Re: ticking noise
broken exhaust manifold bolts... WAY common... get some new hardware, a manifold gasket, and order up a round or 100 of patience along with some beer for when the patience doesn't work and get-her-done!
The drivers side is the best one on the WJ becasue the collector hardware on the passanger side is a DIRTY dirty whore... The drivers side they are decently open, not to mention there is also a bunch more stuff in the way on the passanger side, you can also unbolt your intermediate shaft from the steering gear and give yourself more room on the manifold.
