My 85 Brat has some shakes. not always though. I assume brakes to be somewhat suspect, but she doesn't pull to any side when slamming the brakes, but there is a bit of steering wheel shake. Also, on the interstate, the steering wheel shakes a bit going about 55-70, but once I reach almost exactly 75, there's no shaking and its nice and smooth.

 

What's the problem then? One, or all of these things? I've had new tires and a balance and alignment done *maybe* 800 miles ago. I wouldn't think brakes would affect normal driving at those certain speeds, but I won't be surprised if that's the cause of the steering wheel shaking when stopping hard.

ball joints, tierods, and wheel balance

Wheel balance is my guess.

When I had the white wagon wheel rims, the only place that could get it right was a local dealer.

I've had a dry CV axle cause vibration. Went through everything else and it finally stopped when the CV failed completely and I replaced it. 

 

Good luck!
