Dana/Spicer 70 and 80 axle info

Front and rear light axle parts, kits and applications. Chevrolet 70 and 80 extract attached.

Good information and very timely for me. I have a 1992 Landyacht 36' with TAG axle built on a Chevy P30 chassis. Curious as to how to tell what rear end is installed on my coach. I have the rear disc brake option if that's critical. Planning on doing a complete rear brake overhaul this spring including:

New rebuilt calipers
New Wagner Thermal Quiet pads
New rotors
New wheel bearings and seals
New wheel studs

Need to know what axle I have in order to order the some components. Since it's a 1992, I'm not sure if it's a Dana 70 or Dana 80.

Also, any suggestions on any additions to the list or things to watch out for would be greatly appreciated.

Not trying to thread hijack but it seems relative to the posting.

I'm no expert on the rear axle, but you can probably work out what you have by looking on Airstream.com on the document archive https://www.airstream.com/wp-content...ations-489.pdf
and cross ref with the Chevy/GM manuals for the year. You can probably get a manual which is very close here: http://67-72chevytrucks.com/vboard/s...d.php?t=545416

Obviously, will not include the tag which I assume was an Airstream add-on.

A Compnine report or more expensive GM report will likely reveal your RPO codes. if you have these codes, you can decipher them and work out which factory GM axle was installed.....at least I think you can.

We did that job on my 92 350 just recently and I replaced parts by pulling the old ones, like the inner and outer bearings. Everything else appears to be P30 specific spanning over many years. The most important thing to follow strict procedures on is setting the wheel bearing play. I can take a picture of the torques and tool required, if you dont have it.

Any pictures would be a big help. I have the 4 tab special tool needed to remove the spindle nuts but could use confirmation on torque specs. Seems like it's the only "special" tool needed.

One question though... How difficult was it to remove and reinstall the axles? Wish GM designed it so the rotors could be replaced without having to remove the axles but so be it.

Just pull. Comes right out, easiest part of the job. It's the rotor/bearings assembly that's a bear, because its heavy.

Everything is pretty easy except the small outer bearings (hard to reach, I left mine alone), and the big inner bearing race (large press fit part)

sorry Nick for going somewhat off topic, but not really

Here are the specs for the rear bearing adjustments
