Re: 1967 Chevy CST aka "the loud truck"
this is what member "1774btcrew" stated in the thread "I have a very clean 12 bolt spring type posi with 4:11 removed from a 1967 Suburban with low miles." the for sale thread is called "12 bolt posi carrier with 4:11 gears" and is in the classifieds section for 67-72chevrolet & gmc pickups

Re: 1967 Chevy CST aka "the loud truck"
No arguing going on... just problem solving! Are tour axle shafts different lengths?

Re: 1967 Chevy CST aka "the loud truck"
they are the same length. and as for teeth contact i did establish gear contact pattern and the contact was even across when going forward and for reverse the contact was towards the outer portion of the tooth.

Re: 1967 Chevy CST aka "the loud truck"
Rick, I'm not a diff builder but...don't worry about the axles worry about the gear mesh and wear pattern. the axles will fall in after...

Re: 1967 Chevy CST aka "the loud truck"
I was talking to a buddy and he thinks they make a spacer to adapt your ring on that carrier..

Re: 1967 Chevy CST aka "the loud truck"
The spacer would work if he was putting 4.10s on a 3.73 carrier.
Rick. Can you return your carrier and get the 3 series carrier? That would be your best route cost wise. If you wanted to replace R&P you will have to set pinion depth on your new gears as well as pinion pre-load. that's time, money, and tools. (and my favorite part) hit me up if you have any Q's

Re: 1967 Chevy CST aka "the loud truck"
Yikes... Well I don't think ill be getting rid of that 4 series posi carrier anytime soon... Unless somebody wants to trade posi carriers? Do you know who sells or where I can buy a ring and pinnion to still use my 4 series carrier and have 3.73's? Let me know what it's called or where ill buy it. I have access to a lot of tools ( I'm in diesel mechanics in college) so that's not an issue and as for labor and time I think my labor is worth having a posi in there and ill save up money for it, and you guys could help me and walk me through the process. And with this new ring and pinnion will the carrier be centered in the differential housing?

Re: 1967 Chevy CST aka "the loud truck"
I'll check rick, but I think they only sell "thick" sets of lower gears and not "thin" sets of high gears. Which posi do you have (hey you could post a picture since you haven't in a while). You may be able to score an empty carrier for dirt cheap and swap the guts.

Re: 1967 Chevy CST aka "the loud truck"
I think your right! I looked at a picture I took of my axle when there was no carrier in at all and I counted the teeth on my pinion... Counted more then 11! It was a rough pic but there were either 13 or 14 in the pic so what did I do today? Got up went to half price day at pick n pull went to a 68 and what did it have? 3.73! Counted the pinion teeth, there were 11 and counted the ring gear and it was 41 so I took it apart got the pinion and ring gear out and then I went and bought a new diff seal now I just need to get a new crush sleeve and some GM diff lube and positraction additive And install it all

Re: 1967 Chevy CST aka "the loud truck"
Problem solved! Let me make one more recommendation for a new pinion nut. It is a must to replace. I would also check out my np205 thread for some tips on how to seal a yoke. Good luck bud!

Re: 1967 Chevy CST aka "the loud truck"
This is the one from Oreilly's pinion shaft nut
Have you set rolling torque with a crush sleeve before? Best tool to have for that is a buddy. You will probably be good with your pinion depth shims that are already installed too... It's worth a shot to check your set up before removing the shim pack. My other recommendation is to leave out the crush sleeve and use the old pinion nut while you are establishing contact pattern, and then, once you have your shim packs correct, then you can install your sleeve and new pinion nut.

Re: 1967 Chevy CST aka "the loud truck"
Today I guy advised me not to use a set of used gears because there's no way to get the "foot print" the same... Is this really true? I mean if a gear is used then it does have wear but at the same time some have been abused more then others, an the gears I got are not that bad I didn't think it was bad to try and reuse them what do you guys say?
