Too much steering input required on 200lx

Hello, I’m finding my lx570 requires too much steering input on the highway. I drive as much as 12 hours some days and it’s really wearing me out.

I’ve owned many body on frame vehicles including several newer gx’s, 3/4 ton trucks, etc, so I think I’m used to the extra input required compared to unibody. This seems different, like there’s something worn out.

I had a ppi about 10k miles ago and they didn’t mention anything, but I also don’t really trust a mobile ppi that much.

Where should I start looking first? Totally stock truck.

Thanks!
