- I bought a 350z differential with aftermarket Central20 3.916 final drive gears. To make it work on my G37, I need to swap the stub axles. I also went ahead and installed Z1 bushings and Z1 diff cover.
What happens if you don’t swap the stubs? I have a 350z hr with a m/t. I want to put the 370 nismo 3.9 differential in
Joseph Rizzo , thanks for checking in on the video.
I believe the sensor is for your rear speeds, and also for abs and vdc. If you want to delete your abs and vdc then you won’t need to swap it.
ProjectPanda13 okay thanks, I don’t have vdc or traction control but I do have abs
Omg finally the video I’ve been looking for. This was so much help
Thanks for the support. Very glad it was helpful.
Supporting your channel!! Great video!
Z-speed , I really appreciate it.
So, the portion of the shaft that goes inside the assembly is identical as far as size, threats, etc is concerned between one out of a 350Z and one out of a G37, but it’s only the number of teeth on the outside that differs, hence why they can be swapped? I ask because I have a 2004 350Z and just took possession of a differential out of a 2008 G37 and am debating whether or not to swap these flanges / stub axles. Thanks.
Thanks the view.
Yes, both are the same length given that both are VLSD or both are open. pops out and goes in the same.
ProjectPanda13 ok thanks.
ProjectPanda13 is it an optical illusion or does the shaft of the stub axle seem longer/shorter in one compared to the other? Are they different lengths based on side (passenger side vs driver side) or G35 vs G37? Ref. min 7:15
Yea, they are different lengths. I believe even the open diffs are like this.
Hey what’s up. I got a 2007 G35 sedan. Took differential out. And I want to put in a 370Z 6spd VLSD got it used. But In order to make it work in the G35 I have to
•1-pop the stub axles on both diffs so we can swap them case
G35 axle Stubs to 370Z diff (new diff)
•2 - take off the G35 3 bolt flange and and put it on the 370Z Diff because the 370Z has a 4 bolt flange.
•3 - cut shaft where 3 bold flange bolts in to so it will fit drivetrain right. Has to be cut about 1 inch 3/8ths. That’s is what I have read on some forum. And seeing ur vid
Bam Bam , thanks for checking my video out.
1 - correct, The stub axles is because of the teeth count for the sensor
2 - correct, automatics had 3 bolts flanges while manuals had 4.
3 - I am not sure on this part. Since my swap was from a manual to manual. I’ll do some searching to see what I find also
Thank you I will really appreciate that if I can get a confirmation on the cutting the shaft
I have a 03 g35 sedan automatic can I just swap a 08 or 07 g35 sedan automatic diff to it?
Thanks for checking in on my video.
Yes, you can swap an auto 07/08 g35 into your car. You will have to swap the stub axle also unless you don’t need the sensor.
@@ProjectPanda13 okay thanks for the fast response!
What year g37?
I have a 2010
Sick video bro 🙏🏽
Bryan Bellaco thanks for the support
So just to clarify, you used the 350z LSD diff. You installed the G37 non-LSD stub axels into the 350z LSD? I’m curious because as a understand you would need VLSD long stub axels from a VLSD g37. I guess using non-vlsd stubs worked for you?
My G37 diff was vlsd also. Your understanding is correct that only vlsd work with vlsd.
Do I have to do anything if I want to throw in a 2014 G37 LSD diff into my 2011 370z because my current diff is open diff
Just make sure the g37 diff has the same input flange to match your 370z. 4 bolt is manual and 3 bolt for auto.
Everything else is a direct fit.
it was helpful!
I’ve got a mt g37 drift build and I was thinking about swapping my diff for a 350 only because 2nd gear runs off limiter and 3rd gear bogs, with the 350 diff would you say the gearing feels longer or shorter?
the manual 350z has a final drive of 3.5, the auto 350z is 3.4. you manual g37 is 3.6 final drive ratio. both 350z FD are longer gearing than your manual g37.
mine is unique because I got my 350z diff with aftermarket gearing at 3.9 for a shorter FD
So you used the 350Z pumpkin and swapped the g37 stub axels? Did you change the sleeves and side bearings aswell? And did you swap the cable hook ups for of your original diff?
Chris Saunders , thanks for checking out the video.
I used the 350z pumpkin swapped the stub axles and sensors. I didn’t touch the sleeves and side bearings .
It’s been holding up very well, no odd noise, vibration or sensors acting up.
Does anyone!!! Know if after taking the differential cover off allows you to see a gasket!??? I need to replace bearings and seals but Idk if my g37 coupe has a gasket in between the diff cover and the actual diff PLEASE help !
Juan Galvan , I don’t remember seeing any gaskets with the cover off, only the ring and top of the bearing bolts.
god damn thank god you made this i swear i wasnt able to find anyone wlse dooing this thank you so much!
Glad the video was helpful.
Did you leave the diff oil in while you were removing the output shafts or did you already drain it? I'm about to remove mine but want to make sure it doesn't need any oil in it to remove
The oil was still in the diff when I removed the output shafts. I changed the oil afterwards when I swapped the diff cover.
Those teeth are for traction control why does it matter if they match ? #racecar
I still need my training wheels. I agree though, doesn’t need to be swapped is that’s isn’t a concern.
Bro you never did a video explaining the differences you felt. I know it had to have been noticeable. Going from a 3.5 (I think that’s what you said was the old one) to a 3.9. You should feel the difference plus’s the much sharper and responsive torque transfer to the rear wheels because you did the bushings too.
Thanks for the idea. For some reason I completely to make a review/explanation video.
I’ll be sure to put one together. There is for sure a difference in acceleration. Each gear rpm was raised about 500 rpm or so for the same given speed.
I have more power at certain rpm that I don’t need to downshift anymore at specific speeds.
It’s the perfect compromise for acceleration and top end speed.
@@ProjectPanda13 that’s awesome! I’m doing the 3.9 ring and pinion this week. And all the diff bushings too just like you. I can’t wait to install it and feel the difference.
@@yusefkabib2073 , you’ll enjoy it. The 4.08 is nice but some find the 3.9 to be the best and not overly aggressive
I got a 3.69 2008 g37 diff w/o the stubs thinking I could swap stubs from '03 g but I couldn't get them to fit. Guess I got the wrong one?
Paul Molina , I believe they should still fit. It should only be the ring tone that is different. And it’s the correct side for each?
@@ProjectPanda13 so I found that mine is an open diff with stub lengths different from vlsd. junker refuses to sell them with carrier assembly so til I decide I returned the 3.69 and imma weld the old open 3.53.
Oh dam. What is the purpose you have for you car? Sounds like drifting since your welding it or maybe for drag?
How many liters of oil do you used bro ? 2 right
Bryan Bellaco , for the Z1diff cover, yes, a total of 2 liters.
ProjectPanda13 thanks bro
What would I have to do to make a 350z Hr open diff to fit a g37 with VSLD
thanks for stopping in on this video.
the physical diff itself will install directly into your g37. But the ring tone gears on the stub axles have a different count on the 350z vs your g37. if you want your sensor to read correctly, you need to swap the stub axles from your g37 to the 350z diff.
But your g37 is VLSD, the stub axles are different than an open diff stub axles. you need to find a se tof open diff stub axles form a g37/370z and install those into that 350z diff
are you doing this for the gearing?
@@ProjectPanda13 yes I am thank you for replying my friend was about to give me his open diff and they look identical but I was watching your video then I realized they’re not the same
@@OtherCoder6 , it’s only the teeth count on the ring tone that’s the important thing. If you find the stub axles for open diff it can work
Will the axles still line up with a open diff to vlsd
Hey can the flange be swap cuz I got a 04 automatic g35 and want to install a 08 g35 but they say my flange is different
King David , thanks for the support.
From what I understand, the flanges differ between years only due to using bolt and nut to tie the flange to axle vs just a bolt that threads into the axle.
Also make sure your stub axles are either open or VLSD. The two are different.
@@ProjectPanda13 hey dose oil sopost to come out when removing those 2 parts
King David , no fluid should come out, only if you turn it over on it’s side. Maybe if it was over filled it could come out possibly
@@ProjectPanda13 is cuz I wanna gonna buy a differential from a guy but the car got in a wreck and one of those parts you took out was out on this one and the differential had oil all over it so I'm guessing that differential was screwed
Best way to tell is to open the cover, spin the center and check on the gears for damage. It’s ok if gear oil cane out.
Thanks for the video. Got the Diff out and have been looking at how to get those side bushings out. This answered it all for me!
James Stephens , thanks for the support and checking it out. I’m glad it helped.
@@ProjectPanda13 By the way, finding a 34mm socket is not so easy. Home Depot - no, Harbor Freight - no, NAPA store - Yes! The 32mm is no problem and then it seems to jump up to 35mm at most places.
Lol, 34mm becoming the next 10mm . I think 35mm would also work. Did you already get this done?
I used a 36mm. Worked great on both sides. Got it at Home Depot for $12.
@@Gryde35 Will a 36 mm socket work on g35 pumpkin? Also do I have to buy an impact socket ??
That music is creepy. I had been looking at pics of biohazard cars before this. It's kind of a messed up night.
brad h , lol, I can definitely see this music in the background for things like that.
