There is also the Chevy lean. A bit of that can be normal for some reason, but that left rear wheel. I'm thinking what is causing that, get it rectified, and the lean will be fixed. I have a feeling they're connected.
I had a buddy one time, said something was wrong with his 76, it leaned on the driver said. After a few jokes of letting fat girls drive it, I told him, it's your damn driveway. He always said NO. Finally one day I told him, quitcher bitchin' dude, it's your damn driveway. It don't lean when it's parked in the street. He says, that's because the right wheels are in the gutter compensating. I told him, you know what, back that fukin truck up in the driveway. He gets out and looks then yells, WTF is going on here, now it's leaning to the right?
I said, yeah I know cuz it's your fukin driveway. He argued with me some more claiming his driveway is flat other than the front to rear slope. I told him, it's a nice day, why don't wash the damn thing. As soon as I seen the water flowing, I told him to look at the flow of the water off your driveway. He didn't get it. It was flowing off the left side. I told him that water is going that way because you have a damn crown in your driveway. We finally got out a 4 foot level and a 2x4 stud 7ft whatever, and I showed him he had about 4 inch drop from right to left in his driveway. FINALLY !!! I got him to believe me.
