I was trying to remove my axles today to get my disc brakets on. Well the 5/16 bolt that i have to loosen to pull the pin out, i cant reach it with a socket right. So i tried the box end of a wrench not the opened. It didnt round it off but the wrench kept slipping on it and not turning it. I dont know what else to do i dont want to round it off andy specific tool i need to be using. Thanksin advance
It is a factory open 3.08

 

I have a 6pt box end wrench that I use.

 

A 5/16" six-point socket and a quarter-inch breaker bar worked for me.

Ok thats all i need to know. I was using a 12 point cause i didnt have a 6. Thanks alot guys

 

Yea, you absolutely need a 6 point wrench. Napa special ordered one for me. Here's hoping you didn't round it that much, it's a bear to deal with if you did.

 

Sears stocks 6 pt. wrenches.

Thanks guys..... Got it taken care of... Not rounded that much but did order new bolt before it rounded completely

 

Did ya order some 373's and a posi to go with your new bolt

 

NOPE. dont really have anyone to change the whole thing. If it was just a gear i would but i can only go up to a 3.08 with that pinion right. actually cant i put a 3.23 in it withour changing the pinion. Cause i was looking on Jegs and My pinion is of course a 13 tooth pinion. The gear is a 40 tooth, and they have a 3 series carrier for a 3.23 gear that has the 13 tooth pinion. But i dont know anything about gears.... what can i use in that to just throw in there and not change anything else. Actually what is the difference between the 2 and 3 series i dont even know.
I cant afford to loose out on the car right now. I am already doing a 1LE swap front and rear.

 

Series two will accept up to 3.08's, series three 3.23's up.

Ok but i looked on jegs again and they said they had a series 2 carrier 3.23 i has 42 teeth and a 13 tooth pinion. So tha works i'm guessing but still no posi. Is that correct

 

If you intend to buy a carrier (posi) someday, then DO NOT buy the "special" thick gears!!!! Doing so will lock you into a 2 series carrier forever. Use a spacer instead, so you can take it out and use the right carrier. 3 series posi carriers are FAR easier to find, new. You don't want a used one anyway, because at least 9 times out of 10, they're worn out. They're just junk Auburn units in these cars, which you wouldn't want even a new one of.

You CANNOT just change one gear. BOTH the ring and pinion must be changed, AS A MATCHED SET. They DO NOT interchange, even between 2 sets of the same ratio and the same mfr. So no matter what you do, you're looking at changing the pinion. There is nothingexcept a carrier (posi).

The difference between a 2 series and a 3 series carrier is the location of the ring gear flange.... since "ratio" is NOT ONLY the ratio of the numbers of teeth, BUT ALSO the ratio of the ring diameter to the pinion diameter, and since the ring is ALWAYS the same size regardless of ratio, then it should be clear that as the ratio INCREASES, the pinion size DECREASES. That's the reason for the "special" gears being THICK: they make up for the much smaller pinion in the higher-ratio gear sets. The factory, however, makes the lowest-ratio carriers with the ring gear flange in a place, and then as the ratio increases and the ring gets too thick (expensive to make), they move the flange it mounts to over toward the pinion, and start over with the mimimum-thickness ring.

In this model of rear, there are only two "series", and the break is between 3.08 and 3.23.

Here's pics of a 2 series and a 3 series carrier, side by side. Note that both of these are posi, and both are Auburn; the one on the left is a stock 2 series, the one on the right is "high-perf" 3 series.



Note how on the 2 series, the back side of the ring flange is kind of flat, where on the 3 series it's kind of cone-shaped, to move the ring over toward the pinion by about .400".
