Left lane pull
Anyone please tell me how much correction do you use on your steering wheel when driving on the highways in the left 1 or 2 lanes? My car has a drift and I feel that I am correcting or holding my steering wheel about .5 inch or so to the right side to keep it in the left lane. If I am in the right lane then the car does not drift left and has a very slow drift to the right due to road crowns on a multilane boulevard or highway. I had alignment done twice in the past 1 year. This leftward drift is noticeable with my current Michelin all seasons but no so with my winter Michelin tires so I just wanted to see if its a tire issue or its the car very senstive to road crowns. I basically time in seconds how long my car can stay in the left lane before it drifts out and its about 5 seconds. Other cars take about 10 or more seconds.
BTW, my right front wheel caster is more then my left front wheel caster by 0.75 degrees while everything else is equal on both side and in spec. I have been told different things about caster difference. Some say that the car will pull to the side with least caster while the Lexus chief mechanic says that it will not. I have swapped the tires from one side to the other in the front with minimal difference. Its a minor annoyance but something I am curious about. I know about road crowns but I want to see if others have GS that track straight for a long time at least several hundred feet or more ( more than 10 seconds in the left lane on highway without hands on steering wheel) before it drifts slightly out of the lane on the left side.

...I had some slight cupping at 6k so I had the dealership adjust the toe and now the car tracks straight.

Mine just passed 1,000 miles. On month old. I'll check the highway drift, but I have noticed a strong sideways pull when stopping. Usually pulls to the left, but sometimes to the right.

Yes I had it done free last year and this spring and the toe, caster, and cambers are all set but the left caster is on borderline out of spec even after alignment but it shouldn't cause the car to go to the left. I drove today and the car does not pull to left at all when in the right lanes. If in the middle lane it would go either way. If its in the right lane it would track straight but a slight drift to right but if in the left lane it takes more effort to keep in lane or more frequent correction of the steering.

I've also noticed when stopping and going over uneven pavement the car will pull to one side if I don't have the wheel held firm.

It happens on every lane and even on the flat and leveled surfaces as well. I'm going to check my tire pressures to see if any of them is off by a significant amount. I mean I had an alignment at my 5fk/half year service and it was still doing the same thing. Ive gotten used to it because my parents Lx570 does the samething

Sorry to bump an old thread but is this normal? I am noticing this too on my 2 week old GS with less than 400 miles on it. It will drift left sometimes on the highway. And when coming to a stop, the steering wheel would sometimes turn left or right if I don't have a firm grip on the wheel.

Generally far left lane. Which I often just attribute to the way our roads are banked. But the way the wheel turns itself sometimes is scary.

Can anyone confirm the mileage and months on this coverage?
