Ok, I took my 1963 Gasser Nova out today for the first time since winter and when I turned onto another street after stopping at a stop sign, I was pointed straight and really gave it the gas, broke the rear tires loose, hit the rev limiter (not hard to do since I lowered it to 5500 rpm) - it developed an incredibly violent steering wobble. I hit the brakes and brought the car to stop to get it to quit shaking violently and then after that it was fine. The only things I have done to the front end was lube all the fittings on the steering assembly and set the tire pressure at 34 psi a couple of psi higher than it was but it had bled down over winter time. Additional note: there is no steering stabilizer on the steering assembly. It has a Speedway gasser front end clip & a Vega steering box from Speedway it has what I consider to be a bit more play in the steering box than I like so I'm going to takeout the slack in the steering box (I also did tighten up the steering box a bit right after I got the Nova - so it appears the violent shaking loosened it up a bit again). Is it a toe out mis-alignment issue ? Loose rod end? Wheel bearing gone bad? When I aired up the front tires did I change caster enough to cause this? Did the rear tires breaking loose in combination with the rev limiter going off combine to setup a harmonic vibration that started the wobble? Anyone have any idea how to solve this problem so it never happens again?
