Hey guys,

I've just discovered that my differential is broken. The car had been standing in my garage for over four months, and when I first drove it on Monday, there was a strange noise. At first I though there was a problem with the tires or bearings, but it really was the differential.

How do these things break? Too old (120.000km now) or was there too much pressure at some point?

I bought one from England. It's from a '05 S2000. Does this one fit to my '99 S2000?

Thanks
Ben

 

I don't think it's the Diff. When driving straight ahead the diff is not engaged.
Must be an bearing. I place my bet on the pinion bearing.
Could also be old oil.

And yes, the 05 diff fits in your car. There has been some minor changes to the housing and the bearings. But the attachments are the same.

 

Danke dir!

Well, that's similar to what I thought for the past week. I mean, a differential might break, but usually not in the garage.
Anyways, I let two mechanics look after it, and to be perfectly sure, I wrote to Honda. They called me the next day and send me over to someone who is particularly experienced with the S2000. And when this guy drove the car, he didn't think it was the diff either. But when he put it up and listend with a stethoscope, he was sure.

 

Yes, but I'm still sure, it's only a bearing inside the diff-housing.

Did you tried some different oil?

 

Yes, I did. There were some tiny little parts of metal on the magnet. The Honda guy said this wouldn't be too bad though. But there had been enough oil in the differential and after I changed it, the noise was still there.
