On the diff. The front 2 bushings are just rubber. The rear diff bushing is silicone filled. When that leaks. It will stain the diff cover.

On the rear sub frame. The front 2 bushings are silicone filled, and the rear 2 are just rubber. You can replace them with the SPL solid bushings, or use the Z1 bushing inserts. No one to my knowledge has ruined a front sub frame bushing.
