Sometimes, when an intermittent problem occurs which presents no clue as to what is wrong, we just need to drive it. The problem will likely get worse to the point that the cause will expose itself.
I have a '49 with a shimmy in it at 60 MPH after 2,000 miles of flawless driving at 70 MPH on the highway. It has all new everything, carefully adjusted to specs. It is not a death wobble, but I find it unacceptable. I can't find what is causing it so I plan to just drive it until it gets worse in hopes to find the cause.
