My issue was tires. I don’t remember the numbers off hand but one was out of spec so dealer was able to convince Lexus to replace all 4 and no issues since. Rides like a dream for a BoF truckI had DT rebalance on Thursday. They found the two on the passenger side were out of whack. Flashed some numbers like 4.5x for one and 1.79 if I remember correctly with the other two being 0's. GX rides better but I can still feel some vibration like before. Plausible that they weren't balanced right in the first place, but has me thinking that at least one of those tires is bad. Will be taking it back in a week to see. Had friends with the Nitto Terra G2's in the past that initially ended up with bad tires. Was hoping the G3's had better quality control.
