It doesn't. Quote: Not affected by cornering L/R at all? Not that I've been able to tell. Quote: Rattle as opposed to 'knock'? Erm, could be called a knock I suppose. Quote: Is it deffo wheel speed related, as opposed to (faster) prop/input speed related? Not sure I get you. When I say wheel speed related I mean that it's got nothing to do with engine speed or gear selected. I suspect you mean something more involved. Quote: Tried pulling the handbrake lightly while it's making the rattling noise? No, can do that tomorrow evening. _________________ blog | twitter Posted: Mon Apr 02, 2007 12:07 am Neil Established   Joined 22 Jan 2002 Posts 17309 Location Woking, Surrey Ian332isport wrote: I guess you won't need my trailing arm any more now . No, but if you've got a half shaft then maybe swapping that in to see if that eliminates it would be a good move over the Easter weekend? _________________ blog | twitter Posted: Mon Apr 02, 2007 12:36 am M3 Compact Administrator   Joined 18 Apr 2004 Posts 41051 Location Reality.

Is the regualarity as if something was catching a wheel every revolution, or does it sound 'faster'? Your propshaft is spinning 3.25 times for every turn of your rear wheels. Often propshaft/pinion (diff input) noises are discernible from output/shaft/wheel noises. _________________ Posted: Mon Apr 02, 2007 8:08 am Ian332isport 3 Series Moderator   Joined 26 Feb 2003 Posts 2350 Location West Sussex Neil wrote: Ian332isport wrote: I guess you won't need my trailing arm any more now .

I don't, but I know a man just down the road from you in Camberley who might. I've sent him a PM to see if he has one, and if he's prepared to let you borrow it _________________ Posted: Mon Apr 02, 2007 9:08 am Sundayjumper Advanced Driver   Joined 02 May 2003 Posts 1713 Location Berkshire/Surrey border M3 Compact wrote: All you need is the big socket (32mm?) to undo the nut, Neil.

Wheel speed, not prop shaft speed. _________________ blog | twitter Posted: Mon Apr 02, 2007 9:23 am M3 Compact Administrator   Joined 18 Apr 2004 Posts 41051 Location Reality.

I can't be 100% Simon as I hadn't given it any thought while in the car. The more I think about it, the more I think it may be three times faster than wheel speed. Not much use this morning, am I? _________________ blog | twitter Posted: Mon Apr 02, 2007 9:42 am M3 Compact Administrator   Joined 18 Apr 2004 Posts 41051 Location Reality. The diff isn't moving on the over run is it Neil?

(Allowing the prop to touch something.) I don't think so. The other piece of information that leads me to suspect that it's a problem that's internal to the diff, a joint or bearing is that it's usually much quieter when the car is cold, and reaches its full volume after about 5 minutes. _________________ blog | twitter Posted: Mon Apr 02, 2007 11:54 am bennyboy Driver   Joined 14 Feb 2005 Posts 437 Location Deepcut, Hampshire I am about this evening if you need any help with the wagon. Can provide one of my big sticky out ears to help identify the offending component! _________________ Boston Green E36 328i Touring Estoril Blue E36 M3 Evo Saloon, Subaru Impreza WRX PPP Posted: Mon Apr 02, 2007 11:35 pm Neil Established   Joined 22 Jan 2002 Posts 17309 Location Woking, Surrey bennyboy wrote: I am about this evening if you need any help with the wagon. Ah thanks Ben, but I was otherwise engaged tonight. I'm not sure there's much we can do now anyway without some more bits. Robin has ordered some diff oil, and if/or Ian's chum in Camberley turns up this half shaft I'll crack on with it on Tuesday / Wednesday evening if possible. Failing that it'll be Easter weekend.

Cheers, Ian. That'd be excellent Ian. I can probably get over to Camberley at about 7.30 tonight, or if Bennyboy's free, he may be able to get over there sooner if it helps. Thanks. _________________ blog | twitter Posted: Tue Apr 03, 2007 10:25 am bennyboy Driver   Joined 14 Feb 2005 Posts 437 Location Deepcut, Hampshire Neil wrote: Ian332isport wrote: Neil, Simon got back to me, and he has 2 or 3 spare shafts, and you are welcome to borrow one I'll ring him today to see how is the best way for you to tie up with him and collect the shaft.

Yep, available if required! I work in Farnborough (next door to Camberley) so not a problem. _________________ Boston Green E36 328i Touring Estoril Blue E36 M3 Evo Saloon, Subaru Impreza WRX PPP Posted: Tue Apr 03, 2007 10:29 am Ian332isport 3 Series Moderator   Joined 26 Feb 2003 Posts 2350 Location West Sussex bennyboy wrote: Yep, available if required!

He is however working on someones conservatory tonight, so will be going back out after 5pm until about 9pm. I've just tried calling Neil to discuss, but got his answer phone.
