Ok showing my ignorance here but...

I was just wondering if anyone has any good links to some detailed diagrams and/or pictures of the unmodified JK suspension/driveline system. Post 2007 if possible. I Googled a bunch of word search combinations but came up pretty dry actually.

I'd like to learn a little bit about how it works and what all the parts actually do and how they work together as a unit. I figure the more I know about it the less money I'll spend unnecessarily. Since I'm not mechanically inclined, I always find talking to mechanics a bit of a cat and mouse game. They seem to spot a lay person a mile away and then charge accordingly... :shaking:

I know I can't really learn about a topic by looking at pictures alone but it's a starting point and as they say, a picture is worth a thousand words. As soon as I have a real space to work in (like a garage), I plan on doing some repairs and modifications myself. Can't do that now.

Anyway, just being lazy until I can get my hands on a real book... :)

I admire the fact that you're willing to ask for help. :)
Try searching the web for "4 link suspension systems", "4 link calculators", "4 link with track bar", "4 link with panhard bar"

You will probably come across some car applications and diagrams in your search, but the JK uses a simple 4-link with track bar, which is found in many applications.
The 4-link Calculator (Excel File) may be a little overwhelming at first, but it's fun to play around with it when you understand how it works. You will be able to see the effects that changing angles and arm lengths have on the overall system. :beer:
