This is probably a dumb question for some, but nonetheless I don't know the answer...

If I remove my Quaife LSD for a few days, will the car still drive? I know an open diff car like the base model Z doesn't have an LSD, but I am wondering if removing my LSD will make it an open diff car or will it make it immobile?

The reason I ask is, I have to send my Quaife in for some warranty work and it will be gone for a few days. If I take it to a shop to have it un-installed I would need to be able to drive it home, and then back to the shop for re-installation.

Thanks in advance for any help.

 

I'm not sure about the main question, but I recently changed my rear pumpkin and have my original 3.3 open if you need to borrow one. The shop would need to do a couple of component transfers to make it work for the Z but that's an option if you need it.

 

Thanks man, but VRT should still have my old VLSD laying around as well. I am trying to see if I can avoid that shipping and extra labor first. How's your mean *** FX doing?

 

FX is all good, you gonna be at Irwindale on the 27th? Let me know if you need the pumpkin. The only thing needed to change is the companion flange for the driveshaft since the G/Z is different with my FX.

 

from what you are saying,as long as you replace the pumpkin,it dosent matter if its a open diff or not.the car dosent know only you do.

 

rookie - Yeah I will be there so long as I get this diff problem fixed. The Quaife is only putting power to one wheel for some reason and that doesn't do well for drifting. Good news is Quaife says its only a 3 day turnaround. I want to have it mailed out by Tuesday though, just to be safe. If for some reason it will take longer, I may have VRT overnight me a Nismo or something for the event.

 

I don't have another pumpkin though. I would literally only be removing the Quaife from the current pumpkin.

 

Where are you getting it swapped at? I've been thinking about putting my 3.3 back in so I'd have a 3.5 lying around. Or you could just borrow my 3.3 for a week.

 

The same shop that Rob had his installed. Thanks Ty! Thats good to know that I can borrow yours if needed. If you decide to put your 3.3 back in, I know someone who will buy your 3.5.

 

You cannot do this. The drive shaft turns the pinion, the pinion gear turns the ring gear. The ring gear is bolted to the differential. The differential turns the axles. Take out any one part in this chain and you have a non working vehicle.

 

Thanks! Ty, I need to borrow your 3.3 pumpkin

 

As 350Zteve pointed out, the differential is what drives the axles from the ring gear. If VRT were to overnight you a Nismo, you'd have to replace the axle stubs as well. Same if you went to put your original VLSD back in.

Cheapest and easiest option, and it looks like you're going that way, is to use roneski's backup pumpkin because then its just a several hour swap. I had wanted to keep my original pumpkin as a backup just for the just for a situation like yours, but it didn't work that way when I did my 3.9/Quaife install.

BTW, any idea what caused your Quaife to need repair?

 

Also keep in mind you cannot just simply put another differential in. The install of a differential requires special tools to measure the backlash thrust movement of the ring gear teeth to pinion teeth alingment. Mess that up and you ruin the gears.

 

helldorado - I have no clue what went wrong with the diff. Maybe excessive heat?

350Zteve - I will be having a professional shop do the un-install / re-install.

 

Just get a rental man, it will be alot cheaper

 

Thats not the issue. The Z is not my daily driver. I was trying to get some sort of LSD in there so I could go to the 350Z/G35 Drift Event at the end of the month. The shop wont let me keep the car there either.

 

This is why you dont see Quaife's in rear wheel drive race cars making over 250hp....nothing but problems.

 

do u guys happen to have a stock vlsd for sale? i have a base model and i need an lsd lol thanks

 

Just to clarify, was there a defect with the Quaife, or has it always had this problem? A Quaife definately applies power to both wheels, and the appropriate level to maintain equal grip. With perfect grip in a straight line, you will have a 50/50 power split between left and right sides.

You are correct, in that most drifters prefer a full locking 2 way clutch style diff, becuase it tends to give better ****-end control when you are at radical angles. But lots of circuit racers love using the Quiafe on a road circuit.

 

Don't get me wrong, I love the Quaife, and it would be awesome for drifting. This is a new problem and basically the car acts like an open diff car. I recieved a new Quaife LSD in the mail yesterday
