is it posible to fit 3.42 pinnion gear un a 10 bolt rear axel?

 

yes, depending on a few other factors

 

and will i have to buy a new diff. i will be down the road but i don't have the $ for a new diff yet.

 

If you do not have a 3-series carrier, forget about the 3:42 gears because this will become a big buck item. Look at a rear axle swap.

 

What gears are in your car right now? If they are 3.08 or numercially lower, then you have a series 2 carrier and the 3.42 gears won't work, or at least not without spending alot of money.

 

or you could just buy a ring gear spacer.

 

well i don't know what my geariing is and it's hard to tell cause i'm missing like 3 teath on my pinnion gear and the spyder gears were replaced resently and i tryed to figure out what it was by spining my tiers and whatching the drive shaft spin and how many times my tiers went sround before my drive shaft when once it was in the 3's but it stops for a second cause i'm missing teath so i can't really tell

 

if he does happen to have 2 series gears he can always get 3.42 2 series gears from summit. theyre only like $10-15 more.....

 

yea i know... you guys make it seem so expesive but RG 3.42 are only like $20 more then the other ones... not to much in my book...

 

I think my Richmond 3.42 - 2 series gear set cost me about 190 something. Hell, even Auburn makes 2 series LS carries...

Current Prices: Richmond 3.42 10bolt 7.5" ($186 3 series, and $194 2 series). The extra cost might be because of the extra material on the base for the 2 series.

2 & 3 Series carries are only different in the base location nothing more. Neither is stronger or weaker.

ok so if i get s 2 seris gears and 3.42 and what kind of diff. should i get i really don't want to replace it but it sounds like i ahve to i'm running off my tax return and i'm a 16 year old kid with a 5.75$ hour job at a movie theater so any help would be appreciated how to get around that

 

If you get the new gears i dont think you'de have to replace the old differential... however if you're upgrading from 2.73's you'll prob want a new one... it's probably non-posi right now.

BTW, where do u live? minimum wage here is $7.05

 

It depends on what you have now. The only sure way is to remove the cover and count the teeth. If it's a stock GM set you can tell weather it's 2 or 3 series by the current ratio. You can check if it's Limited slip or not while your there. You can also check the axle code located in front of the passenger side axle (You'll need a good wire brush), and compare to the list in the tech section. However relying on the code alone is not always the best thing, since I doubt you’re the first and only owner of the car.

GM used the 2 series for gears from 2.73 through 3.08, and 3 series for 3.23 and above.
Don't ask why GM switched to the 3 series for 3.23 up. Probably something to do with the economics of the thicker base required. They love saving money, you know.

Aftermarket Richmond gears offers 2.73 through 4.56 in 2 series, and 3.23 though 4.56 in 3 series.

Tooth count:
41-15 2.73
41-14 2.93
40-13 3.08
42-13 3.23
41-12 3.42
41-11 3.73
41-10 4.10
41-09 4.56

You can obviously divide the ring by pinion to figure it out.

BTW: My ’82 Trans Am had a stock 2 series 2.93 Auburn limited slip, so just having a 2 series doesn't mean you've got a peg leg

I totaly rebuilt my 10bolt and it was costly. Almost $1500.00.

If I were you, since you are on a budget, I would get on the net and do a search for auto salvage yards, and try to find a complete 9 or 10 bolt that has a 3 seriese gear (3:23, 3:27, 3:42, 3:45 etc.) and a posi, for an F-Body. I don't know what you'll pay for it but it would be cheaper than a rebuild.

To totaly rebuild your 10 bolt and pay to have it done will cost upwards of $900.00 to $1000.00 if you buy all the parts new and pay for labor (I estmate labor to be around $250 to $350 and a new posi unit around $400 for a nice one, and re-use your old axles if they are still good). If you can aford it, rebuild it, you will get what you want. But make sure you get a written quote on the labor first (before you buy your parts even) if you can, this way you will have a good idea what you are going to spend ahead of time.

Good luck.

 

Just lettin' ya know... I need a rear-end and am also a highschool student on a budget, I called the local U-Pull-It and they say that complete rear-ends are $75 (axles, brakes, gears, differential)

Thought the extra info might be helpful

 

yeah thanks man i think i'm gonna try to find a used ford 9" and then fab. it up to fit in the camaro. cause the guys at u upll are jackass's and say they don't have any camaros when i could see one in the back when we drove by but thanks for the advice

 

Like "ChevyCamaro420" states that if you can get a rear end for $75.00 at a bone yard that would be the way to go. I would do an internet search for a bunch of bone yards, then get on the horn, find out how much and what they have. It would be worth the trip to go get one, even if you have to stay overnight.

I got a lot of parts for my car this way. I would locate the parts I want, then the wife and I pack up the mini-van, get a sitter for the kids, and hit the road. The money you will save will far outweigh the expence incured by traveling to get the part. Plus if you take a week or two to find the rear, you may just come across a good 9 bolt with disks, a 3:45 gear, and a posi! you never know what you will find. I know of a bone yard in Aroura IL that has 5 F-Bodies right now. Never know what they got till ya call.

 

alright thanx i already called the local u pull thier jackass's never have what u want and are mean about it well thies still highway 101

 

The camaro that you saw in the back was probably being sold as a parts or project car. I'de try to find one at a U-pull-It, they let things go for dirt cheap since you gotta get it yourself... Just call around, there could be a lot of local ones depending on where you live. There're 5 U-pull-Its within 20 miles of where I live and there were plenty of F-bodies when I went.

 

well that was the only u pull thier and they rest are auto salvages were i ahev to pay up the but for them to take it out but ford 9"'s will fit in the back of the camaro right? just need to like relocated the shocks and the arms right
??

 

That is a lot of work.

If you want a 9" check out Moser or Currie.

I plan on buying the Currie when my Gov-Loc grenades.

Edit:

There is more to it than relocating the shocks and arms, you have to make a torque arm mount and get the pinion angle perfect, axle tubes may have to be shortened, and you will have to modify the ends of the axle tubes to work with the GM brakes plus it will require custom axles that will work with the GM wheels and brakes etc, etc. I am sure that there is even more to it than that.

For me, it will be way easier to just buy the 9" from Currie and throw it in.

Way less cussing!

 

Most stock F*rd 9" rears suck. They were not exactly known for rugged reliability in the cars they came in. Because of that, you don't want a junkyard rear; they're basically a big heavy POS, no more reliable or durable than a 8.2" 10-bolt, unless you can find one with a needle-in-a-haystack nodular iron center section before the junkyard operator does.

The advantage of them is in the aftermarket support. Lots and lots of people make center sections and pinion supports and axles and carriers and gears and all of the other parts that are terrible in a stock one, that are vastly better than stock. All of those parts just happen to bolt up conveniently to a stock housing. It's alot like if you go to the junkyard and score a Chrysler hemi; even though a Top Fuel motor is a "Chrysler hemi", the thing you get in the junkyard isn't going to make 5000 HP like one of those does. It just happens that the Chrysler hemi is the platform that they base their motors on.

You'll spend a huge amount of work, and end up with something inherently inferior both in terms of perfection in the fabrication and the strength of the parts you'll be using; and probably not save much money at all, if any, in the long run. The money for one of those aftermarket setups isn't really in the housing; it's in the center section, good axles, quality pinion support, good carrier, etc. etc., none of which will come in your junkyard unit; and all of which you'll either have to buy, or you'll have a rear that's not really any better than what you have now, it'll just weigh more.

As far as telling what gears you have now, it's stamped on the edge of the ring gear. Just read it.

3.42s came stock in some of these cars. 3.73s even came in some; I have one.

 

Also, check around to see if there are any salvage yards that only deal in camaros and firebirds. i know we have one here that does and i have heard from a lot of people that it is one of the best places to get parts for these cars.
