This was very helpfull ThankYOU I am doing a 12bolt rear for a1970 Formula 400 ;-) I never did one of these and it needs to get done cause its screaming. lol The video was very clear and easy to understand. And one fellow in the comments gave a good tip called carrier bearing preload. which seems like a very invaluable tip. Thank you all
I like the video, I have been building rear diffs professionally for over 25 years. 2 things that are missing. 1st once you have your backlash correct, you need to add a little more shim to both sides of your carrier. This is called carrier bearing preload. Without this preload you carrier will get loose as the bearings break in. Same reason you have pinion preload. If that diff ever gets noisy, this is why. Once it does you will need to start over with new gears. I would say you need an additional 10-15 thousandths total. So half of that per side. 2- the side of the tooth I saw with the marking compound was the coast side, I couldn’t see the drive side.
When doing the preload on the pinion and career bearings, is it a good idea to do the checks with lightly oiled bearing or just set up with dry bearings?
Hey. I have a question. I took a part a 1971 Olds cutlass rear end to replace the bearings I needed mark the bearing caps need to know how I can know I put the right one on the right bearing and if there are on up side down or right. They have arrow on the caps do the arrows point to the axle or toward the 3rd member.
I’m building a 12 bolt, I didn’t use crush sleeve, I used a spacer and shims, what I’ve read pinion preload should be @25ip? Video was informative though

Hello sir, after watching several videos of setting up the pinion gear-carrier group, your video is the Best straight forward video! Great job
Thanks. Appreciate it.

Thanks for the info. I’ll double check

You made sense to me who has never done that before... Thank you 👍
i did my posi 3 years ago, ive got side to side play now, im going to add some shims. thanks for the video, a little more volume would be great
Thanks for the Video, I need to swap out my .411 gears for something hwy friendly..
Where did you purchase the pinion depth tool
Summit
Great tutorial! Thank you.
Crush sleeve is such a pain. Spacer is way easier
Thanks man. Great video
Thanks

Very helpful thanks
Glad it helped

Thanks. I used what I had and I was unaware of spacers when I did it. Crush sleeve is what I’ve always done. 👍🏻
Is this a factory locker?
No
Buenos días me gustaría tener el vídeo en español gracias
