Cleaning 3rd member

You can flush the inside of that carrier out with anything you want to. You can use diesel or PB Blaster or hot soapy water and a pressure washer or whatever you want to and then blow it out with air and then spray a little PB Blaster in there or whatever to keep it lubed up a little.

Brake cleaner works great also.

Awesome! I like soap/water and pressure washer.

Here are the axles about to be cut. Then I'll go get the bearings pressed on as I don't have a press to do it myself .

Remember that the retainer plates need to go on before the bearings, so don't forget to take them with you.
 
You did a fine job cleaning up that ‘third member’.
Prior to installation a couple of things that I would do, just to have confidence that the diff is in good shape:
1) put a torque wrench on the end caps, pinion nut and adjuster stay bolts. Check them to the factory assembly spec for torque, they should not move.
2) use a dial indicator and check lash at the ring gear. Verify it is with in the factory limits,
3) use yellow gear paste ( the exact name escapes me at this senior moment) for contact pattern between the ring and pinion. Verify that the pattern looks as it should considering the age on the gears.
You had said that the gears spin freely, but unless you really know a lot about this particular unit, I would want to get as much information as possible prior to installing it. If it does have a groan or a whine, at least you know some of the key set up dimension.

Going to go get a dial indicator and some gear paste now
 
Well that sucked. No parts stores had either thing I needed. Maybe I'll Amazon it all.

Test fit everything anyways. :thumbsup:
Ps don't mind my mess, I try to be non messy but my mind is going a million miles an hour with 50 different things all the time and well things get messy.

Took the advice.

I went with the digital guage so there would be no guess work on the exact measurement.

Seems to be about .5-.8 all the way around, I think that's good looking at past threads.

I couldn't find compound so used a little acrylic paint my wife had for arts and crafts. Contact looks pretty good to me.

To measure the backlash you need to turn the gage 90 degrees and set it against the back of a tooth.
push the slack out then zero the gage and then wiggle the ring gear.

Set it differently than I have it? I thought this was how the guy did it on the Yukon gear and axle video

I was wiggling it though, it has that little spot of it moves just a touch of movement. I was getting .05-.08

you get an "A" for effort
the pattern looks fine, as mentioned, set the indicator to inches (thousands), you are wanting to measure the side to side movement of the ring gear, with zero being the ring gear fully pressed into the pinion. These inspections give you information on the relationship of the differential components, good down the road information ( and skills) to have.
 
Good job.

I hold the yoke to keep it from moving. Zero the gage then rock the ring gear.

Now put it in the car an run it.

Oh it is going to go in! Finishing cleaning the rear brakes and front brakes then I should be able to throw everything in. (8 3/4, 3rd member, disc fronts, rear drums etc)

Any A in my book is good for me! I don't get those often

That's me!!! Clinically/hands on though I'm top in my class (per grades in those classes) it's just the bullshit classes that I don't care about. Like who cares about the Krebs cycle? :rofl:
