[Chevelle-List] frames & whatnot

[Craig A. Ellis]

Well, in the effort to chase down my driveline vibration, I finally took the car to a frame specialist and paid him to dimension the car from stem to stern. His response: The frame is perfect. Never been hit, never pulled, never even been tied to the floor. It's square, the rails are the correct length, etc. BUT, the rear axle still does not LOOK exactly correct. He says optical illusion - the numbers don't lie. What I THOUGHT was a thrust angle problem turns out to be a CAMBER problem. The search goes on. BTW, he echoed that vibrations are almost always the driveshaft or connected parts (flange, output shaft, etc.).   Craig E.
