dana 30 spindle disassembly

I noticed that my wheel bearings were a little bit loose when I first got my Jeep. So, I decided to finally take a look at them. I jacked up the Jeep, removed the wheel and drum, then proceeded to take off the lock-out hub. I then removed the snap ring and the rest of the hub. Behind this were the wheel bearing retaining nuts. I'm used to just taking off the outer nut, lock washer, and then the second nut. Then you have access to the wheel bearing. However, in front of the two nuts is a steel (locking ring?) that is preventing me from removing the nuts. It has 5 or 6 small holes evenly spaced around it. Does this screw off some kind of way? (I assume it does). If so, where can I find the tool to do so? BTW, this is on a Dana 30 with drum brakes.

Sounds like you have either Warn Lock-o-matic or automatic hubs as they use the type of nut that you describe. Two of those five holes are for a spanner wrench. The other three holes are for allen head lock screws. Try sticking an allen wrench (I forget what size to use) in some of those holes and see if you can find set screws. The set screws are meant to mate with a lock washer that has corresponding holes.

Yep. The sticker on the dash of my Jeep said "Warn Lock-O-Matic hubs" and it says "automatic" on the hub itself. I'll try the allen wrench. Luckily we have a ton of them. If we don't have it, I'm sure my neighbor will. He's a farmer and has a whole drawer devoted to nothing but allen wrenches! Thanks guys. This saved me a lot of cussin' and sore toes. Not to mention sore tires for the Jeep. I'll keep ya'll posted.

Just a note regarding removal of those nuts. As I mentioned, two of the holes are designated for a spanner wrench used to tighten/loosen the nut but most people will hit it with a punch and hammer or something similar. Be careful when doing that as I've seen those nuts crack across the holes because of that.

I just tried the hammer and punch today, but as usual they didn't budge. Just like everything else on my Heep. So, I decided to build a removal tool out of some scrap exhaust tubing and welding rods. Well, that didn't go too well. My tool broke. So tomorrow I'm making another one that looks like the spanner wrench that you use on angle grinders for changing the wheels. I'm using nails instead of welding rods. I figured they'll hold up a bit better.

THe wrenches for these are relatively cheap. Go get one so you don't damage anything. External auto hubs are somewhat of a rarity these days and parts are just about impossible to find. If you don't like them or juast want to swap to a set of prmiums, list them on the binderplant forum. The IH guys love those things and gobble them up. Here is some great info on them.

I have a set of Warn Automatics and they've been relatively trouble free since I installed them in 81. Only real problem I've had with them is I bent the bolts slightly on one side. I guess they must have been a little loose. Got a new set of bolts and torqued them to 30 ft. lbs. and been good ever since.

wow thats interesting. once i loosened the allens i was able to remove the nut by hand. then again the bearings inside were completly destroyed so there wasnt much tension behind it.

Great news everyone! I finally got it off. It just took a bigger punch and a lot of hammering. My second tool failed as well. The idea was there, it was just poor materials. Oh well. Looks like I need new bearings and a seal though. I just re-packed the bearings and put it back together until I get all of the parts that I need. At least my wheel doesn't wobble anymore. Thanks everyone for your help. Here's a cold one on me:
