First off, a big thanks to Cruiserdan for the birf rebuild parts. Especially after UPS tore the box and lost 2 of the trunion bearings. He sent replacements ASAP and got me on my way.

Now a question. I seated the inner axle seal on one side, and afterwards I noticed that the little ring that looks like a spring had come off of the inside of the seal. There is certainly no way for me to get this back on to the seal without taking it out, which will result in certain destruction. I can only assume that this is a necessary part of the seal, but I'm looking for an absolute "you need to replace it" before I run around town looking for one. If that is the case can anyone verify the part number? I'm at work and forgot to write it down and bring it with me.

Thanks!
 
I think you must replace it, it is what presses the seal to the shaft, I don't think it will be a seal otherwise.
 
Part number 90310-35010
 
replace, sounds like the outer ring deformed when you seated it and popped the spring out.

I have begun ordering those damn seals in 4s to cover my since I usually hose them up when I replace them :)
 
I'm with Rookie on this. It's actually pretty darn hard to dislodge just by putting it in - I'm betting you are looking at the one that fell off the seal you took out. Anyone got a picture of one so he will know what to feel for on the back of the seal with his fingers? Or anyone know if the spring is magnetic so he can use a magnet to see if he can feel it back there?

Unless you're pretty darn sure you knocked it off (I've rarely heard of this, and ONLY from inserting the axle clumsily) you should spend a few minutes establishing if you're mistaken. Also, don't use a non Toyota part here - very bad experience over the years. I'd sooner pay $20 to FedEx one than do that.

PS I'm in Coeur d'Alene and may have one if it's an emergency for overnighting.
 
I'm pretty certain. I'll have to double check, but I'm pretty sure I just hit it wrong on one edge with the block of wood I was using to seat it. That should teach me to be a bit more careful next time!
 
The guys are making a pretty good point, when I did my birf job on my 93, I put the seal in, and was afraid I had dislodged the spring in the process and thought I couldn't feel it, but after rechecking and carefully feeling it, the spring was still there...FWIW
 
Just checked on my spare. The spring IS magnetic and a small kid's toy magnet held inside the seal easily indicates there's metal in there. So try it on yours. I also would not rate re-installing the spring as impossible. If someone comes up with a picture, you'll see it goes just inside the lip and I could see you hooking it up top, then running your finger around and pushing the rest inside easily. Kind of like putting a tire on a bike rim. Unless the spring's broken, but that again leads me to believe it's from the old seal. Anyhow, that should help ya...

Thanks, all! I actually tried putting the ring on one of the old seals I had pulled to see if it was possible to reseat it and I couldn't even manage it that way. I determined that doing it backwards without being able to see it was more trouble than I was willing to go through!

I just talked with the local dealer and they have a couple in stock, so I'll pick a new one up just to be sure. But I'll look to make sure that I wasn't just looking at the old one. After that much time working on the thing, I wouldn't be surprised if I made that mistake.

Thanks again!
 
Installing that seal is a PITA, I finally designed a custom driver, and had my son spin it out for me out of hard maple on his nice wood lathe:

The long "snout" on the driver fits into the ring inside the housing, acts as a guide. Works excellent, never had it fail to get the seal perfectly driven with only 1 or 2 smacks with a deadblow mallet.

Unfortunately, 80's are larger, so I had to make another one for doing earlier Cruisers and mini-trucks.
 
Cool. Seems like at least one person found one laying there from previous owners.

A short update:

I pulled the seal out and the spring had dislodged. I have a special talent for breaking things, it seems!

Anyway, thanks to all for the advice and to Doug for the offer of assistance. I got a new one from the dealer and installed it last night. I sure hope I can finally wrap up this project this evening!
 
Since you're prone to this stuff, be very gentle when reinstalling the axle shaft so you don't knock the metal guide ring loose. You can see it in there, and banging the end of the axle against it, even gently, is like hitting it with a slide hammer. Similarly be gentle sliding the axle through the seal. I coat the axle with grease lightly beforehand.

I don't know whats with all this wood stuff. harbor freight has a replacement set for less than $20 bucks that works fine.

Yup, I have one of those sets, actually mine is a nice Lisle set. It's a PITA to use in this seal though. Kinda hard to hold the seal in front of the tool, inside the cavity of the knuckle. Mine is very easy to use, slide the new seal on, stick it in the hole, couple of smacks with a mallet, all done.

nakman, thanks for the compliments. I begged my son to spin out a bunch of them now that he has the pattern, I figured he could sell themon MUD. He's too busy with other stuff.
