RE: Steering Wheel Vibrations

Mitch -

Yup, wheel balance is most likely the culprit.

Usually starts somewhere between 50 and 60 MPH, and will go away at higher
speeds. Why it behaves this way I don't know, but it does.

One word of advice ... try to find a shop that has a wheel balancer
(dynamic, anything else is a waste of time and money) whose main business is
not tires. Tire shops beat on their equuipment 10 hours a day six (or more)
days a week, and seldom (if ever) calibrate the equipment.

I've also seen guys at tire shops not check the balance. IOW, the wheel is
mounted on the machine, old weights removed, spun, new weights added. Some
guys will stop here and remove the wheel from the machine. The wheel should
be spun a second time on the machine and should come up 000 indicating that
it is balanced and requires no additional weight.

High speed balancing is a misnomer ... once a wheel is balanced (statically
or dynamically) it is balanced at all speeds.

HTH,

Jeff (who couldn't find anyone to balance wheels correctly, so I bought my
own machine :-)

I'm wondering whqt the causes are of steering wheel viberations that occur
between 60 + 70mph. I suspect wheel balance but shouldn't that get worse
above 70? The steering is very precise and the tires are only a few years
old with plenty of tread left.
