Locker abuse
Well, I've had my front ARB a few weeks now. Yesterday, I actually
needed it for the first time. I was climbing a steep rock hill. And so, naturally, I just busted my first front axle U-joint. I bought a H-D replacement - but hopefully this won't make some more expensive part the weak link. I'm looking for advice on the replacement job. This is for an '85 CJ-7 Dana 30 - passenger's side. Are there any gotcha's out there? Does anyone know any special tricks that would help me out? Do I also need to replace any seals or gaskets while I'm at it? One thing that has me worried is the metal "ring" at the outer end of the axle tube. I guess it's just a pressed in seal or guide. It's been knocked loose by the wobbling axle shaft. Does it press in place? Is it just a splash seal? I don't see this part on the exploded views in the books or catalogs I have. I did a Google search and found a couple of posts by Jeff Strickland that make the job sound pretty straight forward. He says "Remove the hub locks. Remove the brake rotors. Remove the large spindle nuts from inside the spindles and pull the hubs off. Remove 6 nuts holding the dust shield on and remove the shield. Use a large rubber mallet, or a board and a hammer to nudge the spindles off. Slide the axle shafts out and replace the UJoints. Assemble in reverse order. Torque the inner spindle nut to 80 pounds and spin the tire around several times and re-torque. Repeat until you are confident the spindles are tight. Torque the outer spindle nut to 50 pounds. DON'T FORGET the washer between these two nuts, and DON'T FORGET to bend one side over so it will hold the outside spindle nut.; This washer is really a cleverly disguised locking device; use it. Torque the dust shield nuts to 50 pounds." Is there anything else I need to know? And yes, I still made it up the rock face, and back out through some right slick and tricky stuff in 3-wheel drive.

Re: Locker abuse
The seals are inboard at the pumpkin. You have to be clean and careful
putting the axles back in. I use a sacrificial bolt and alternate cutting the steering side to side so I can beat the crap out of it as I move it around the holes to remove the spindle by pounding with a BFG, preferable 5 lb. They can be an SOB to come off first time. I hate those 'heavy duty' U-joints, they didn't last 8 months for me because they can't be greased so got water contamination.

Re: Locker abuse
Go directly to http://www.stu-offroad.com/index.shtml then click on
Index of Mods & Writeups, then click on "Axleshaft U-Joint Replacement". There is no better single source of Jeep help than Stu's website. The only additional thing I can suggest is replacing your D30's axleshafts with hardened axleshafts like the chromolly 4340 axleshafts from Warn, Alloy USA, or Superior Axle. Those are what will do more to prevent u-joint failures than anything else other than going to some uber-strong/expensive u-joint like CTM makes. These axleshafts have heat-treated hardened ears that hang onto the u-joints FAR more securly under stress so they don't break free and then break, taking everything with it. What few people understand is that it's more likely that the axleshaft ears have let go of the u-joint which caused the failure, than the u-joint itself failing first which is extremely rare.
