Default on/off slight vibation @ cruse

I have a BBC 69 Camaro w/ TH350 & dana 60. Brand new balanced slicks, new front runners also balanced. U-jonts look fine, driveline seems ok. I am getting a on/off vibration that is constant @ at 50-55mph that is bugging me. Its slight... but stong enough to make my auotmeter guage needles vibrate on top of my dash off & on at that speed... idea's??

I had a very similar vibration once in a BBC 67 Camaro that turned out to be a small crack on the torque converter hub, where it engages into the front pump. But of course that's not something you can even check without taking it out

Well, it's good to know... i would not have thought about that. Did it leak or have any other symptoms? I am hoping I have a bent wheel or something simple.... haven't checked that yet.

No leaks or other symptoms at all other than the vibration. It was very hard to even see when I took it out too. It was just lucky I took the trans out for another repair and decided to check the convertor over real good(kind of already suspected it as I had checked everything else). But, hopefully yours is something a little easier to find.

if the vibration goes away at higher or lower speeds it could be a tire or wheel problem.sorry i didn't think of that till you said something ops:

No prob... took me awhile to suspect the wheel too... the RR is bent, I have no idea why (Weld Pro Star). When jacked up, you see it- its that bad!! question is, what the hell did i do??? looks like I will be buying a new one....
