Did you look at the upper engine mount?

Tc is not my concern, but you could just push the button to turn it off. Those warnings come about because the wheels are not spinning.

My concern is that the CV joint is at it's max.

Unless there is some reason to suspect the axle shaft is bent it just won't tell you anything. There is a tool called a "straight edge" made for that job.

Okay. I will just forgo that check, and will look at that upper mount when I get home. Looking at the inner workings of an axle the only way I see it could be vibrating is if the shaft is bent, right?

It "could be" the CV balls are worn out. But that is pretty far down the list.

So my dad insisted on checking the axles with the car in the air, and I gave him the good old break it you buy it disclaimer. He assured me nothing could be hurt and he was right. We checked each side independently for safety sake. Traction control is disabled when the handbrake is engaged so that system was safe. Both axles spun round true, but my two front tires show signs of weather cracking in between tread and my left front has a noticeable flat spot when going around. We also ran the car in low gear. I've driving at least a hundred miles since without issue. Main thing is just to be safe. You may encounter what I did after going for your first drive and that is an abs warning. This happened to us because we only had one wheel in the air running, and when we apply the brakes before shifting to park the car thinks there is an issue with the system. On first start the abs light was illuminated, I proclaimed to my father "told you we'd break something" but immediately after rolling forward and applying the brake for the first time the light went away. My father did note play between the transmission and the tripot, but he knew there had to be some give to allowed the axle to move up and down slightly with the suspension. I'm getting new tires on Monday, we moved the two bad ones to the rear but it feels almost worse to me because now it shakes me instead of the wheel!

Did y’all check that upper engine mount?

Yes. LOOKS okay but it still is a rubber part it's probably hardened up pretty good I'll replace it someday since it's easy enough to. Gonna wait until I need a new serpentine belt

Look at the hole inside the passenger side fender if that bolt is more than halve way below it, your motor mount is shot!
Also look at the bottom of the mount if there’s an oil like goo there , it’s toast!

There's no need to wait, because the mount doesn't have to come off to replace the belt.

And even if you want to remove the mount to R&R the belt, it's good to keep the old belt in the cargo area as an emergency spare.

I've PMed Prod to see if he still has that pic.
