Hello Everyone,

I have a 185,000 Kilometers 2007 ES 350. I recently got all season brand new tires installed on it, along with wheel balancing and alignment. Yet the car keeps going right when I take my hands completely off the steering wheel. The drift toward the right is very small and if I just touch the steering wheel to cancel it, that is enough. I was afraid that my new tires will get worn out unevenly so I got alignment work done once again by a different tire shop that my mechanic recommended. I told the situation to the alignment technicians there. They told me that they have fixed the issue as best as they could and everything should be fine now. But the problem is still there. One thing that might be helpful in understanding the whole situation is that I got inner and outer right axle replaced about 6 months ago due to a leak. The right drift was always there, and I had decided to worry about the slight drift after I get new tires, which I have now. Please take a look at the following two alignment reports, and let me know how come a car can drift right when two alignments done within one month essentially report the alignment to be within manufacturer's specification:

Report #1:


Report #2:



I have the following question:

Q#1: If I leave this issue as is, will my new tires get worn unevenly ?
Q#2: Could this issue be related to the steering and not the alignment ?
Q#3: Does all cars slightly drift toward the right ? I ask that because someone told me that roads are built that way. I don't believe so but thought to ask anyway to get it out of my head.
Q#4: Is it normal to have slight left or right drift in cars anyway ?
Q#5: If this issue needs to be fixed, then what might be causing this?

Tell them to set TOE to zero.

Do you notice this on the road or in a parking lot also?

Roads will usually camber to the right for the US/Europe, so it's natural for your car to start drifting to the right, your alignment technician usually accounts for this in their adjustments.

Thanks for sharing this TSB. I've fought the "drifting right" issue with several of my Toyota/Lexus vehicles over the years. I figured out how to do the troubleshooting without the TSB, but wish I had it two decades ago when struggling with an Avalon. Luckily, my 2011 ES and 2008 SC430 don't exhibit the problem.

Most often, when you can't resolve the issue with an alignment, it is due to a tire issue, but not always. As mentioned earlier, the crown of the road is a contributing factor, but still, some vehicles are more sensitive to it than others.
