ARB install

[Montoya]

Hi guys,
I have a couple of quick questions about an ARB install into the HP Dana 44.

1) I didn't use an axle spreader to remove the factory diff but it did require some persuasion with a crowbar. Do I need one for the install or have others gotten away without it? I know for a Dana 60 it's basically a must.

2) Where in Socal can someone rent a good pinion depth tool (and for that matter an axle spreader if I need it)? With the shims going under the bearing race, I really don't want to put this together and take it apart a ton of times to get it right. I machined the outside of the old race so I don't have to press it in every time but still a PITA.

I've got the tools for it. Pm your number and we can work something out. I've got front and rear arb's I want to put in my 72. I'm up near rosecrans and aviation.

Set up bearings are a lifesaver, make your own, takes maybe 15 minutes. Use your old bearings. You do not need a case spreader, least I didn't. I used a depth micrometer to measure pinion depth. Have fun, it is a ton of work, but nothing beats doing it yourself!

If you do not use a case spreader you need to at least use some wood wedges hammered in..a trick I used "back in the day". It is NOT a good idea to install only enough shims that the carrier slips easily back in to the housing.

I have the spreader, depth tool, bearing puller. I don't have set up bearings yet but I have old carriers with the bearings still on. What's the easiest way and how far do you grind em out?

 

[Brent13]

I mounted a grinding stone in my drill, move in a circular pattern. Then check fit on the carrier. Keep going until these just slip on. I quench in cold water after each grind, and before fit-test

My carrier was a bitch to get in and out when I got to my correct shim stacks! I had to pound in with a dead blow hammer.

The case spreader is absolutely worth the effort. I've done it with and without... and I'll never do another Dana style axle without one. It'll be real hard to get an appropriate amount of carrier bearin. Preload without it and avoid mangling your shins when you assemble it.

Do a search on pirate- there are lots of plans for making one out of about $30 worth of steel and grade 5 threaded rod.

Thanks for all the advice.

Totally going to take SteveL up on the renting of tools. 4wheel parts wouldn't rent the tools and wanted a fortune when I've got it almost all done.

I machined some setup carrier bearings but then when I got my ARB I found they are different from what is used in the ARB so if anyone needs or wants these they are available. They slide in nice and tight on the diff... Total pain to chuck up and machine but they work well. The setup race should make setting the pinion easy also with the right tool anyway.
