Just thinking, is it a shake at 60-75mph or when you floor it and hitting 60-75 mph in those first few seconds :eek:...don't think you'll get red of that shake?? :D
It is nondiscriminate as to how quickly you get there. That is the typical cruise speeds and it shakes. Thinking about it now further, one of the hubs had the drum cut loose from the studs, I wonder if that is the culprit. Maybe a drum replaced? Non balanced assembly?
