[oletrucks] Front End Vibration

[Steven Moree <smoree@sbcglobal.net>]

I have a 1949 Chevrolet 1/2 ton pickup that I subframed (1974 Camaro 
front clip).  The front end has been rebuilt - all new A-arm bushings, 
ball joints, idler arm.  Occasionally, at about 40-45 mph I get a front 
end vibration that I feel back through the steering wheel.  If I speed 
up or slow down it stops.  I've had two different sets of wheels and the 
wheel/tire combination is balanced.  The front end has been aligned.

Any ideas on what could cause this?

Any suggestions would be appreciated.

Thanks,

Steve
