Haven’t driven the car for a few months, but don’t recall feeling any vibration or other issues. Noticed the car had rolled back about 6” or so, as the lift arms didn’t quite line up on the frame where I had left it previously (lifted to drain radiator/coolant) figured dad may have moved it to get his snowblower out. Tried to roll the car forward back to where it was. Kept wanting to roll back. Figured maybe it was a flat spot in the tires.

Pulled a wheel off last night in preparation for a Vintage Air System install, and found a huge bulge in the tread. Don’t know the exact mileage these tires have, but can confidently say it’s well below 10k miles. Possibly less than 5k. Tires are about 7-8 years old, stored in a climate controlled garage.

Check those tires! Guess this is a broken or separated belt? (See pics below)
