We have an R200 differential, and I believe the mount/insulator is toast. It not only looks deteriorated, we also get a loud thunk under initial acceleration and braking. However, I'm told the R200 is no longer available new. Any body know where I can get my hands on one?

 

The differential itself..? Or the insulation?

Insulation can be made, if you have the materials.

My friend/owner of RHC Garage (Tulsa, OK) has made custom mounts for a few vehicles. I'll see about how much he'd charge for you, as I need one as well, it'd be nice to get the process down.

 

Nissan still sells them:

Or you could just weld it...

 

I was told there was a polyurethane one that works. I'll have to remember to ask my friend for the part number....
