One of the annoying traits of our 2003 Camry is a bit of wandering on the road. Changing tires and a couple of alignments still does not help. What it seems to be is the power steering assist is set too high. Makes steering much too light, therefore a minor road imperfection would kick the tracking out of line. This requires more correction on the driver's part to keep a straight line. Also the PS overassist makes turns a bit tricky, often causing a side to side swaying that mimics body lean, but is actually steering corrections during the turn. Making the Camry feel "floaty" like the old Buicks.
I recently drove a rental 2005 Subaru Outback and it has rock solid straightline tracking and tight turns. Loved the solid handling of this large car, though the Camry is better in other respects.
Is there any way to adjust the assist on the power steering?
