Vibrations at speed on A&C

[John Poling]

PNJSNAK,
I will inspect mine and see if any cracks exist, but just to make sure of the location you are talking about, this is the area of the tube where the coilover mounting point is welded in?
Also, when I was putting my axle together I noticed that the axles wouldn't go in real smooth. I dismissed this at the time as I figured it was because everything was brand spankin' new and would be a little tight.It almost looked like the axle housing as supplied by A&C was not welded together straight so I took it to a frame shop for the alignment and they hooked up to all four wheels and didn't mention anything about rear axle mis- alignment. Did any of you notice this in your build?

aumoore,
I have contacted another shop over in Antwerp, Ohio that is a specialist in designing/building complete chassis systems and they are NHRA/IHRA certified. I will be taking mine to them for their input. I will try to remember to let you all know what the outcome is but it will probably be a couple of weeks yet.
I like the thought you posted and mentioned that to the shop that did my alignment and they kind of brushed it off however, they did spin the front wheels on the car and made a few adjustments but all in all they didn't do it right because I noticed a severe vibration in the windshield frame when he was spinning it. I mentioned it to him and he said that he was spinning it to about equal about a 90-100mph speed and that is well above what it would be driven at. I will eventually get this thing straigtened out, it's just a matter of time.

Thank you for the input.

Keep the ideas rolling in.

John
