I had to get the half-shafts from the diff to the rear wheels welded and turned. The rust had eaten away bad enough that the wheel bearings wouldnt go on snuggly.
Crap.... |

That's a pretty serious repair! How much did it set you back?

This may be a stupid question but why repair and not replace? |

That's exactly what I was thinking. Probably pick 'em up for $25 each at the boneyard. Then you're not worried about your half-shafts being held to gather by a wing and a prayer. |

Well, there is a difference between the 323i and the 320 half shafts. Not the same according to the independent BMW guy that helps me usually.
Turning them was $120.00. New for a single one would have been $160/ea.

According to ETK and RealOEM the same half-shaft is used on 4 and 6 cylinder E21s and the E12s with the baby sixes (M20). The only difference, I believe, is '77-'79 and '80-'82.
A little research goes a long way. |

I understood the 320i to be 28mm and the 323i to be 30mm thick. |

they're not the same. I had a bad half shaft on my 323i rear disk conversion and tried to swap in my 320i half shaft in it's place, totally different diameter. I ordered a new one. |

I have got a 320/6 and I am fitting a M535 diff using a Fritz's Bits conversion. Any idea what my shafts should be and whether there the best ones to fit?
Also does anybody know if there are anybody who sells upgraded half-shafts i.e. stronger and lighter? |

Hi
Dave
You need the e21 drive cups and shafts, custom shafts no problem but they are £600 a pair. On an e21 i guess the cv joint is going to break first, so i would recon the ones you have and see how they last.
I have got through about 2 a year, but that's beacuse the way the exhuast is run over the inner one, it gets the heat, the grease turns to oil and seems to run out over a few months.

why don't you just make a heat shield and band clamp or tack weld it to the exhaust? Make sure it floats about 1/4" (5mm) from the surface of the exhaust. It can lower the surrounding temps by up to 100 deg (C). Sounds a lot cheaper and easier than replacing CV joints and boots several times a year. |

Hi
Thanks for the idea but, i need a new exhuast as this one fails the noise test at the local track, and also 5mm is about the clearance between the exhuast and the cv boot. |

The bad news is that bearing manufacturers dont make something to make up the difference. We checked the major bearing manufacturers and there was nothing. |
