No and No.
Thanks for all your replies!
Ok my problem started as a strange noise when braking, like it was catching but it was rather loud. Initially I thought it was a warped disc, so I replaced that... it didn't fix it.
I took it to a garage where I know the staff and they used a laser thing (can't remember what it's called) and it showed movement in the hub so we/they assumed a bent/warped hub.
I bought one off ebay and waited for it to arrive. In the mean time I started getting another noise not when braking from the opposite side. This confused me again!
So today they fitted a new (2nd hand) hub to it, only for the issue to still be there except it has moved sides so now on passenger side. After a bit more investigating the found the culprit was the diff. Apparently there should be some movement at either side of something (sorry not sure what) and it was only happening on one side. They spoke to some diff specialists about it and apparently its not worth getting it fixed, better to just buy a used (or new if feeling flush) one and fit that.
Which brings me to here and my questions
So is there anyway of searching via my reg or anything to determine what sort of diff I have by any chance?
Thanks again for your knowledge fellow zedders!
P.S my zed seems quite basic specced from what I've read - cloth seats, no nav, not bose, standard wheels so perhaps it is just an open diff?
