98 Trooper II rear axle. - Pirate4x4.Com : 4x4 and Off-Road Forum

A little info if someone can.
I picked up a 98 Trooper II rear axle today. I plan to use it in the rear of a stretched early CJ project.
What kind of pinion angle do I need to limit myself to. I cant find much info on the pinion oiling of these, although I hope at 100" (+ or -) wheelbase I won't have to much of an issue with that, but I would rather not have any surprises.
The other thing is, this axle is actually not the axle I was originally supposed to pickup.
When they pulled the other axle it was bent. This one has a few miles on it. Around 145K.
This axle has a little play in the gears. About a 1/4" of movement, at the driveshaft flange. Or the outside diameter of it rather.
I didn't have time to pull the hogs head and look it over real well this afternoon, but I will tomorrow morning.
I wanted to know how much slack was usuall, or to be avoided.
They did offer to give me the hogs head out of the lower mileage axle though, if I pulled this one and found reson for concern.
Thanks for any input, Andy

you should be fine............we have done set ups on axles with 200+K on them and bearings show very minimal wear.

hats off to you for an out of the box axle choice for you project.

i love hearing this.

Thanks for replying.
This axle was a no brainer really.
Disc brakes, 63" wms to wms, a set of Rodeo 44 gears, already on hand, that will go in the front. Cost was a plus too.
I've got a GM dana 44 that will be set up with 6 lug hubs on it. Chopped 4" off the long side, that should measure 63.5" wms to wms.
I believe this will work fine.

A few more questions if you don't mind.
Does anyone have a need for the rear two ABS sensors that were from the models that had them mounted at all 4 corners? I have the rear two from this axle.
I would love to trade the two sensors and the brackets with the holes for them, for two of the brackest off of the model that had the one ABS sensor in the carrier.
Also, how well does the LSD diffs that was optional in these axles hold up with 36"-38" tires? This will most likely be about a 3000 lbs vehicle. Has anyone here had a chance to find out?
I'll probably use the LSD diff for now, until funds let me buy an ARB locker for it, anyway.

I think you'll be ok with the rear LSD. The Wizard runs a 12 bolt (in a 4link) with 245s stock and they're around 4100lb curb weight, not to mention a WB of 108". I don't know how long things will last with 36-38s. I hear a lot of guys like to weld the rear and use the easy way to lock it. But don't know how long that lasts.

The LSD is a lot better than nothing. Like you said, use it meanwhile you save for an ARB.

That's if it still works at all. That many miles, I've rarely seen an LSD-equipped axle out there that still functions on the trail. On pavement/wet conditions, maybe. But in an offroad environment where wheels are going to be spinning a helluva lot more, I think your best bet is a Lockright or something now. It's cheap...

x2 on the unconventional axle comment that Matt made. That kicks ass.

Lockright (powertrax) doesn't offer a locker for any variation of the Isuzu 12 bolt at this time. The only aftermarket locker is from ARB. Welding is also an option with an open carrier... I'm not sure if that remains true with the LSD-equiped models or not. I can't imagine clutch packs welding all that well. 36" tires should be no sweat for that axle on such a light rig; but the engine torque and gearing reduction you plan to have has as much to do with that as anything.

But you can bolt a Toyota axle under the back and fit a lockright to that instead... Thats what I did in my Amigo...
