Flat spots all four tires

Mark,

I know how it is with kids in college. Mine have finally all gotten through that and I hope are saving lots of money to take care of me in my old(er) age  Of course, since I live right down the road from MSU, they had to attend universities elsewhere - go figure.

Pulled the driveshaft today and still can't find the cause of some other drivelive noise. I wouldn't have much to do if I didn't have all this detective work on the car - HA
