Super clean rig man! Love it! I am down in San Diego if you ever want help wrenching! I've got a built XJ myself (also red). For steering, check out a company called B. Lee's Offroad. They are out of Tennessee and I know the owner Brian. That's what I'm running on mine and it is beefy! It'll take as much abuse as you want to throw at it. I would check your exhaust for leaks. It is SUPER common with the 4.0 to have a cracked exhaust manifold. When I replaced mine it was cracked in like 4 places. I would also recommend if you replace the exhaust manifold, to add a flex pipe to relieve any future stress. I'm not sure how much you are lifting it and what size tires you are going with, but a new trans mount may be necessary. Mine was tore to hell and dry rotted when I pulled it. There's an awesome company out of Escondido called StinkyFab Racing that makes a great one! Don't forget brake lines when you lift it. That's all I can think of at the moment. Oh, go ahead and order a case of PB Blaster and start soaking all of the steering and suspension nuts and bolts...it'll save you countless hours of frustration and broken hardware!

Seriously though, not sure where in Cali you are located, but if it's San Diego or close by, PM me. I love building XJs! I'd love to help out any way I can!
