Whats my inner spline count?

[rain_man_rich]

1990 Loyale Turbo MPFI

4sp Automatic 

Full time awd/4wd (whatever it's called)

 

Try as I may, I find conflicting evidence as to the number of splines.  I just ordered from Rock Auto and they sent me 23 splines.  I don't want to tear down the axle just to find I have the wrong one then send parts back and forth while the car is out of service.

 

Thanks in advance for the information

Nvr mind my first post I don't know why I was thinking Lego.

Here is empi info from rock auto

http://www.rockauto.com/catalog/moreinfo.php?pk=2977926&cc=1270099

It says 23. I believe I have heard about the early turbo autos having the twentythree spline count.

Hope this helps

25-spline.  All 4EATs on EA82-platforms are 25-spline.

Next time I need to replace a half shaft and don't know the spline count, I am going to pop out the roll pin on one side and slide the DOJ back enough to count the splines. Then put it back together until the parts  (correct parts) come.

So this is what I got yesterday from three local parts stores, Autozone, Napa, and Oreilys:

 

Autozone:  23 spline, reman and new

Napa: 23 spline only, no 25 in database

Orielys: reman 23 or new 25

 

Talk about a mess,  at Orielys I had them both on the table and showed the salesman that one had 23 and the other had 25.  He just stood there and looked stupid. Rock Auto sent me one with 23 for turbo and automatic trans.  I'm following Mark Humble's advice tomorrow.

Most turbos have the 3AT automatic, which does have 23 splines.  88-90 (IIRC) turbos could be had with the 4EAT 4-speed.  Sometimes, parts computers can be worse than useless...

[rain_man_rich]

Can the spline count be had by merely popping the roll pin and sliding the DOJ back far enough to count? Or is there more to it?

[NorthWet]

That should work fine... if you don't lose count like I do.

[MilesFox]

25 splines. tell the parts counter 'full time 4wd' or just turbo with a manual trans. Don't count on the parts counter listings unless you already know them with the year overlap groups between platforms. anything you are looking for will be 88-94 with 4spd automatic. rule out any 3spd automatic listings altogether.

[Gloyale]

Just order for Manual trans turbo car.

 

then you will get 25 spline every time.

Thanks for all the replies.  This board really helps a lot of people

My advice: skip the parts desk altogether until you know the model, year, and options the part you need came with as stock. The more stuff you do to the car, the more you have to know. I recommend writing a list, and add to it every time you do something to the car that involves swapping in parts from another year, make, model, option set, etc. It will eventually save you time, money, and trouble.

 

Even the oil change I got a few weeks back threw the garage guy for a loop since I didn't have the original motor in the car . Ditto with the dealer when I went in with a disty problem a couple years back...he called me up: "Umm, this is a California car, without a California engine..."

Just get used to it and have fun

He hasn't swapped anything into the car.

 

Problem is hte parts catalogs don't make the proper distinction between the 3AT models and the 4EAT model turbo cars.

 

the catalogs are notoriously wrong on disty caps, intake gaskets, and a whole host of other model specific parts.

 

I've eve had alot of trouble getting the right clutch and axles for EA82's and instead getting EA81 axles.  Since they were both offered in overlapping years, with 1.8 engines, and called "DL" and "GL" models.  the only identifier in the parts catalogs is weather it's a wgn/sdn/3-door or a hatch.

 

my general rule is if you need EA82 parts, order them for a wagon.  If you need EA81 parts, order them for a BRAT, so you won't have the EA81/82 overlap that the cars do.

[man on the moon]

True, but I'm guessing he will be swapping things in .

Good to know re: EA81 vs EA82 trick, I've wondered about that.
