Hmm, not to argue; as I'm sure you know the system better than I. However, isn't it one of the Nexsteer torque overlay systems and allows parking assist and lane keep assist? At least their literature claims that it is or am I reading that wrong?

I'm trying to find the one where they specifically mention the contract with GM for the 3/4 tons - that says it uses the magnasteer along with torque overlay. - http://www.nexteer.com/news-releases/nexteer-delivers-adas-eps-like-functions/

I personally was under the impression the solenoid controlled a valve that allowed hydraulic fluid to turn the wheel (for operations like park assist). Rumor mill was the Ford F-250 was going using a similar system to include their trailer back-up assist.

The service manual doesnt make any mention of "active steering" capability, and I havent seen any documentation from GM indicating their system in the 2016+ HD's has the capability. Im sure it could be added though, as you said, through spool valves to direct hydraulic fluid at the input shaft of the box.

Hi all!

Amazing an hour or so after I sent a PM to GM Service on here - they called and said my new steering box was located and did a same day replace last Wed. Could be coincidence. Left Thurs for a week of camping, truck towed and drove perfect the whole trip. :thumb: Thank you all for your help - tons of great info! I wouldn't be surprised to see a recall as this was my 2nd NEW HD (one gas, one duramax) with funky steering issues. The gas one was so terrible that I traded it back in as I felt it was unsafe. I ate a few grand trading it in but was worth it to me.
