Well I am also having this steering problem, exactly as described in the many other posts in this thread... highway speeds, warmed up truck, good tire pressures, no lane assist system on my truck... was most noticable sticking in left turns but I also sensed it lightly resisting me in right turns, quite scary at highway speeds I must say. Accurate smooth controllability at highway speeds is a must, now I’ve got to go throught the pain of trying to convince my dealer I have a safety problem when there are no long highways close by... ugh. Wish me luck folks.
@RamCares I might be asking for your help with this one too after I bring it in to the dealer.
