Rear axle/diff has gone...

[Skyracer]

On the latest track day, the rear started to sound more and more whining and grinding.

And on the way home it was sounding like a jet-plane. A terrible grinding noice. The diff was full with oil but what came out was not a pretty sight, a grey thick fluid with metall in it.

So the question is, what do I do now?

Open it up or just buy a new (used?) rear axle? Im not that mechanic to open up and look and fix the bearings and things.

What is the price of a used one in Europe?

Open it: it cost nothing to take a look and see what's dead inside

Yes, I have the workshop here at work so no problem with time, lifts and all thinkable tools and if its a bearing or two no problem and finding it, but knowledge...

I tried to open it but I couldn get it off (the plate in front of diff) after disconnecting the propeller shaft.

I losened all the nuts in the diff but it would come of, like something is holding it from inside. Do I have to remove the rear axles first before I can remove the diff?

Yes you have to remove the halfshafts (drivaxlar) first then the diff house should just come right out. Knowledge isn't a problem if you use the service manual

Thanks.

The Service Manual (AE86Manual.pdf) doesnt tell me to remove the driveaxles before the diff, what I can see. It only shows a picture of the parts of the diff. ( Page RA-8 ).

EDIT: My bad I see now.
2. REMOVE REAR AXLE SHAFT ( See page RA-3 )

Any progress on this?

I didnt have time this weekend but hope to take it apart this coming weekend.

I hope its not that hard to remove the axels (?) so I can remove the pinion and diff.

I feel (and hope) that it is the bearings (front and/or rear) for the pinion that has broken making the pinion go off line...

Chances are pretty slim for that m8...its usually the r&p that gives up...

Removing axles isn't so difficult. I did it and was surprised how well it went. :wink: .

Unless its the first time in yonks that you take them out, then it can be a bitch of a job. Make sure you have a slide hammer or something improvised that resembles one when you take on this job. If they have been out recently you can often take them out with a few gentle taps of a rubber mallet (or just by hand), but if they are rotted in there it will be much much harder (the bearings are 3+ cm's wide, that's a lot of surface).
