Leaking 3rd member, blown out bushings, ground birf... How Fun!

I am going to button it back up in the meantime but order a new...
Breather (ARB kit)

For $10, well maybe $20 now, you can buy a length of fuel line and and cheap fuel filter and make your own extended axle breather instead of buying the overpriced ARB kit.
 
Well, the good news of the day is that the knuckle is still tapped with m12-1.50 so new studs are being ordered to reinstall. Do not need a new knuckle which is a plus. Full tear-down time, will keep yall posted on progress. Ty for the input gents!

Ordering...

ARB breather kit
3 quarts of 80w-90 gear oil
3x 1lb tub STP moly-ep grease
 
Weird, I just pulled it off and laid it on my chest. Putting it back I just rolled it off my chest into my hand and basically rested my elbow on the ground while i put it back on.

You aren't wrong, its kinda heavy but I suppose I never really thought about it.


Trunion bearings sit on the king pin...thats what makes it a king pin....just like the venerable Dana 60 King pins....
Your a real Man
When I pulled mine it was more like controlled dissent. Tell it hit the floor.😂🤣 Luckily, I had two layers of cardboard down there.
 
I second Cruiser outfitters for your parts needs
Knowledgeable sales staff, competitive pricing and super fast shipping.

On the differential gasket, you my want to consider OEM. Verify what you get but that looks like a cheap paper gasket in which case I would also use a Permatex Form-a-gasket.

The OEM gasket is metal that's sandwiched between two paper layers.

LOL, I think I just got lucky that my forearm was long enough to match the height of the axle off the floor.

I propably just a whoosy. 😉 But I'll tell you what, having a couple hernias repaired over the last few years makes me re-think the brute force and ingnorance path.:grinpimp:

as far as that video states if you don't mess with it, should stay set correctly...

That video is a pretty decent guide for a backyard garage dude.

IMNSHO he goes wrong at 55:30 mark when preloading the wheel bearings, backing off the nut, and torquing to 4lbs.
He says " we're gonna go by feel", but doesn't say what your feeling for. So leaves it at 4lb.

You can't feel preload on the bearings anyway! The first step where he torqued the hub nut to 45lb, then rotated the hub, it rotated just s freely as it does with 4lb torque.

In my experience, those wheel bearings will be loose after 2-3000 miles.

Where he retorques to 4lb, torque to 20-30 lb. 20lb for stock size tires, 30lb for 33"s or bigger.

Then fit your star tab washer, and 2nd nut. Torque second nut to 45lb. Lock/ bend the tabs in both directions ( in and out)

Fantastic, noted! Thank you
 
I'll throw my 2 cents in as I didn't see some of this mentsioned directly.
Inside the green bracket is totaly normal. While there is a "seal" in this area with a wiper, its a total loss lubrication system. Its supposed to be wet and greasy here. That's a good thing. Just top it off every oil change with some Moly grease through the cap in the top of the knuckle. I typically use aournd 35CC per cycle.

the Red circled area is bad and has been addressed adnausium. You need to get this fixed.

Other side:

The area circled in red is dry; this is bad. You can see the level of grease in the knuckle by observing were the wet line is between the red circled area and the green circled area. You will need to add EP moly grease through the plug, circled in blue. Based on prior expirance, propably 140mL (cc) or (4.5 oz) to start. Drive it around for a few weeks and see where the grease line is on the ball. I use a meat marenade injector to add the grease, that's how I know how much I put in. On this side you could probably put half a tube (7oz) or half a tub in there to start.

As noted by others, this side has the proper hearware.
is this a viable substitute?
 
The type of grease required is listed in the FSM.
Yes, it will work as its a NLGI Li soap base with added Moly.

Thanks, guys! The support is much appreciated! Parts coming in by Wednesday, tear down this weekend. She'll be sitting until then.
 
Best way to check breather?
Yes.
A breather consists of basically 3 parts; 1 cap, 1 spring, and 'the rest'.
You're looking for free travel of the cap on the spring, both down and up, under pressure and vacuum. Relative to 'the rest' of which it is connected.

Also ensure the associated hose and axle-mount connector is free and clear.

Compared to a class-8 (heavy duty) third member, the 80's (light duty) third is practically featherweight and one arm-able.
 
Okay gents, please weigh in. Pulled the passenger axle out, in two pieces. separation at the birf, looks like the snap ring is a little loose. Is this normal?

The passenger side is my problem side. Pics attached are of the top of the housing, showing gouging on the axle bell and the top of the housing. Is a new axle a good precaution? Or would all new bearings get it riding right and shouldn't have this be an issue?

Thanks!

Look like you might be O.K.
The birf can cleaned up with a file on the outer edge to remove any pieces that are loose or will easily fall away.
The knuckle: the abraded area doesn't look like it penetrated the bearing seat surface. If that's the case, just press in new bearings and rebuild as normal. If the bearing seat area was chewed away, you'll probably want a new axel.
The other thing to look at is the ABS sensor and ring. With the birf pushed off center, the censor ring may have chewed on the ABS sensor ring.
