So I ordered a DSS 1pc Driveshaft

[Phyrx]

It seems too long VERY TIGHT fit

I have an s13 redtop sr, nismo mounts, and a J30 lsdThe driveshaft I ordered is for an S13 without ABS... Should I have ordered an ABS driveshaft considering maybe the LSD was from a car WITH abs?

What should I do?

[Emperor_Tha]

a) sell the driveshaft and get abs driveshaftor b) sell the j30 diff and convert the stock to lsd

[slow s13]

yep you should have ordered the other shaft because the j30 diff is slightly longer than the stocker, requirings a slightly shorter shaft

[Phyrx]

Can you put the J30 diff guts into the open diff case??

[Phyrx]

Anyone?

I cant find any info on swapping the diff guts out. Is it possible?

I have this problem all the time lolllll

so waht is the deal with solid drive shafts why is it worth swapping. does it make much of a difference.?

Anyone?

i just swapped guts out in my differential. for a HLSD pretty easy as long as you keep stuff in order. you do needa vise tough. to be able ot torque everything down.

Thanks, I guess Ill give it a try

The reason for the 1 peice driveshaft is because the original owner of my car totally destroyed the 2 bolt holes where the carrier bearing bolts up under the car.... to the point of no repair

Why do I have the feeling you didn't properly reshim the diff and just stuck it in there with the original shims.

If you've done proper differential swapping, you wouldn't say it's pretty easy.

And typically one piece driveshafts are lighter than stock units (not due to the fact that they're one piece, but that they're usually made of aluminum and not steel). Less rotational mass.

because that is how i did it. but it was a perfect fit. lol maybe justa little tight but it slid together good. i haven driven the car yet. but should be fine. diderson did the same thing.

^^ yep

Also, as I've said before, anyone running a one-piece driveshaft, needs to have an NHRA approved driveshaft loop installed. Any performance or off-road shop should be able to do this. You don't want to find out what can happen when your u-joint breaks up front by the trans and you don't have a loop installed. Car launching into the air is no fun. My .02

Trust us. If I were you (and goes for Didderson too) I would bring it to a qualified shop that does diff installs and have them re-shim it. Not only does it make for a quieter running diff, but it reduces wear and tear, and possible breakage do to the presence of improper tolerances/excessive (or lack of) play. A diff that locks down while driving at speed, is also no fun. Again, my .02

^ THANKS. but i would gaurantee that my differential is going to work perfectly. as far as shimming there is alot of people on both sides of the fence.

it was actually quite straight forward. when doing the swap i was supprised. I took my time at it. didnt rush it. made sure to torque to the correct specs. used thread lock. it isnt going any where lol.

thanks for our guys input...... if i am wrong i will not hesitate to say so

The only sides of that fence are the ones that do it right and the ones that do it wrong. Poor backlash adjustment will result in premature ring gear failure. And the only way to confirm backlash adjustment is if you took the time to check tooth engagement with a solution like prussian blue and played around with the shimming. I've put 3 differentials together so far and none of them have chattered or broke. I was also taught to do it properly by a man who has been working on cars longer than most of us have been alive. I've been lucky that I haven't had to reshim the pinion gear yet.
