It looks to me like his toe-in specs are wrong. Looking at the linked spec, 25’ is almost half a degree, and -10’ would bring it to 1/4 degree so you should always be at a toe in situation. He has you at zero.

Lesjofors are the ones I use. They all sag at this point, replace the set of four.

Parts Geek carries them for reasonable.

That's the only thing that jumped out at me to.

What's the spec on included angle? At nearly 21 degrees, your measurements may indicate frame damage on the right side. Has this car ever been in an accident?

I suspect the car was sideswiped some time ago but on the driver side. The car fax on this car does not indicate an accident but i think there is some evidence of body work. The PO always had it serviced at the dealer (for 20 years) so i imagine he would have taken it to a reputable body shop.

I used a digital laser-type thermometer on the hubs after highway driving and there was no significant variation in temperature between any of the wheels so I don't think the bakes are causing it.

OK. So...

The alignment shop looked at it again. They cannot find anything that is bent but the ride height in the back is over 1 inch lower on the drivers side than on the passenger side. He thinks it is the rear springs. What do you think?

I confirmed the measurements. The back ride height is about 1.25 inches lower on the drivers side

Swap the springs around and find out.
