I just now had a chance to get back and read all u had written.thx everyone for the input.They all pretty useful altough I always carry all kinds of lubricants/oils, water,more then basic tools,rec. gear etc.../ but the oil filter is really a good idea and I probably would have never tought about it until I needed one on the trail./the only protection I have for it is the factory plate/.
The cv is also a good idea/just got the boots done/.I would be crying if my weeling would end because of it.So I will deffenitely get one as well as the spare belts/unfortunately thruw out the old ones 20k ago when it was replaced/.I am kind of puzzled by the spare rear drive shaft/pretty big piece and heavy. kind of/.Will I hear any sings before it goes bad or it only takes a bad moment?
But the best help would defenitely be the group of similar vehicle owners with a lot of knowledge.So thx for the help and I hope to see/meet/ most of you on the Zuu-Zuu in may.

I assisted in a repair this weekend on Rubicon -- a guy had holed his oil pan, and was capturing the oil when we encountered him. I gave him props for being environmentally friendly, but that proved to be necessary, as well, since he lacked more than about a quart of bottled oil. He did have a few quarts of gear oil, but with the captured spilled oil, the most-of-a-quart of new oil, and about a quart of gear oil to get to the low point on the dipstick, he was good to go after the repair... which underlines why I like to pack a full oil change worth of motor, tranny, and diff oil (some may overlap, and simultaneous failure of all is unlikely, so some balance for weight/space/need is necessary).

I rank spares by necessity of repair... engine is critical, transmission less so (as long as it can turn in at least one speed), axles even less so (as long as at least some motion can be maintained), and so on.

Several tubes of gasket maker and brake cleaner saved the day for the guy on the trail -- having a propane torch to light damp wood to fire allowed a campfire which made waiting for the silicone to dry that much more tolerable!
