I need Z4 E89 differential all internal parts

[gunaygurer]

Hello, I have a 2011 Z4 E89 and have noise coming from differential. I took my car to service, they open differential and saw that internal parts weared down. I'm looking for somewhere to buy all internal parts but cant find. BMW sells only as a complete differential block. Is there anyone who can help me?

You should be able to find someone that can rebuild it. Years ago I had the differential refurbed (due to whining noise) on my E46 by a axel / diff specialist in Watford. it costs me around 450 GBP at the time. Alternatively you could take this opportunity to fit a LSD.

Thanks Silverstar. I am not sure if it is possible to do it. The contact points are looking like they are sanded. I'm not an expert but my local service engineer told me that they need to replace it. I'm living in Dubai and it is hard to find a professional on such jobs in here. How this job is done? I've attached a photo of one of the worn part

Perhaps if you contact a diff repair specialist in the UK they can supply the parts and ship it to you. If they won't ship it you could arrange the shipping from a site like parcel2go and have it collected from their place. I can't remember the name of the place in Watford but looking online I found this one:

Southern Axle Services
194 Queens Rd, Watford, WD17 2NT Directions
Tel 01923 230085

Which I think is the same company but like I say I dont remember also dont know if they are still active. You can try contacting them and see if they can help, otherwise you can google for other diff repair companies in the UK.

Thanks for the information, I'll contact with them to check what can be done

The other option is to get a second hand one from a breakers but the problem with that is you won't know how good it is. Probably you will be better off just rebuilding it.
