I would think that they should be almost silent, any kind of dry rumble suggests trouble ahead I have a bearing number somewhere I will look it up |

I finally completely dropped the torque tube down earlier and recorded the noise, I can see the grease has come out of the bearings as well and the sound dry. Transmission end sounds the worse, maybe because of the additional weight of the coupler on the shaft? I've contacted Augment Automotive and they are able to rebuild my existing torque tube with FAG C3 rated bearings (I believe the original were C5 and rated for high temperature). I've done some searching and can only find C3 off the shelf, some NOS C4 by INA on ebay and a reference to requesting C5 bearings which were C3 bearings that were re-worked by the supplier (SKF) to C5 tolerance. There are also Constantine's Super Bearings from the US but after shipping and customs that would be the best part of £1000 in parts alone |

Ouch, that’s a lot of money for some bearings |

I exaggerated slightly but still not cheap! the super bearings do come with new heavy duty bearing carriers though and are claimed to be suitable for v8 swaps and high power custom turbo engines etc... Design 911 have some 9products bearings which come with a bearing carrier as well which is slightly different to the super bearings and about half the price - https://www.design911.co.uk/fu/prod1470 ... =doofinder £440inc VAT |

Done a couple of rebuilds of t/t , it’s not that difficult . From memory 4x bearings were £30 and £20 to powder coat t/t . There’s a few guides online to follow . I got mine from Wych Bearings 4x FAG 6006-2Z-C3 if that’s any help . |

What method did you use to replace them and what condition were your bearing carriers in when you removed them? Augment offer a full rebuild including painting for just under £500 |

Removal I used 1/2 galvanised tube over spigot bearing end of driveshaft to protect it and a few heavy hits with a lump hammer then a 3" round post and a few heavy hits with a sledge to remove carriers after lubricating tube . Installing I used the threaded bar method after using soapy water to lubricate tube again . The carriers have all been reusable but I did have my local engineer pin the bearings in the carriers as I wanted to make sure this was done correctly .

Thanks - I think I will do it myself then, I was trying to save time by farming jobs out but there is potential to save a few £££ keeping this job in-house Just look at getting a 6ft length of 1/2" steel pipe |

The carriers have all been reusable but I did have my local engineer pin the bearings in the carriers as I wanted to make sure this was done correctly . Maybe I'm not doing it right but it has taken me almost 2 hours just to get about 1/2 metre of the shaft knocked out of the torque tube carrier. I'm using some galvanised conduit which fits nicely over the spigot end. Have you had any that were difficult like this? I think that possibly the front bearing nearest the engine end of the tube is moving backwards with the shaft... I'm using a sledge hammer and it's making a mess of the end on the galvanised conduit Left it for today and will have another go tomorrow |

Have a look on you tube , there is a lady showing how its done " 944 drive shaft removal from torque tube " . I have not had to much trouble removing driveshaft , might help to let a bit of oil penetrate over night to try and lube driveshaft . I have some spare carriers here if you need them , just be careful not to damage either end of driveshaft . |
