Z3 rear diff noise-urgent help please.

[Tibs]

Hi all.

We have been to see a Z3 this afternoon that is advertised locally in a private sale. We really like it and it all seems to check out ok. The only thing being that there is a constant 'whine' from the back of the car whilst driving along. Is this, or could this be, the rear diff bearings that I have read a bit about?

If it is, are we looking at it costing a fair chunk of reddies?

We need to let this guy know our decision in the next couple of hours, so any real help would be great.

Thanks all.

Tibs,

I can't help on the diff noise, but why the urgency? There's tons of Z3's for sale - and I'd say the 1st rule of car buying applies - if you don't feel 100% comfortable or happy with the car, then walk - there's plenty more out there.

Go see plently, dont ever set yourself on buying one car go lookat many and see what they do howthey should be etc... As mentioned there are many out there; does it have many mileS?

If the price reflects the risk of a new/exchange diff, sounds fair, if it doesn't walk away. As said, there's plenty out there.

If you aren't entirely confident in a potential purchase walk away. Plenty more fish...

Do Z3's use E30 or E36 based diffs?

Z3 use E30 style diffs

So there's plenty of LSD options to chose from, have a look on Ebay.
