The links to birf info were helpful. I know guys have asked for pics, do we have an ih8mud faq I can contribute to?

I didn't read an easy way to get the inner seal out, but this worked for me: With a drift distort the seal on one edge, carefully. Pry it out on the opposite edge easily.

That tapered drift also saved me from losing the snap ring, I stuck it in the threaded hole on the axle end so the snap ring couldn't fly across the garage.

Great drift for the knuckle races. It's the smallest of three in a $15 set I picked up at Sears. I can't make them at the machine shop that cheap, even without the knurling and chamfering. It fits the cutouts for this purpose perfectly.

I drove in the wheel bearing races and seals with big sockets. Here's the 2-1/8" that fits the wheel nut. I greased the hub before driving in the race, then degreased with brake cleaner to get out any shavings generated. I push a lot of bushings and bearings at work, tight fits like that often generate shavings. I also chipped a little chrome off my sockets. Thats what I use my 3/4" and 1" drive sockets for the most, pressing in big stuff.

You cheated...IIRC, the T-type seal puller ($10 at Autozone) was the recommended method for getting the axle and wheel bearing seals out.

Any reason why you seperated the hub and disc assembly?

The best bearing packer ever, a ziplock sandwich bag. Freezer bags are a little stiff.

What the heck's in the tub to the left of your baggie? A box of eels??

Stuff that oozed from the birf. My cat brought me a dead mouse during the operation, it was more pleasant. I epoxied the floor in preparation, it was nice not having to clean all that goo off cement.

Thanks for the phone help bro!

A T-type seal puller would have made your life much easier with that axle seal for $10 ;) . Also, IMO if you separate the hub/disk assy you need to have them turned together to make sure they are centered.

Good idea w/ the socket (hope it was craftsman!) - I used the "upside down" old race and a drift once it was too far down.

Nice to be done eh?

FSM shows marking the hub & disk for reassembly. New disk on one side, seems to be balanced still.

Err, rears to go, then start on my truck. I'll pick away at it over the summer.

Did the same job last week with new rotors, used the same brass drift set from Sears. Messy job, but not hard. I used the T-type seal puller with some success. Good job with the pics!
 
I've seen a few seal pullers, I'm not sure what the T-type puller is. From my research it sounded like everyone had trouble with that seal, so I assumed the pullers weren't working out. I got a grip on it with the prybar, but it wouldn't budge 'till I deformed the seal. Anyway, I wouldn't post solutions that involved specialty tools. I'll probably haul an arbor press home next time, not a helpful hint for most guys.

I'm still wondering what pics are still needed for a faq, and where to submit them.
 
Scott,
As I recall, we need some pics of the tools. You have one of the hub socket (the fancy Sears one.) I am almost positive we *had* a pic of the T-type seal puller but it wasn't with the FAQ. A pic of the Harbor Freight spring scale would be nice to have along with the 3 brass drifts lined up with something to give the tools scale.

That's all I can think of now but review Jim's post in the Tech section for a complete list of tools.

there is a Harbor freight scale shown on their site, the skinny one is 55lbs and $4 (they have a bigger one around that's 50 lbs). 55 lbs may be too much to do preloads (about 10) perhaps, though ?

added: going by memory it looks very similar to Marlin Crawler's so maybe would work OK anyway?

In my Fj80, the pinion seal is on the back of the third member and theres a small metal ring that goes around where the seal is. Should I just grab a crow bar and pry it out or what?

My philosophy was, if I have a new one, go ahead and destroy the old one getting it out. My only other oil seal was on the back of the hub you see on the floor as I drive in a new race. Posts and links I read indicated getting under it with a screwdriver or two and working around loosening it. That seemed to work well.
 
Ah, I'll be making a trip to the dealer to get that part, then out comes my friend mr. crow bar......
