DUDE! whatever you decide to do drive over to La Mesa (my house) and we will put it together for free. I think the #1 thing you need to do is stop going to shops. As for a steering stabilizers they are only band aides. A properly set up front end, you won't even need one. If you wanna spend 50+ bucks on a steering stabalizer get a Rancho 5000. If your shock is stock then yeah I say get one, if it's not and its an aftermarket, take it off, collapse and extend it to make sure it's good. If it is, throw it on and forget about it. Worry about the other stuff.
The crappier it drives on the road the better it performs off road!
Get your jeep over here some time for about a 1/2 day and we'll go through it . Im off the 8 and Spring St
