j30 lsd fluid

[the a3k]

I got a j30 vlsd and I had to fill it with fluid. I got 75w90, drained the remainder of the old fluid, and filled it with 2 quarts. I read that it takes about 1.5 but I wasn't sure. Do I have to top it off? I filled it with a third quart and its still not full.

So do i have to top it off? If not, what is the correct capacity?

I looked through dozens of threads and all say different things

It should start coming out of the fill hole when full. Should hold about 1.5 qts.

[the a3k]

There's 2 holes. Bottom for drain and side for fill? Which angle should I have it in when filling and which hole should I fill it from?

I installed full suspension, took out the old diff with no probs but the lsd is making me feel like a noob lol

[Josho]

Lol. It happens man. Sounds like you're doing it right. The hole on the side about halfway up on the left side if you are looking at it from the back. I use a pump to fill mine up. Make sure the car is level, wheather its jacked up at all four corners or sitting on the ground.

[the a3k]

The diff isn't on the car yet. I had it on the side that's why it took 3 plus quarts. I gotta level it then drain the excess fluid. Noob fail lol

[Josho]

Hahahaha! Ok man.

[the a3k]

Thanks anyway man lol. The diff is going on tomorrow or next week

[SRTFerg]

What fluid did you use?

[the a3k]

valvoline 75w90 synthetic LSD. I know the j30 Vlsd is a sealed unit but whatever lol

[SRTFerg]

I hear ya. I have a j30 ill be throwing in my s14 tonight and I just went and blew $80 on Redline fluid. hahaha

Nissan recommends Pennzoil gear oil 80w90

[the a3k]

I'm not gonna beat on it, yet lol. I'll use 80w90 next time.

[Josho]

GL-5, 80W-90. S15 fsm recommends this oil and recommends against use of LSD oil of any other type, brand, grade or weight.
