We need a new rear bearing for the chump car.
I noticed FAG are 38 and SWF are 82 from the bird board. Is the SWF better quality? Will the concours judges ding us? :-) John |

FAG (Fat American Guy)= 38 - cheaper, but I don't swing that way.
SKF (Southern Kinky Female) = 82 - a little more of everything ! I have used both. They are equal in wear. However you must look at the material specifications to really know. Check Ball bearing material and process. Check Race material and process. ~ http://www.fag-skf-nsk.com/en/channel/fag-...ements-569.html This site has the normal mumbo-jumbo, but take notice of the ethic of design by failure mode determining material & processes. |

Remember, these days, e v e r y t h i n g is made in China.
Even though SKF is a Swedish company, they get their stuff from the same people using 142 + vendors. Go german if you can. They make the best bearings. |

Have used just about every brand of sealed cartridge bearings known. I've smoked a good FAG and banged an SWF. Had both last and both fail. Both are decent brands. Luck of the draw. Based on average cost I go with the FAG but have been known to find SWF's cheap once in a while.

Thanks Dave! Checking the material used is beyond my pay grade. If people have had positive experiences with FAG it would help to know. John |

Check the car you are putting them into...
FAG will be perfectly fine. |

The bearings seem to be shifting to different parts of the world depending on the production run. I have seen both FAG and SKF made in Germany, France, Spain and Mexico. These changes have been occurring from the 1980's to present. Both are good bearings and equal in quality. The price seems predicated on previous name recognition.

Don't know where I bought them without looking at a gazillion receipts,
But I put in two and one is bad out of the box Now I need to redo a trailing arm 50/50 who it is. |

In the end, installation technique makes the biggest difference, hands down.

The Cap'n I like how the Pelican article says you need to use the Brute Strength and Ignorance (BS&I) method to remove the old bearing... (IMG:style_emoticons/default/smash.gif) From the Pelican article it seems like pressing on the outer race of the bearing to install the bearing into the trailing arm, and then only pressing on the inner race when installing the hub are keys to not damaging the new bearing. Anything else to watch for? John |

In the end, installation technique makes the biggest difference, hands down. Here is how Porsche recommended doing it. Rear axle bearing is installed using tool P302. Wheel hub is drawn into bearing using tool P298b. Tool is first threaded onto axle shaft. Tool P298b wheel hub installer Tool P302 bearing press pad Jon B. Vista, CA |

They make the best bearings. SKF = Schweinfurter Kugellager Fabrik A very old German industrial company These parts are DIN-Parts with the same specs from any vendor in Germany DIN=Deutsche Industrienorm=German industrial norm (standard) |

Don't use SNC made by the Frogs. I have had a bad experience.

Anything else to watch for? John Think about the bearing and its construction, along with all the friction and force you create while installing the unit. When pressing it into the hub, all the friction is on the outer race. If you press on the inner race, you stand a very good chance of twisting, bending, or racking the bearing. Then, when you go to install the inner stub axle, all the friction is on the inside of the inner race.... So, hold that in place when pressing. I remove the trailing arm, bring it to the press, and do it there. Rich |
