What do you all recommend for general maintenance chassis/suspension lubrication?
I am looking for something that will alleviate some of the squeeks I am getting with my suspension components and such. Aside from new bushings, is a White Lithium grease a good all around lubricant/protectant/anti corrosion substance? or would just plain Silicone spray suffice?

I am beginning to think about getting my car ready for winter again and aside from the annual visit to the undercoating shop, I am just wondering if there is anything else I can apply that will help extend the life of my undercarriage and chassis in general.

Thanks!
