J30 VLSD
Hey everyone, I have this J30 VlSD from a 94' that has been sitting here for awhile. I did plan on using it on my 240 but change my mind. Today I looked at it and notice that there if quite some resistance when I try to turn output flanges. Theres nothing holding the input shaft. Is there pose to be some resistence? I can barely rotate it...would letting it sit caused it to seized...is there any way to fix it..?

Re: J30 VLSD (shiftdrift06)
Yea its a viscous fluid diff. Of course you wont be able to turn it when its cold.
Re: J30 VLSD (DominickJ30)
Sorry for the noob question, but do ALL J30's come with a VLSD? If not, what years or model trims came with the VLSD? Thanks a bunch!
Re: J30 VLSD (Td5turbo)
yes, they all do, from 94-97.

i read an article about how the flanges or something are different when installing a J30 rear diff in a 240sx. i have a 91 s13 do you have pic of the difference between the 5 star ones and the 3 sets of 2 ones.iam getting ready for a junkyard quest and would like to know exactly what iam looking for

You cant really miss it. One looks like a triangle with 2 bolts in each corner (3x2) and the other looks like a star (5x1).livefast wrote:i read an article about how the flanges or something are different when installing a J30 rear diff in a 240sx. i have a 91 s13 do you have pic of the difference between the 5 star ones and the 3 sets of 2 ones.iam getting ready for a junkyard quest and would like to know exactly what iam looking for
Look at the Q diff. It has 6x1 flanges (I think). The 5x1 look 'jagged' like that. (thanks for the pic, Brian)
Here's a good pic of the 3x2 flanges.
If the diff is difficult to spin, thats a sign the viscous fluid is still in good shape. Of course, all are gonna be a little harder to turn in cold weather.
I think all J30's have VLSD's, including the 93 model.
