I got a hold of the guy with the 82 / 81 (he posted it as an 82 but said he said he ment 81.
The thing is he said they pulled out 411 gears and all I need to do is just
(stick a set in?):dontknow:
I thought a rear end (needs) to be set up by someone that deals with those. Not to say anyone can't do it but I think it's more involved than just (sticking in a set of gears?)
I could always swap rear ends, mines a 10 bolt posi. but with the overdrive I'd like lower gears.
So how hard is it to do?:dontknow:
Donny

Donny, it is not that hard but it does take some tools and some know how. Most do not have the know how because of the rarity of having to do it most have never learned how.

I've had done some rear ends in my time,and its not hard at all. (furds ,Chevys is all i've done.) as long as the teeth meshes up and the proper backlash.its easy.:beer:

odds are you will need a different carrier, they change series some were around 3.42 if im not misstaken.

Make sure you have someone who will do the work before you spend the money. Most shops won't touch used gears, because they have worn in a pattern that matches the original installation and no longer match the depth and backlash numbers engraved on them. Used gears often wind up being noisy and have to be set up with white lead and by eye - rather than dimension and they don't want to spend the time and still have an unhappy customer.

3.08 and lower are a series 2 carrier while 3.23 and higher are a series 3 carrier, if you have a series 3 carrier then the change isnt that bad ,just need new bearings on the pinion gear and a new crush sleeve . If you have a series 2 carrier then there is more work involved . Any idea what gears you have ?

Really what I'm wondering is how hard to it be to put back 411s it the one he took them out of. I doubt anyone would do those gears in a non-posi rear would they?:dontknow:
But that way I could sell my 10 bolt posi and recoop some of my money. Theres a certain someone who I won't mention (steelbeast) that has done everything he can to talk me out of it!!!!
If it had 411s would they gock back in fairly easy or do I run into the ( Most shops won't touch used gears, because they have worn in a pattern that matches the original installation and no longer match the depth and backlash numbers engraved on them) issue?:dontknow:
Donny

DO NOT RUN USED GEARS IN A DIFFERENT REAR END YOU ARE ASKING FOR BIG TROUBLE AND LOTS OF $$$$$ DOWN THE DRAIN ILL SWAP YOU MY 373 FOR YOUR 308 POSI YOU PAY FOR LABOR IM JUST SAYING////////:beer:

Not mine, the body I'm looking at buying. They pulled the 411s out so it has no gears?
Donny

Putting gears in a rear end requires that the pinion depth be set. You set the depth of the pinion to a dimension and you adjust that depth by torquing it and deforming a crush sleeve. The crush sleeve is a one time use only.

You can't just open the cover and put the gears back in. A good rear end shop can do it, but you have to find one who will do, since most of 'em won't touch used gears. As far as I am concerned, pulling the gears out of a running and properly setup rear end is a bonehead move and just gives you two big, oily paperweights.

Why did they pull the gears out? There has to be something in that part of the story too.

"...... Most shops won't touch used gears, because they have worn in a pattern that matches the original installation and no longer match the depth and backlash numbers engraved on them......"


".......DO NOT RUN USED GEARS IN A DIFFERENT REAR END YOU ARE ASKING FOR BIG TROUBLE AND LOTS OF $$$$$ DOWN THE DRAIN......."

Not trying to get into a wizzing contest with anyone but by that reasoning anytime you have to change carrier bearing(s), pinion bearing, or installed a different carrier (i.e. going from an open rear end to a posi) then you would have to also replace the gear set because you can never get the ring and pinion set exactly as it was when you took it apart.....and that ain’t so folks.

The shop I work at replaces bearing and occationally gears on a regular basis with no problems and I personally have run and am in fact currently running 2 rear ends with used gears with no noise or wear problems. The key is a good set of gears AND proper setup.

I have seen more problems with new gears not properly broken in (yes you do have a break-in procedure for a new gear set) than I have with properly set up used ones.

Why did they pull the gears out? There has to be something in that part of the story too.

This car was used to race in (a little?) they rebuilt the front end and it's a solid boby. They said they pulled the motor, trans, and the 411 gears for another project. He said it like it was no big deal and added he would check and see if they had any others. I've been told to a posi set up you need someone that does that. It has to be set up right. Can I pull my motor, trans, and rear end and (drop) them in another body? Sure just takes time. But can I set up 411 gears in a posi rear end?????:dontknow:
Not something I care to mees up.

Mike: I agree that someone who knows what they are doing can set up a used set of gears. But it takes skill and knowing how to read the tooth pattern. As a result - at least in my experience - most gear shops insist on installing new gears, because they get far fewer complaints. Finding a shop who will install used gears can be tough.

I have been running a used set of gears in a used posi carrier for the last couple years which I changed in my back yard .I would just recommend always use new bearings , new crush sleeve and a good set of shims ,.

ive also done the used rear posi deal i was 19 and never done them luckily my grandpa was there and helped me out.
used gears dont mean theyre unusable if their in good shape it will not give you any problems.
as long as you use white lithium grease to check that the teeth are meshing smoothly and evenly

Not asking about the right size, my question is would this be a (drop in)?

who's that "boom boom" woman he refers to? post pics!

:nanawrench:

I prefer good used gears over new. the pinion depth has already been established by the factory. the inner bearing and correct shim is usually still installed. I just change out the bearings, keep the factory shim, set the backlash and you are good to go. New sets do require some break in and will usually make some noise to start with even when setup properly.
the guys I know that make their living building and selling rear ends prefer good used gears. There is no reason to throw away a good set.

A little confused here it says 8 inch , chevy rear ends are 7.5,7.65,8.2,8.5.

7.65 will fit in a g-body but you have to change axles as gbodys are 26 spline and most vehicles fitted with a 7.65 rear end are 28spline axles. so if its a 7.5 fitted for 26 spline axles it is adrop in , if its a 7.65 is a drop in but needs new axles , if its 8.2 , or 8.5 it will not work. even if it is a drop in you should get new carrier bearings pressed on.

well, i want to change my ring and pinion but am confused by Motive: they say my 85 elky, since it has a 2.41 r&p CANNOT be changed without changing the carrier. Every one else says my 2 series carrier will accept any old 7.5/7.625 3.08 and some new aftermarket r&p's here to fore regarded as 3 seies but are being produced with a thicker ring gear to fit the 2 series without a spacer. Motive says NO... that my 2.41 carrier is stuck with it and the "2 series" carrier that will accept a 3.08 or larger is in fact a SEPARATE and DIFFERENT 2 series carrier that begins with the 2.73 r&p as its lower limit, numerically. WHO IS RIGHT??? worst nightmare is buying a "thick" 3.08 or 3.23 that supposedly fits a 2 series and tear my 2.41 down and find it does not!

I just figure out why "Donny" wants to changes out the carerier ..
