My new to me 69 Chrysler 300 has what looks like the original rear axle, 8 3/4 -489. It's non-suregrip and what I presumed was the standard 2.76.
First pic - chalk mark at 9:00 on tire with a corresponding chalk mark on the bottom of the drive shaft.
As I rotate the tire and watch the drive shaft (both wheels in the air, car in neutral), when the drive shaft makes one complete revolution the chalk mark on the tire is at 6:30. (Second pic)
One complete revolution of the tire rotates the driveshaft approx 1.5 times.
What am I missing here? Doh!
Thx
