I work with high precision steel all day and know how to read and indicator. I've known of quite a few people that have set up a diff. and it can't be that hard. Any idea as to where to find instructions or any helpful tips?

i installed my front ARB and haven't had any issues. mine came with a pretty good set of instructions when i bought it. if it was in the rear i might have second guessed myself on installing it, but now that i have installed one i would do a rear. just read the instructions, pull the cover re-read all the instructions, pull the carrier bolts, re-read all the instructions, pull the carrier, re-read all the instructions, get the point yet? just be sure to read and understand all the instructions.
 
D30 front, D44 rear.

I figure I've built a few engines in my time that have held together, what could be that difficult about a solid axel.

Use the same shims as the existing carrier uses. Check the backlash. If it's in spec then you are good to go, if not then you need to work on your shims. You'll need set up bearings for that. Set up bearings are reamed out a little so that they are easy on and off for changing shims.
 
Thanks for the info! I'm going to take my time doing this, so maybe I'll just add new bearings and take a few thou off my existing ones.


Thanks again,
Ryan
 
You'll need new bearings. You usually ruin the bearings or the shim packs getting them off the carrier. The original ones will work fine for setup bearings, but the cages will be too tweaked to trust long-term.

Some carriers have notches milled behind the bearings where a 2-jaw puller can reach the cone, but most don't.'

Make sure you get plenty of preload on the carrier. Insufficient preload is the #1 cause of leaking ARBs.
 
The little brass tube is my biggest concern with ARBs. I never liked having to be careful around that tube. Makes installation a 2 man job if the axle is in the vehicle. But then the OX locker is no picnic either. Go for the case spreader if you can find one. Its easier than beating the shims in.
