Hr31 Diff Fix

[sr20det510]

Can Anyone tell me where i can find replacement parts for an HR31 or a DR30 IRS R200 LSD.

Are any of the parts interchangable with later modle R200's?

My Crown an Pinion need to be replaced but ill be buggered if i can find the parts. Seems pointless buying another 2nd Hand diff which could have its own set of problems.

Regards

I would be looking for a good 2nd hand open diff in the right ratio and swaping the rebuilt hemisphere . Differentials rarely chew out the crownwheel and pinion teeth . You could open it up and check the teeth (backplate off) . Its probable that the backlash settings (washers on the outer sides of the carrier bearing outer races) is not set correctly which gives the clonk noise between drive and overrun . R200's are pretty tough diffs and it takes huge abuse or no oil to really kill them .

The hardest thing to do with any diff is to set the pinion height in the housing , without factory tools and lots of hours assembling and disassembling changing the ratio is very difficult .
