That’s what it takes to get the perfect tolerance in a diff. I’ve built hundreds of them and my tolerance and the factory tolerance were much different. When set up correctly a diff will last a long time. I only ever had one bearing on a Dana 35 that the inner race was out of round.

A tip for getting the broke bolt out of the center pin ..take a small mini screwdriver that has a magnet in the top,like the sales reps give away...take a shrink wrap tube ,put the magnet in the tube ,heat shrink wrap on both sides of the magnet ,trim top edge as close to magnet as possible,,,,clean hole good with brake clean &, blow dry with air hose..(watch you're eyes!)..happy fishing..it will slide perfect into the hole,dont have to worry about loosei g magnet in hole,& as long as the magnet is strong enough it will stick to bolt & turn it ,dont force it ,stay calm & it will come out..

Luckily I never met most people. I was taught on stock cars, shimming and lash were the biggest part of the process. Pretty much everything else was just going through motions.

@@chestervaldes7551 It's not a terrible idea to clean things out and if you have an axle seal fail, it would be more important. But it's really not that critical, especially if the axle seals are in good shape and weren't leaking.

Doesn't look like the first time you manhandled a rear end with one hand. 😂

[@fascistpedant758]

I like to get both hands on them!

[@ironpanther2420]

Personally, I'd let this guy manhandle my rear end anytime. He knows his stuff!

The way you installed the snap ring went against everything I was ever taught or read on the matter of snap ring installation. Was that how the manufactory said to install it?

[@MemyselfandI001]

Yeah. I believe it's backwards also.

[@22099dscott]

I was told decades ago that the groove that the snap ring goes into is what determines which way to install it. Some snap ring grooves have a square edge, some have rounded edge at base of groove. You try to match the surfaces.

[@bovineknievel410]

He installed it correctly for this application. The sharp edge should not be pushed against anything. The round edge should take the load.

[@chrisrogers1833]

@@bovineknievel410 - Exactly. Another poster found this wikipedia entry with a diagram: en.wikipedia.org/wiki/Circlip

[@rtta51]

I was taught that you want the flat side facing you so that the snap ring pliers get a better bite on the sharper edge and won't slip out when removing the ring. Learned something new.

You didn't need to remove that for one thou. What you should have done was remove the pattern paint and checked again. Once dry it can take up a thousand. And believe me it will. I've rebuilt thousands of rear ends. You did a good job kid.

I used to rebuild lots of differential units in cars, trucks and large wheel loaders as a fleet mechanic for a Rock Quarry many years ago in NZ. We did all our engine, transmission and differential rebuilds in-house in the quarry workshop. I always used bearing blue to wipe on crown wheel to check contact pattern and put a wedge on the back of the crown wheel to create lots of drag when turning the pinion to get a good crown wheel tooth marking. Sometimes it was a bit of trial and error work to get the pinion shims right to get a correct depth/mesh pattern. If the mesh pattern is incorrect it will cause a wine in and a possible failure due the the load not spread evenly on the teeth. 🚜🚗🚛

Just curious about how you said the "C" clip went in, rounded side out. I've been putting "C" clips in with the flat side out. Hum. different strokes I guess.

[@billpeasley]

Round side should face in and sharp side faces out.

[@harrystone8847]

According to Wikipedia, the orientation is determined by the direction of force on the c clip. en.wikipedia.org/wiki/Circlip

[@chrisrogers1833]

@@harrystone8847 - Nice link. Had no idea the channels had radiused machining. So rounded side out is correct in this case.

[@chieft3357]

@@harrystone8847 Sorry for not responding sooner but been busy. You are correct, direction of force determines position. As with axles in a differential, the flat side of the clip goes to the outside, away from the axle end. It's how a mechanic would look at it.

[@alanclark639]

What a fine chip off the old block you are Son! Not only did you get skills from ya Pa but also a good helping of patience! Dogged determination will always win. Great that you can be this conscientious and make a living - I know some wonderful craftsman that work away in sheds on virtual vanity projects - vintage steam engines for instance but their premium turnout is undervalued.

[@rodneymiddleton9624]

I've even had to grind the end of the cross pin to get to the locking pin before. That set up must have been Chinese steel. LOL!!! At least you are pitting in the finest "Made in Taiwan" parts. The shame is it's hard to find "Made in the USA" stuff anymore. Great job and attention to detail.

[@RickC_]

Awesome - I did some gear work for US Navy generator sets back in the 80's Nice to see someone who knows what they are doing. Measuring backlash and torqueing crush sleeves is why I did the rear end on my truck myself.

[@stevetalbert2727]

The square side of the snap ring always faces out away from the load.You did a good job on your repair with a junk carrier but i hope you never rebuild a Hydraulic cylinder with a snap ring that retains the gland.

[@bovineknievel410]

No. He is correct.. The sharp edge of the ring will ride in the radius of the groove in the carrier as the ring is pushed outward if he installed it the other way. Sharp edge in a radius is a problem. Hope you never work on aircraft.

[@steved5518]

From an engineering perspective, what is the rationale for having a square side and a rounded side? Obviously the manufacturer specifies the square side on one side or the other. If it doesn't matter, it seems like a huge production waste of money for the clip manufacturer to take the extra step to round one side off. .

[@brucejones2354]

@@steved5518, in the stamping process one side of the part will have a rounded edge and the other side will have a sharp edge. These parts are usually put into a tumbler to take the sharp edges off before the heat treatment. Understand that time is money in a mass production business. It is a rare occurrence that any machining is done, mostly in aircraft or military conditions.
