E39 M5 - Leaky Diff

[edmundo]

Is this common, easy/hard to fix?? rough cost etc etc..

Anyone know of a good indi around Henley/Maidenhead?

That is all

No ideas on cost but make interesting reading anyway:

I Paid £350 odd quid to have mine done. But there other bits included in that price....Gearbox fluid + some breather hose's. I Used Bexley Motors Works (in the South East)

I've got the same prob on the soon to be mine e46 m3

Might have to get on to Bexley

I'm having mine done over the easter weekend (I think). When I get the bill I'll post it up, but I'm having lots of stuff done at the same time so it may be discounted?

I had a diff leak too, and had to replace # 15, after having replaced 17 and 18 without permanently fixing it. A small ridge had slowly appeared in the output flange, which was causing the leak. The mechanic was able to change that in less than hour second time round, whereas it was 2 hours the first time.

Very common. Get it done as soon as you can as your diff will be leaking fluid all the time, which isnt good for the internals.

Very common problem although most diffs will leak when they are getting on a bit as oil will escape over a long period of time. BMW quoted £300 to fo mine.

They will need to drop the diff down and pull the half shafts out rather than dismantle the suspension and pull the half shafts out buy moving the hubs. The latter is much more time consuming and may be the option taken by a garage not in the know. Better to take to good indi or dealers as will take less time anyway.

A mate had the same and got it fixed for £300 ish from Bexley motors. Stealer wanted £500+.

Cheers guys.. As always a mine of useful info.
Bexley is a bit of a hike, will look for a good indi in the area.

I'll post up the score when it's all sorted.

Try Either of these :

Give Gary @ Autobahn Services a shout. He is in Rickmansworth and although a tad unusual really knows his stuff, has years of Alpina a M experience.

Also drop Phil Crouch a line at CPC. Currently in Marlow but soon to be moving to Chorleywood. Tel [phone]
