[6pack] Shimmy at 50mph

[Robert Lang]

Hi,

Tire balance is really important. So is the shape of the tires and wheels. 
Make sure there's no obvious runout or wobble with those components.

Next, make sure everything is tight. This sounds obvious, but it's amazing 
how a car can run with parts shaking loose because they weren't fastened 
properly.

Then make sure that the shocks are working properly. Telltale signs 
include oil drips at / near the shocks, odd wear on the tires (somtimes 
your tire will "cup" when the shocks are gone.

Bottom line, vibrations and shimmies are always caused by something that's 
not balanced, not round or loose.

As far as your mechanic, we hope he/she was kidding. Any mechanic worth 
thier salt will love a client with an old car. It's like taking candy from 
a baby.
