Busted diff bushing. Swap it out with a set of aftermarket ones.

what is the part # and where can i pick up from? Can it wait or do i need to fix right away?

When you replace them, do so with Whiteline, not OEM.

can i do myself or i need to take it in? Can you someone please attach a link to that part i need to order?

not sure if warranty still cover this? my car is 2010 with 30k miles.

Standard warranty is 36 month/36,000 miles bumper to bumper, 5 year/60,000 mile powertrain so you are out of warranty unfortunately

I would check with the dealer and see if they will cover the labor (under warranty) then I would order a set of white line rear diff bushings and take that to them to install..

Unless he picked up the extended warranty ??

NO extended warranty...how much do u guys think its going cost to install? looks like Z1 is out of stock on them?

If you ever wanted to swap to the nismo diff cover, it'll probably never be cheaper. The diff is coming out to replace the bushings anyway.

And put some Redline in while you're at it.

which Redline do i need? Can i buy from Amazon?

which ones are better....Whiteline or the SPL Solid ones?

Solid will transmit more vibration. I'd do poly on a street car.

Zspeed carries the whiteline bushings and pretty sure they have them in stock

Here is a video on how to replace it.

These guys have the whitelines for sale and plus whitelines are proven to hold up.

Link doesnt work

only lasted 30k miles? is the bushing defective?

Our cars have the darn period.

I just bought a set

I thought there was no fluid in bushings? they're just rubber...

They're fluid filled. This happens all the time.

thats what im trying to find out... bushing bad or something else?

Trust what everyone else has said already, that fluid you're seeing is from a busted bushing

I bought the Whiteline ones. In hindsight I should have bought SPL. But I don't care about NVH.

100% guaranteed to be a failed subframe bushing. Stop thinking about it.

thanks guys!

want to replace the fluid while I'm im at it... Red Line (50304) MT-90 75W-90 is this the correct one?

http://www.amazon.com/Red-Line-50304...=ATVPDKIKX0DER

I actually get the Redline 75W90 for the OEM VLSD because it is a GL-5 gear oil. The MT-90 you linked is a GL-4 gear oil.

Note that a GL-4 gear oil is recommended for the the 370Z manual transmission. MT-85 is the most commonly used fluid for the MT.

my car is manual transmission... so get this one...Red Line 57904 (75W90)

http://www.amazon.com/Red-Line-57904...=Redline+75W90

That's the stuff. Regarding the manual transmission fluid, I was just pointing out that the MT needs a GL-4 gear oil. The diff should get a GL-5 gear oil regardless of whether the car is AT or MT.

thanks for the help! :tiphat:

Make sure to use this one http://www.amazon.com/Red-Line-57904.../dp/B000CPCBF0 . Its the redline 75w-90 for your diff but is the GL-5 instead of the GL-4. GL-4 is fine in your transmission, but not in your diff as JARblue stated.

how much Quarts do i need to buy of the Red Line 57904 (75W90) ?

Expect to use about 1.5 bottles refilling the diff, so you'll need 2.

:tup: thanks bro!

Yep. I would also get a pump for the bottle because it makes life MUCH easier. Also be careful if you fill the diff while it is out of the car because you can overfill it.
