[1989240sx]

i was thinking about getting a one piece Aluminum Drive Shaft they car is going to be a daily drive is there anything i should be worry with it being aluminnum ? where would be the place place to get one at i was thinking of grtting it from 240sxmotoring.com

[Razi]

As far as I know... Nothing to worry about.
The one at 240sxmotoring seems legit.

having a Aluminum Drive Shaft will be okay for a daily driver ? and what are the benfits of having one ? is there anything that i need to do to the car so i can put it on or does it bolt right in and i have nothing to worry about

[biggie]

Check out the sponsor Shaftmasters, very good ones.

No problems with daily driving and they bolt up. You get rid of the joint in the middle of the OEM driveshaft and the carrier bearing on it that can go bad. Also much less weight.

so you want to buy an aluminum drive shaft, but you dont know why.

I'm sure the money you're considering putting into the drive shaft could be used better elsewhere on your car.

Aluminum Driveshafts are perfectly fine for daily driving. They are great, you could possibly even notice an increase in fuel mileage. With a one piece solid shaft you may hear a little bit of noise when shifting or just a tiny bit of diff noise. Nothing bad at all just because you are eliminating the center support bearing and rubber insulator that causes power loss and slop. Just go for it, it is not a bad upgrade at all.
Make sure you also change the rear seal on the transmission when you replace the shaft since it is right there.

The Driveshaft Shop makes a really good driveshaft. Shaftmasters does too, the one on 240sxmotoring.com looks like the Shaftmasters units. I have dealt with both and they are both great quality. The Driveshaft Shop one does have re-greasable U-Joints which is a definite plus, i also like the way theirs is balanced. Both are really good though!

They're lighter and, from what others say, it allows you to break the tires loose easier. I have a 1 piece steel drive shaft. Even the steel one is lighter, but other than that I haven't noticed any difference

Just go for it, these are the kinda mods you do before you touch the engine. It's always better to increase efficiency then throw some extra fuel and air in the motor.

[1989240sx]

i have my deive shaft on it way here can't wait should be here tuesday sep 20 should i put a chain where the carrier bear was so i dont have to worry about it fall on the ground if it does slip out or i should not worry about it

[Hoffman5982]

I don't have mine on. The only way it's going to come out is if your engine or differential were to fall out, and at that point you'd have a lot more to worry about than the driveshaft

[1989240sx]

yeah true i was think abouts using one of the brakets that hold the carrier bearing but i dont think i am going to worry about it i know on my 74 duster is does not have anything and it still on there

[1989240sx]

so i am trying to put in my driveshaft before i have to go to work is there anything i should to to make the install easier i seem to be a close to going in but it does want to go in, is there a way i should have the car should i have the rear higher than the front of the car or should i have the front highter than the rear of the car

[biggie]

Having it level would probably be preferred.

Shouldn't be any tricks, should slide it into the transmission, then bolt it to the diff.

Only issue may be if you have the metal dust cover that is on the S14 transmission, but that can be removed (about one tap with a hammer).

[1989240sx]

i was wondering should there be any space between the transmission and the drive shaft, can someone post some pictures for me so i can see how much

[1989240sx]

so i had to unbolt the rear end the angel the drivshaft on there but i got in on did not here anything when i lower the car to the ground but not sure how close the driveshaft should be to the rear of the transmission

let me know what you guys think about the distant

[biggie]

If its pushing up against the transmission that is an issue, usually there is a little space there, maybe a 1/4 inch or less.

[1989240sx]

okay should i try a feller gauge and see how much room there is ? what do you think about the picture ? i also have the drivershaft when i had in in the air and i did not hear anything too i am still just not sure about it i know what i did a driveshaft on my duster there was room for travel but this looks like there is none

[biggie]

Looks like there is some kind of dust cover, if its too tight just remove that cover on the end of the transmission.

[1989240sx]

okay so i have the driveshaft off i am trying to figure out what rear end i have is there anyway to tell there are some letters and number on the buttom of it one of them say 8x the other say okn26

[biggie]

The diff is most likely the stock R200 open diff. Unless you somehow have ABS and the LSD option. Or someone has swapped it in.

For DS differences you can search for S13 ABS vs Non-ABS Differential, you'll see in pics that the ABS has a sensor just behind where the DS attaches and is slighly longer than the non-ABS diff, like 1/4 inch.

[1989240sx]

i order a driveshaft for non abs and it does not fit and there is no sensor, is there a different diff for a 5-speed

[biggie]

Nope, should be either ABS or Non-ABS for the DS. And most likely you would have non-ABS.

[1989240sx]

do you know messurements of the different rear end ?? the messurement i got from the transmission rear seal to the rear end where the driveshaft bolts in i got 44 7/8

[biggie]

I don't know. Would be easy to spot if the rear diff has an ABS sensor or not in it though.

Sensor here is between the mounting point of the car and mounting of the DS:

[1989240sx]

my rear does not have a abs sensor i am having a issue with one of the studs in the car i cant get a nut to tight up on it every time it start to tight up it becomes lose again my question is can i replace that stud or do i have to grid it flat that drill a whole and make thread to put a new one in

[OM3GA]

You should not have to remove the dust cover as long as there is some clearance. It will never move so you should be fine. Some Driveshaft manufacturers recommend removing it but if there is around 1/4" clearance you are fine. Also that picture you posted does not make much sense to me lol. Where is the back of the transmission where the seal is?

[1989240sx]

i have the driveshaft issues is solve the issue i am having now is that two top tubs on the rear itself had no threads and now i cant get a nut to tighten down
