1. Beadlocks - I want them. What brands would you recommend or avoid?
-Trailready are nice beadlocks.
2. I will probably go to the 1 ton knuckles on the front axle which will change my bolt pattern to 5 on 5.5.
-Good choice.
a. Can I use spacers on the rear?
-you can use wheel spacers/adapters in the rear but they are notorious for coming loose, I don't trust them even with the locktite on so I don't drive it on the road more than a few miles anymore. adapters are like $99 a pair.
If so, I assume that will affect the width that the front axle needs to be built to - yes?
-Front width should be increased anyway to allow room for the spring plates. Mine is 2" wider than stock and still didn't have much room for the drivers side hardware. My drivers side axle tube is like 2" long because the 9" center is much wider than the stock one. You might ask Dave Kemner about what he would recommend for a width for the front end.
b. If not...can I get bolts put onto my existing axles in the 5 on 5.5 pattern? I ask because not only do I have the Dutchman shafts that are on the Jeep but I have a set of Currie spares too.
-you might want to check but on my rear 9" the axle shaft has the bolts on it and that cannot be changed without getting new shafts, and drilling new holes in the rotors to match.
3. I'm still deciding between the Currie axle and the Spidertrax axle. I know Erik Miller had had some issues with his Currie axle. Suggestions/opinions?
-Erik beats the hell out of his jeep in ways we will never truly understand. I personally would go with spidertrax but you might want to check prices too.
4. I was considering the Tru High 9 but Bill said there are some issues with them now.
-clarification: the issues are with the 9" high pinion setup in the rear of a vehicle due to poor lubrication with the pinion pointing up. there are also issues with the ARB RD99 locker that goes in both the currie and tru hi 9 differentials. due to it's unique design it is notorious for blowing seals and clutch gear failure (just ask the red bull team at the comps or look it up on pirate) tru hi 9 is much stronger than currie hands down but is very expensive. Now having said that I've beat the snot out of my front axle that has the currie 3rd member and has the RD99 ARB that is problematic and it works great. the rear one is having the problems.
I plan on having Dave at Full Circle do the work and once I have some input from you guys I will talk to him and see if he has any other ideas.
-Dave has a wealth of knowledge so ask him what he would do and get ready to pay out the wazoo. a good custom built axle like mine in the front will cost about $6000
You do have another option. just buy a D60 and call it done.
