I've tried wheel bearings, tie rods, wheel balance and alignment but my shimmy over 60mph is still there! what's next? Ball joints? Bushings??

Bent wheels. BTDT, go see how many balance weights are on all your wheels. You'd want the ones with the least amount of weights on the fronts -but that may mess you up if you have directional tires.
I had a wheel with 21 1/4 ounce balance weights on them. just a "little" shimmy ha! |

Any good tire shop should be able to put your wheels on a machine and tell you real quick if there's a problem with a wheel or tire. Easy and quick thing to do next before digging deeper.

I'm betting it is the tires. I just ran across this recently. The tire balance machine doesnt know when there is a seperated belt in a tire. It wont show while balancing (no weight on the tire).

Ok. But, can't you visually examine the perimeter while it's spinning on the machine and see when things are out of round or untrue even if the machine says it's in balance? |

rust free you say ? Group: Members Posts: 16,375 Joined: 7-January 05 From: richmond, Va. Member No.: 3,419 Region Association: None |
Look at the tires straight on withh full pressure and if it/they are cupping in the ceneer get new ones. Tires will actually seperate internally, and start to pull apart and wobbling is the first sign. Ask me how I know (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Had a tire pulling apart on a CJ-7 with 33-12.50's. Fun ride! (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)
Does this pass the Capn's info test ??? I don't want to be a sinner |

Not easily. 99% of the tire machines nowadays are OSHA compliant with a big fat cover over the spinning combination. A lot of the tire issues wont be "visible" unless their is weight on the tire. B |

What year struts and what year wheels do you have?
Early Pedrinis won't mount flush to a later car, and will cause a shimmy that balancing won't fix. If the wheels are balanced off the car, you won't see it. I speak from experience. |

To check out my wheels, I had them dismounted and then put the wheels alone on the balancing machine.
