yo, I'm putting my driveshaft on now b/c I had to swap it for the 5 speed swap. Anyway, I put the slip yoke in first, then the center carrier bolts, then I attemptd to put the bolts in where it meets at the companion flange, BUT the DS is a little bit too long (maybe 1/4inch?) so it won't meet it correctly. So then I talked to my tech friend online and he told me to put those 4 bolts in first, then the companion flange bolts, then put the slip yoke in, BUT that doesn't work b/c the slip yoke is too long and HAS to go in first. SO then I tried putting the slip yoke in first, then I put the 4 bolts in at the companion flange, and then attempted to put the 2 17mm bolts in for the center carrier but when I push it up, it's too low. I mean, I COULD push it and hope that it gets up there but I could break something (u joints). What should I do or what is the proper procedure for this? thanks

Is the driveshaft the correct 5speed, non-abs driveshaft?
Driveshafts are fairly easy to do, it just sounds like your stuff is the wrong length.

hmm, I'm pretty sure it's from a 5 speed b/c I specified that when I bought it from the junkyard but I forgot all about the ABS thing. I just assumed that the 5 speed driveshafts were the same :doh:

So does this mean I have to buy a new driveshaft?

PS- How would I know if it's an ABS or Non-ABS driveshaft?

ok, I'm quoting R240NA here:

"No. Transmission splines are different. You need a manual driveshaft, ABS or not since the ABS is just a hair shorter it still works fine. Bolt it up to the diff, then put the carrier bearing bolts in."

So I guess it doesn't matter which DS u use. Question still stands.

get the correct driveshaft for the applications. Unless you like vibrations.

1st section (no difference for ABS/non-ABS):
M/T: 395.0mm (15.55")
A/T: 432.0mm (17.01")

2nd section (no difference for MT/AT)
non-ABS: 605.0mm (23.82")
ABS: 590.0mm (23.23")

15mm is 9/16ths of a difference. Thats not a hair.

well, I read that the ABS driveshaft is shorter by a little bit, meaning that the Driveshaft would've gone in if it was the wrong one.

Trust me with enough force it'll go. I've done it. THen come to think about it. IT also left a slight bend in the drive shaft which will cause some vibratios and wear out MANY parts, especially the extra pressure it puts on the diff. When i install my drive shaft there is some play in it

Ok, start by measuring the length of the driveshaft you have in your hands.

Then, see if you can figure out if its the right one based on the dimensions someone posted in here.

If its the right one, put the spline in, bolt up the rear section, and then the carrier bearing. Be carefull not to strip those bolts.. but give the DS a little push at the center (upwards) and make sure you don't catch your fingers..

use the non-abs driveshaft. thats the correct driveshaft for your application. or else, if u do get it in, u will have problems u probably wont wanna deal with. why not do it right the first time? im a perfect example of not doing things right the first time...read my other threads.

Update: I finished everythign and I started the car to see if everything is ok. Everything was fine till the driveshaft started spinning, lol. :doh: :doh: :doh: :doh: :doh: :doh: :doh: :doh:

I'm a fucking dumbass. anyway, the driveshaft was rubbing against the extension housing which creating friction which in turn created smoke :doh:

So obviously I don't have the correct driveshaft. And it doesn't even matter if it's for ABS or non-ABS b/c everybody is saying that the ABS driveshaft is shorter, meaning that I wouldn't of had this problem if it was an ABS driveshaft.

SO, this leads me to believe that teh junkyard sent me the wrong driveshaft. maybe even one from an s13? don't know really. And I don't know how u guys measure your driveshafts. Should I measure from one flange to the other?

Yes, measure the total length of the DS.

Did you install the carrier bearing properly? It shouldn't smoke even if it was spinning inside it.

yeah, I installed the carrier bearing properly.

And just to let u guys know. I"m using an s13 tranny on my s14. I just got this reply from a guy on 240sxforums:

"are you using a s13 transmission if so you need to knock off that metal ring at the end of it cuz s14s use a much wider one there its not even needed."

is anybody here aware of this?

No, never heard that. I too am using an s13 tranny in my s14 and I didn't have to do any of that.

hmm, weird. conflicting information damnit. I hate when that happens.

Update: the rear piece that hooks up to the diffy is 25 and 5/8ths from flange to flange. That is the same as my old auto. driveshaft so I don't have the wrong one.

But it's pretty hard to believe that nobody except for that one guy has knocked that ring out of the extension housing to make this work.

u need to measure from the tip of the part that goes in the tranny to the flange that bolts to the diff..

onece u get the total length should be 15.55 + 23.82 = 39.77" so around there for a non abs drift shaft

if its the same length as your auto one you have the wrong one... u need one form a 5spd.. which is shorter...

dude, I"m talking about the rear section. lol. They are SUPPOSED to be the same. I'm NOT talking about the front section, which is obviously different.

another update: I took out the ring which I believe is the dust cover and now it fits fine. The reason why I had to take it out is b/c the slip yoke wouldn't go in all the way b/c of the dust cover. So the s13 dust cover is a bit too small for the DS. So now everything works properly but I also have to figure out where to get a dust cover. Maybe I can use one off of an s14 tranny.
