Warn Hub Questions

I pulled the locking hubs off my Jeep last weekend to try to free them up and repack them. I have never done this before, but it seemed fairly straight forward. I was able to get them cleaned and freed up, but have a few problems. After I put them back on, the front tires pull fine in 4wd, but there is a popping sound when I turn or go from fwd to reverse.

Before I start explaining what I found, please bear with me if the terminology isn't correct. Like I said, I have never done this and don't know what some of the parts are called. I will try to explain the best I can. I don't know what model number or series I have. I can only say it is a 6 bolt manual Warn hub. On the inside there are two sets of gears. An internal gear that has a lock ring holding it and splines that fit over the axle shaft. The other gear is larger and rides between the housing and the smaller gear. There is a spring loaded plate that rides on four pins that go through the outer (larger) gear. The dial screws into this plate and moves it back and forth when you turn it.

When I tore them apart, there was some springs missing on the back of the 'plate'. This was only on the right side. The left side had springs on the both sides of the 'plate'. Aparently somebody has already gone in to them before and left parts out. I also found two washers on the right one, but none on the left one. This tells me they probably tore both sides down at the same time and mixed the washers up. I repacked the roller bearings and lubed everything up with grease before putting them back on. I am thinking the easiest thing for me to do at this time is to buy new hubs and replace them. The wheel bearings are also extremely loose allowing the axleshaft to be sloppy.

More questions:

1. Is there any good information on the internet to find out which model I have, a parts diagram, or instruction manuals?

2. Will it be okay to run like this until I can repair or replace?

3. Does this sound like factory installed or aftermarket hubs for my model Jeep?

4. Can the wheel bearings be tightened or do they need replacing? I am thinking I should be able to tighten the lock nut behind the hub and take some of the slop out of it.

5. The popping I am hearing sounds like a CV joint in front wheel drive cars. Would this be from the wheel bearing slop or the hub installed incorrectly? It didn't do it before I tore into the hubs.

6. Any other pointers that may help me out? (and I don't want to hear anything about me needing to learn more about what I am fooling with... :P That's what I am doing here!)
Thanks,

1) ???
2) Maybe not. I highly suspect its your axle joints making the popping noise due to improper or non existant end float control.
You will need to identify the type of axle shaft joint. Bendix Rzeppa or Spicer ?
3) Aftermarket
4) Jack the wheel off the ground, grab the tire at top and bottom Push in/out to test for adjustment.
A barely detectable amount of play is correct.
5) ???
6) Repair only one item or assembly at a time in order to observe definative results from your efforts.

Thanks guys.

Don - I tried the search and found the link you were referring to. This isn't what I have. Is this what you're telling me I should get? I was going to order a replacment set of new hubs, bolt them on, and forget about this topic. I hope it's that easy...

oldtime - I will try out find out what I have. I'm sure it will all start coming together as I tear into it deeper and try to find replacement parts.

In #2 - How do I find out the type of axle shaft joint? Info anywhere??
#4 - I did this and the slop is horrible. I know what it should be and this isn't it! Are you confirming that I can adjust the slop out of it by tightening the hub nut? I don't want to overtighten and smoke the bearing, but I would like to teighten it. I plan on pulling the bearings this weekend to see what shape they're in. If bad, I will replace. But if not that bad, I will try to tighten.
#6 - I always do this when I'm not sure and there are duplicate parts! The problem is, somebody else had been in these hubs before and things weren't the same on both sides. Which is correct...? :unsure:

I really need to get the manual! I apologize for the long posts and numerous questions. I am actually one of those people who have to see things for themselves and can usually figure it out, but when you have never seen those things before you need to know what you're looking at, right?!
Thanks,

# 4 Go See: http://www.film.queensu.ca/CJ3B/Tech/Steering.html

First solvent clean and visually inspect all 4 wheel bearings.
After installation... tighten the wheel bearings so that play is barely detectable.

# 6 Not sure what you have there.

That was my fault for giving an answer when I was in a hurry. There are several links in that post. The one I was thinking would help is.

http://www.jeep-trucks.com/index.php?page=...arn&action=WL-2

David Hoelzeman also has some info on the WA-1 also, just find that item at the top of the page above and click.

As far as the Warn web site,,, I could have sworn they had a better parts diagram posted at one time. What's there now isn't verey helpful. In the future I'll open all my saved links before I post them on the BB.

Here is a couple of links that'll show the parts in the hub.
