going to check if there was some kind of linkage in the steering column or maybe a sensor that was out of alignment
JA: Anything else you want the mechanic to know before I connect you?
Customer: i cant think of anything

Hi Im David, thank you for visiting the site, Vibrations while braking come from warped brake rotor/drum surfaces. As you drive the vehicle more and heat builds up in the brake rotor/drum then the unevenness becomes more apparent, So just replacing the brake pads does not help the vibration. The rotors need to be replaced . Make sure that when reinstalling the rotor/drum that you clean all of the rust and corrosion from the hub mating surfaces. The other thing worth checking is the front suspension and steering parts,make sure they are all in good shape and nothing is excessively loose.

did the brakes, that didnt help the problem. have not had them rechecked yet. was told there may be a sensor of some kind in the steering column or a linkage..that has been know to go bad...how that be checked with out taking the steering column apart?
Expert:  david craig replied 6 months ago.

there is no sensor that would cause that. you need to get the front end up off the ground and inspect the inner and outer tie rod ends and ball joints for excessive movement.

make sure the stabilizer bar links arent broken also

nothing really on the the steering column, except having the electronic steering module reprogrammed. but its not a recall. you would be responsible for the cost.
