Hi Dan,

The odometer says 18k (albeit due to the speed sensor not being reliable at times eg above certain speeds) - I suggest it's higher, say 20k.

However, I have paperwork from previous ownership that refers to a labour charge for "Diff removal/refit" in 2014, but no details of whether this was a rebuild or potentially a Diff replacement.

I've not got the car jacked up and have commenced with the dis-assembly.
Looking forward to removing a drive shaft and using the guide below to identify the Diff.

Hi

Out of interest why did you take it?  What was the general noise like before discovering this?

Thanks

Fair enough! The car was bought with a noisy diff. CC said it was OK but I'm told it was unacceptable.  Then the car was exhibiting unsettling behaviour on the road so it was taken out and replaced with a Tracsport after finding it like this. 

It's owned by someone who posts on here and who's taken the process further than most of us making comparisons with open diffs and gathering info from other owners. A pretty competent owner who is determined to understand exactly what's going on.  I'm sure he'll contribute if he wishes to. Unfortunately he has told me of friends with similar issues too. 

There is a chance of some duplication here, there are so many diff threads and 'tales of the unexpected' it's easy to lose track but I'm pretty sure these images are new here.

it's all a bit unsettling, a complete failure could lock the rear axle and cause serious harm.  I'm glad I'm sucking up the cost and dropping mine out after 5k.  It will be interesting see what sort of state it's in.

I've got everything now, diff, plus complete bolt packs for the rear suspension and axle, along with the braided brake hoses kit.  I'm also trying to sort new suspension through Meteor also, figured I might as well upgrade that too.

If I can use up the half tank of fuel tomorrow I might get cracking on my tear down too.  Sadly the fuel in the car is a mix of E10 and E5.  Following CC's recommendation i don't want to leave it with E10 for any length of time.

I don't think the risk of a full lock up is too great, though I wouldn't really know. This one is the worst I've seen to be honest and still the bits were well contained. It was beyond repair of course. 

Have another.

I think the worst that would happen is that the LSD would lock up solid so corners might present a challenge!

Peter,

Is that from a sintered or carbon Diff ?

It's a carbon plate diff, by the looks of things. It's a good effort, I though mine looked bad when it was pulled apart!
