i found this diferential, but i dont know if it is lsd !!!

[maik21]

what do you think? it has aparently the abs wire !!

[maik21]

two

3

[GhostDriver]

Spin one of the outputs and if the other rotates the same way its a vlsd. If they rotate opposite, it's open.

[maik21]

rotates oposite.... now ... i phone call the seller man and he told me that its a positive diferential... lsd.. because he burn the tires and the he burn at same time both tires ... now... i need to swap, test and return =(((((

[maik21]

it has the abs plug, and because that, its a confusion !!! money to trash !!! =((((

[cdlong]

crack it open. you already have it out of the car, it isn't that hard.

[Chezedik]

Assuming it has not been modified, then it is not. The rear cover has four studs, for whatever reason the VLSD was two stud. Not to say it still is not LSD. My LSD is four stud, but only because I put it into a non-LSD housing. But cracking it open will require you to replace a very difficult to find gasket. Oh, and VLSD spins opposite and so do open diff. Until you reach breakaway torque of 45lbs it will not lock.

[maik21]

you give me a ray of light =)))) thanks...now, i have a little of hope.... well.. i dont speak english very well... i hope that i understand what you say =)))

[Chezedik]

No problem, if you decide to get rid of it, I might want to take a crack at the R&P. I installed my own LSD and even though contact looked on center, it may not be. If it shears off, I will need another Ring and Pinion. If you decide not to, try a Phantom Grip. I hear good things about them, and they are affordable and easy to install. When you put the VLSD in the non-VLSD housing, the passenger output shaft sticks out a little from the housing. Not so much as to cause a leak, it just looks weird. There is your second clue. This is because it cannot be installed (so that it will lock) without a longer input shaft on the passenger side. Otherwise, the shaft would not reach the Viscous Coupler. What's worse, is that it would not snap and lock in place, and the diff would leak like crazy. Hope that helps.

just use RTV.

[Chezedik]

Yeah, I did that, but it still leaks.

[Chezedik]

But I am thrown off, because I thought all of the ABS models were VLSD in the SEs. But w/o a viscous sticker or only two studs, I guess not.

check the test... i see that its a open diff .. but .. ??????

[Nameless EJ6]

You people who like to spin differentials to verify whether it's an LSD unit REALLY need to abandon that procedure.

VLSD's operate under load and heat. With no load, and no heat, it is open diff.

Helicals will also operate exactly as an open diff unless they are under load.

The one true way of knowing is to split it open and LOOK at it.

Huh? Very difficult to go down to Advance Auto Parts and buy a gasket for less than 10 dollars?

Maik open it up. Take a picture of internals and what numbers the ring gear has stamped into it.

Like this.

[maik21]

thanks for help... next week , i open it before try to put into my car and take some pics =))) thanks for help !!!

[Chezedik]

I used to work at Advance, they do not have a gasket for the R200 diff, they list our cars with some other diff. The gasket is close, but a little too small, and the bolt holes aren't quite right.

[maik21]

the only shop were i live is autozone and dont buy that gasket , i will try it with the car =) thanks... its a totaled confusion... the tests.. all seems to be bad and seem to be i got the wrong dif.. but some of you say that to the dif work, need other things that only can test with the dif into the car .. the more faster thing is open the dif and see what is inside, but i dont want to replace the gasket with silicone or other stuffs , iits a dilema !! i thanks for helpme !! well... after all, i will need to cut the driveshaft to fit with this diferential.. because i use a complete driveshaft from transmision to the dif, because the motor and trans swap !

[Chezedik]

Make your own gasket, you can buy sheets of it. You just get some dye and smear it on the back part of the housing then put it on your gasket material, then cutting it out. The picture shown is the Viscous.

[Badfish]

The one I bought at Advance fits perfectly on my R200v

Its even says on the box. "Nissan Datsun 200sx,240sx,240z,260z,280z,280zx,300zx"

[Chezedik]

This has been months, maybe they finally straightened out the listings. When I first started there I couldn't get a head gasket set for my car listed under the 91. They still don't sell the head bolts. But that is good to hear that they have it now. I do need one.

[574-240sx]

With the abs I would say its a VLSD. Like it was aid earlier just pop it open and take a look. clean off the old gasket with a scrapper then seal it with red RTV following the directions.

[Chingon]

mexican 240sx had a bunch of options to them. Youc could get abs but no lsd, or lsd and no abs... It's really a ***** to know... About the gasket.. the manual says use gasket sealer. I know nismo and kaaz offer new gaskets w/their lsds, but manual says liquid gasket.. just go w/that.

open

clsd

vlsd

[1990flatblack240]

so without opening the diff theres no way of telling if its a lsd or open?

[mallbor240SR]

yeah id say take the diff cover out, it aint that difficult to put it back with just a little bit of liquid gasket, or just make your own gasket out of some yellow folder paper, thats what i did and ended up with no leaks at all, come on man you swapped a v8 into your 240 dont tell me you cant take the cover off your diff jeje.buena suerte bro

[Alfador]

so without opening the diff theres no way of telling if its a lsd or open?

Only if you already know a serial # or exact model and whatnot, then its just a case of lookup, but otherwise you really need to open it, because differential casings dont really have to be any different for an LS

you r right ... i take a pics this tuesday for all of you to watch the dif... now i cant, but tuesday i will can =)
