I have about 5500 on my 2011 EB and a problem that it's been mentioned to the service writer 3 times now and no resolve. When braking and the speed drops to about 43->38 or so the steering wheel will shake L/R slightly. Enough that I can tell what speed range I am in without looking.

It doesn't happen any other time or speed and is a bit more pronounced with a full tank of gas. My thought on this is a rotor problem and existed before I put on a leveling kit, back to at least 3000 miles when I noticed it.

I"ve mentioned it 3 times when I've had it in for this or that, every single time the tech reported that it could not be reproduced and was dismissed.

I am on the right track with the rotor(s) needing refinishing aren't I? I've tried putting it in N and braking and it still occurs and also coasting through that speed and nothing either. Only when braking.

any ideas guys and gals?

 

the fact that the vibration is so precisely located in a tight speed range would seem (to me) to indicate an alignment issue.

If it were the rotors then you would feel it over a wider range of speeds.

But then why does it only happen when braking? Maybe braking compounds the alignment issue?

Just guessing here.

Have you tried driving (you drive) with the tech in the truck? That way you can be sure it happens when the tech is present.

I'm guessing when the tech says "no trouble found" he might really be saying "this vibration is too little for me to worry about". Keep after them

 

sounds like warped rotors to me, how's lightly hitting the brake pedal at highway speeds? Should be crazy bad wheel shake if the rotors are warped

 

Not that I can feel and I know what you mean it should be more pronounced at higher speeds. The only place I can feel it is in that 43-38 (thereabouts) range.
