I've installed 3 diff bushings so far. 2 SPL's and 1 Z1. The SPL's were easier to install. They're a solid bushing, where the Z1 is poly. The poly moves around during installation. The poly transmits less vibrations.

Alright so yeah - Silicone leaked down my Diff - thought it was diff fluid.

So Rusty - which bushing do you suggest? If install isn't an issue?
