yes, I searched...

So I'm going to try the fix listed in the FAQ regarding rear-suspension noise (my brake cable was taken care of under warranty a while ago). It mentions waterproof grease - does it matter which brand?

I see:

Closest thing I could find at autozone find was some lithium grease, but maybe the employee and I are blind (he hadn't heard of something like the products in the urls above). I'm guessing lithium grease won't cut it.

Anyone have experience with this? Recommendations?
