i have an 84 stock TA with 3.73 (one wheel wonder) gears in it. i need to know if i can just buy new gears to get a 3.73 posi and if i can what's the site that has them.

 

also i think it is a 7.5" 26 Spline but am not 100% sure nor am i sure what that means. so if someone could explain it that would be very helpful. if that is what it is is this what i need summit P# 109-542044

 

doesn't anyone know anything? please help me out here

 

26 spline axles in 84. you don't need another gear set to make it a posi, you need a new carrier, you can reuse your old gear set

 

hey, EDE where would I get a new carrier? What site?

 

does anybody else know where i can get a new carrier that EDE is talking about? and what i need to look for when getting one as well as where.

 

You can get a carrier from auburn, eaton or a variety of places. I would look on e-bay for a 26 spline 3 series carrier. You can go with the zexel takeoff from SLP for $99 but you would have to swap over 28 spline axles. Which would be a good thing anyways.

 

i thank u for your help but the last thing i am wondering is what is a carrier?

 

It what the ring gear bolts to.

 

i just found something out tonight. my boss has a 99 TA that had 3.42 posi but he got new 3.73. he sed he still had all the stuff to make my car posi, but can i still use my 3.73 gears? and i bet i would half to get new 28 spline axles too right? i i do, what would they run. (or what specs do i need other than the 28 spline)

 

doesn't anybody know if the 4th gen gears will work in my car? and if it will take my 3.73 gears

 

gear set from a 4th gen will fit and work, just make sure the carrier series is the same.

 

ok, mabye i need to ask in different words. do i need to change anything on my 84 TA to make his 99 TA rear work in my car? mine right now is 3.73 open rear end, his was a 3.42 posi. i want to keep the 3.73 gears from mine but use his old parts to make it posi. so once more. do i need to change or get anything new or different to do this? keep in mind i don't know ANYTHING about rear ends so advising me to make sure the carrier series is the same is pointless bcuz i don't know how to check and what i have? right now with this carrier stuff i'm VERY

 

this is all i have fom my RPO

Y06 : RING GEAR, 9.50 IN., SAGINAW, (S.P 0.)
GT4 : AXLE REAR, 3.73 RATIO

and it sed it was unable to locate codes: 17C E6N WS5 WY6 and i'm about 99.9% sure i type them in right so if anyone knows what they mean, please let me know. (and i'm sry this was sorta of the subject)

 

i dont think youll be able to use 4th gen 28 spline axels because theyre 2" longer i believe. youd need axels from a 88?-92

 

i figured that i would need to up grade to some 28 spline axels ffrom a later 3rd gen, (i'm not sure but i thought 84 was the last time the 26 spline was used with TA's) but what about everything else, like the carrier and using my 3.73 gears instead of his 3.42?

 

3.08 and lower is a 2 series carrier, 3.23 and up is 3 series, so your gears will work.

 

thanks for all your help KagA152, i know i'll need some 28 spline axels so can u advice me on where to get some cheap ones? and i need ones from a late 80's, right?

 

Junk yard is the only cheap place to get those thirdgen 28 spline axles. Otherwise you can get any length/size axle (for the most part) that you can dream up from places like Strange and Moser. A set for something like a C-clip 10 bolt will run you about $260 shipped to your door.

The spline of the carrier and the axles needs to match. No mismatching. Ever, period.

Ede covered this, but once again, any 7 1/2" gear set will work on any carrier - posi or otherwise. No need to change gears to go from non-posi to posi.

Right now you have 26 spline axles and a 26 spline open carrier. Most aftermarket carriers are 28 spline for the 7 1/2" 10 bolt but I know the Auburn can be had in 26 spline. The cheapest way for you to get a "posi" is to buy a Powertrax or a minispool. The minispool is a bad move on the street as it will mechanically lock the axles together and eventually something will break. Not to mention it makes the car drive like poop and push the front end all over the place. The Powertrax is a bolt in locker assembly that replaces the spider gears inside your existing open carrier. They will still allow differentiation of the axle but will lock the axles together when you are accelerating in a straight (or fairly straight) line and thus spin both tires (given there is adequate power to do so).

How much money have you set aside for the budget for this project and would it be an accurate assumption to assume you will be paying someone else to do any mechanical work on this project?

All comes down to money really.......
