Prior to installing these, did you also do the BCM flash that provided more voltage to the headlights? I know the 14s experienced this issue and GMC released the following TSB # PIT5374B to address it. I'm trying to determine if the BCM update would be beneficial or if it's not needed with this new set of lights.
Thanks,

Is it possible for you to post the new rack part number? Also, are things still operating without any clicking noises and has the steering gotten any easier?
Ed,
Do you have the part number for this new steering rack? Dealer also mentioned that noise may be due to the EPS working harder due to the level and bigger tires. At this point anything is possible, but mine does feel more steering gear based. Although after trying to identify this issue from all different angles, I could just be reaching at this point.
