I see what you did there!
Question; how do you get rid of the RGB whine though?? |

But they are illegal here (no ear obstructions including ear plugs, headphones, etc) allowed.
I was thinking of sound deadening, but that noise carries all the way forward through the metal.
On a more serious note, if you follow Porsche 356 engineering and logic; the front of a rear engine vehicle SHOULD be higher than the back for better handling and response. I think on a 356 this is easily shown by the old race photos. And on a bus, I've noticed that a stock bus seems to have a really light, easy steering too it. Whereas the same buses, lowered, need considerably more force on the wheel. |

I actually like RGB whine. It's one of those perks that make driving a stock height split great. |

The RGB whine is a result of straight cut gears. It will always sound that way, and only gets worse with wear. I use ear plugs when I drive long distances, but mostly for wind noise. At highway speeds the wind is louder than the engine/trans. Look for Hearos ear plugs, they come in a tan color that is barely noticeable to the fuzz.
Low buses have heavier steering because they generally use a wider, low profile tire on the front. Depending on what was done to lower the front, the steering geometry can be affected and cause steering issues. Stock height buses that have low weight rating passenger tires also have a heavy steering feel.
Not sure about the nose high attitude and whether it helps with handling on a rear engined car. Have you read anything that describes this? I would be interested to read the science behind it. _________________ nothing |

The tallest radial tires you can fit to keep your old bird up:P225 75 R15. Unless you have a barndoor,the same but R16. Hang em high! Watch em drive! |

Does this cause your speedometer to read slower than you're actually going? Very interesting. |

A very good question. Typically with originall bias-plys the speedometer was and is accurate. With the radials the error margin is 2-6 mph. Slower than actual. These vehicles being "ancient" actual speedo readings differ. Us the hobbyist-bus lover's should have our speedo's caliberated. If not with these tall radial's keep in cosideration,2-6mph error. Reason being,they are wider. Keep driving. Enjoy. Drive em high! |

most epic thread ever.
Mr white... just run bias plys. The bus will be happier and you can enjoy that 50s experience. my speedo is dead on with 670-15". We checked with GPS, and every speed trap trailer I go by, my speedo matches it.

How much rake the vehicle has is exactly why the steering seems lighter on a stock height bus. Stock height buses are almost always level or a little bit higher in the front, whereas lowered buses are almost always lower in the front than in the back. It's all an issue of caster. Buses were setup from the factory with zero caster angle built into the beam and having a saggy rear end will turn that into a positive caster angle, giving it a lighter steering feel. When somebody lowers the bus without building more caster into the beam and lowers the front more than the back, they end up with negative caster, giving the bus a heavier feeling steering. _________________ -Andrew |

Every body seems to be lowering their buses and putting beetle trannies under them. How do you take it back to stock height? |

Get some stock spindles (and a stock beam if it's been modified) and an RGB trans to fit your bus. Install, and drive. _________________ nothing |

You don't need to weld anything back in? Thanks for your input. |

No. If that's all that was done to the bus, installing the correct drive train should do ya'. |

so what should the ground clearance be from your steering box? _________________

With all the raising back to stock height going on, this will put a few companies on here out of business, with the flood of used drop spindles and axle/spring plate kits hitting the market.
Gather all the stock suspension stuff that you can! |
