Does a "Mitchells crash book" or something similar have a page or two showing body / drivetrain dimensions to measure up, after structural body repair / frame straightening, ect?
Car has a vibration at the top of a 1/4 mile pass / 100mph or so.
Have checked everything we can think of including but not limited to - frt suspension parts for looseness/wear, alignment, driveshaft balanced, trans [auto] gone through, engine good rebuild [balanced], rear axle bearings, center section gone through, replacement leaf springs, ride height, motor mounts, trans mount, wheels, tires, pinion angle, ect, ect, ect.
Same owner for 20+ years, been chasing this forever. It is livable, but still annoying.
Spring is here and time for another try at eliminating this vibration.
Any suggestions would be welcome! Thanks in advance!
