what causes shaking?
You might know that I drive a 82 Rabbit pickup gasser. It shakes when
I drive it. It is directly proportional to road speed. At low speed, I can see the wheel turn slightly back and forth on its own. At high speed the whole truck shakes. At illegal speeds, the truck shakes violently. It has been a while since I have had the wheels balanced, but they have been balanced a few times with these tires a few times. I think that it changes greatly when I have the wheels rotated. I am thinking the one of the two front wheels are messed up, whether it be a bent rim, or 'f'ed up tire. I dont think that I have a bad bearing, but one of the bearings is original at 185k miles. I have been thinking of ditching my steel rims for cheap alloys. Anybody know where I can get aluminum rims that would fit this? |

Sorry to pounce on this, but the accepted wisdon is to have the good rubber on the front as it carries 70-90% of the breaking and does all of the steering. (and on a FWD, provides drive; the rears are there to stop the arse dragging) |

(BTW that 70-90% figure for brakes is generally not correct as well.). The problem is when a car goes into a skid, the most dangerous thing is to have the back tyres loose grip as that will result in you looking where you have been and not where you are going. -- Joseph Meehan Dia duit |

OK, I don't want to get into a flame war over this so I'll continue what I'm doing, you do your own thing, but I want to ask this question.. if the rears are doing so much, why do the fronts alwas wear out first on a FWD? |

It is not a question of which tyres are doing more or will wear out sooner. It is a question of what happens in an emergency situation. Where it not for the handling problem, I would suggest the best tyres on the front. After all you do want the best traction in mud or snow. You also want the best tread up front to reduce hydroplaning. However those who have done the numbers on the relative risks (between hydroplaning and loosing control) have indicated that the best in the back is better. I would be tempered to reverse that if hydroplaning was a more serious threat where I drive. Of course it all comes back to the idea that you should have four good tyres and not try and skimp on your tyres. They are the only contact you have with the road. -- Joseph Meehan Dia duit |

You are wrong, and dangerously wrong. |

Have you thought about checking your rotors I don't know if you have
rotors or drums on front sometimes you can get what is called Heat Checking or some call heat spots that can warp your rotors or drums you may wanna check those out too and see if you have any spots if you do you can always have them turned and then of course you will want to replace the pads or shoes whichever applies. Just a thought??? |
