Open Diff
 

Does anyone have a complete open diff for a manual?

or know where i can get one?

bump!

Try looking on ebay, they might have one at a decent price.

I have it. Not the pumpkin, just the gears and axles. I see cases on eBay for $200.

Unless you know how to do the diff install correctly yourself I highly recommend you just buy the whole pumpkin.

Also, remember the G37 pumpkin will work as there are a lot more of those out there.

Ok, thanks, i'll check out G37's and Ebay.

why do you want an open diff??? ill ask my friend for you.... i think he still has his stock one laying around somewhere

Either because its a bit easier/cheaper to install a real diff, or he's gonna weld it closed

I still have it, ready to ship. Ring, pinion, gears and axles. PM sent.

i'm dealing with this shop that installed a quaife on my open diff, they botched the install. it's really whiny, it howls and clicks. he must have not set up the correct backlash on the gears.

so i'm suppose to take it back for a 3rd time next week. if he doesn't fix it, i hope i can get my money back. I think the pinion/ring gear are now damaged.

just give me some time to give them a chance to fix it. if he doesn't then i'll probably buy yours and start from scratch.

thanks for the responses, i'll let you guys know what happens, i hope they will cover any damaged parts.

thank you.

he said that he checked the clearances, and that they are all within spec the second time i took it in. he got new shims.
he thinks it's the quife it self, he's going to return it and get a new one.

so he now said the Quaife was ok and that the gears are to blame.
Now i'm worst than when i started, with an open diff making noises. :(

Im in the same situation with my current diff too. I had a shop install my Quaife LSD and my 4.08 gear swap. Got my first setup and everything seemed good. after about 400 miles it started to whine, took it back and they said the gears were trashed. Just installed another set of gears again with the Quaife and now the backlash is off and only whines on deceleration. Only 4 miles on it so taking it back to them tomorrow and no damage should be done. When I drained the fluid today for the swap, there were no metal shavings so thats a good sign. I did buy a donor diff to start though so my car hasn't had any down time as I still have the OEM one to swap in and out but 2 hours to swap each time and $60 worth of gear oil every swap is annoying. 1 more shot tomorrow and let's hope this is it for me.....

^did you have to pay for the second set of gears?
I should have started with a donor diff like you.

Unfortunately I am in the same boat on my Quaife install as well. My whine is only under acceleration however.

yeah, i had a whine on acceleration, now i also have a howling noise under heavy acceleration.
My installer called Quaife, and they told him that i should just install a catback exhaust so i didn't have to hear the noise! wtf?!

I have never heard about this with the quaife differentials. I was considering to get one but I think I may wait awhile after hearing all this from multiple people... hope everything works out with you guys.

i don't think it's the quaifes fault, its just the installation of the gears needs to be done correctly.

It might be Quaife's fault if by bolting it to the ring gear it causing a small amount of runout. I've read one thread on the 350z forum where this was the case.
On my car, the installer said no shims for the backlash were needed, even though he ordered them all just in case. So either he got the backlash wrong, which is the most likely, or there is other possible factors, like the runout.

They may be covered by Nissan Warranty but I need a VIN from a frontier with the 4.08 gears in it. I did pay for them out right though in order to get everything together and finished. Could takes weeks/months to find someone willing to let me use their vin.

Mine is all gear related. The quaife performed perfectly and with whining changing situations, even with the new gears that its clear its a gear issue and not the diff issue. Now the quaife sizing does vary from unit to unit which is what makes it so hard to shim. Their machining isnt identical everytime and as we all know, the mm's REALLY count when shimming.

OP, the howling noise is probably because the back lash isn't set correctly. Nothing to do with the Quaife diff. I had the same diff and 4.08 gears installed on my 350z. I had a slight howling noise above 80mph.

Faulty Quaife
 

Hi Guys. I just had a Quaife installed. It sounds like it was a faulty install. My Quaife has no noise . In fact they are probably some of the quietest Aftermarket LSD that you can install. Its a clutch less design.

yeah, that howling sounds like tires, but it's not.
i'm going to end up man, buying new gears. sucks! i hope i can buy some used ones. Not many people have used gears laying around!

matcop, i hope my quaife install will be noise free like yours soon!

bump

No longer need.
Please close this thread.
thank you.

My mechanic found the Pinion gear finally... oh.

too late! thanks.
