nissanman312 Posted January 8, 2016 Share Posted January 8, 2016 I'm wondering if anyone can clear this up I've spoken with quafie today regarding fitting there diff to the 370z The chap on the phone was helpfull but wasn't sure if the 370z would except the diff as a straight swap I have the 370z gt I assumed this has the vlsd I know when fitting the Quaife to the 370z auto some shafts from the 350 are needed But thought I'd read it went straight in the vlsd pumpkin on the manual 370z Can anyone clear this up This is what Quaife sent me regarding the 350z Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted January 8, 2016 Share Posted January 8, 2016 Fitting a Quaife into any Viscous Nissan LSD needs the above preparation. Think difference between 50 and 70Z is a very slight final drive difference Quote Link to comment Share on other sites More sharing options...
Adrian@TORQEN Posted January 8, 2016 Share Posted January 8, 2016 (edited) Quaife Differentials require no modification to install in a Base model vehicle with open style factory diff. However if your car is equipped with a factory LSD you have two possible options to properly install an aftermarket Limited Slip Differential: A. Purchase a Base Model LSD and add the optional Stub Shaft assembly B. Purchase the Factory LSD Model Differential and DO NOT purchase the Stub Shaft assembly, this will require the long stub shaft to be machined. Please note: Both versions of the Quaife Differentail are identical in operation and specifications. http://www.the370z.c...d-question.html Edited January 8, 2016 by octet@TORQEN Quote Link to comment Share on other sites More sharing options...
Bodyboarder81 Posted January 8, 2016 Share Posted January 8, 2016 So looks like you cut one shaft by 1.7 and jobs all good Quote Link to comment Share on other sites More sharing options...

Mark@Abbey m/s Posted January 8, 2016 Share Posted January 8, 2016 (edited) All UK 370Z have Viscous LSD I think. I think the shaft is the same as a 350Z Nick I can send you a machined shaft and you can send your un-machined shaft back; I have a few spare 350Z LSD units in stock Edited January 8, 2016 by Mark@Abbey m/s 1 Quote Link to comment Share on other sites More sharing options...

Bodyboarder81 Posted January 8, 2016 Share Posted January 8, 2016 Worth doing the diff bushes at the same time i guess ? Quote Link to comment Share on other sites More sharing options...
Richf Posted January 8, 2016 Share Posted January 8, 2016 Worth doing the diff bushes at the same time i guess ? I think so , at least have them in case the old ones are goosed as it makes sense, I have them (Whiteline not the cheaper ones) , the 350z half shafts as mine is an auto and a NISMO finned diff cover waiting to go on mine when I do the diff Quote Link to comment Share on other sites More sharing options...
Richf Posted January 8, 2016 Share Posted January 8, 2016 Base model 370'z are usually open diff , the GT has the VLSD, not many base models about Quote Link to comment Share on other sites More sharing options...

Richf Posted January 9, 2016 Share Posted January 9, 2016 (edited) mark is the new oem bearing kit necessary ? Depends on if there are bearings on the shafts or not , you normally press the new bearing on , you shouldnt really reuse the old ones Edited January 9, 2016 by Richf Quote Link to comment Share on other sites More sharing options...
dajw Posted January 9, 2016 Share Posted January 9, 2016 If you've got the VLSD and Auto, this is the one combo that you can't just fit without additional work and parts. Jez at Horsham Dev sorted mine out. Needed new half shafts from a 350z non VLSD.

dajw Posted January 9, 2016 Share Posted January 9, 2016 It was not possible to cut the shafts down to length, as some have suggested. There are some retaining clip rings that just don't engage when this is done (ask me how I know... In other news I have some lovely half-shaft door stops!) Not everything is required in the fitting kit that I purchased. I think they used only the seals. I still have the pinion carrier bearings.

dajw Posted January 9, 2016 Share Posted January 9, 2016 Sorry - I'll clarify that: it was not possible to cut the shafts down from my car. It may be possible with others. However it was not expensive to buy new ones that fit perfectly. Quote Link to comment Share on other sites More sharing options...

nissanman312 Posted January 10, 2016 Author Share Posted January 10, 2016 So you need a shafts from a 350 rather than cutting shafts down Quote Link to comment Share on other sites More sharing options...
Richf Posted January 10, 2016 Share Posted January 10, 2016 So you need a shafts from a 350 rather than cutting shafts down I believe for the auto its a better fit than cutting the stock ones down , dunno for the manual Quote Link to comment Share on other sites More sharing options...
dajw Posted January 10, 2016 Share Posted January 10, 2016 Yes, you need a set of Nissan part number: 38220-AR010 (for non LSD) one for each side, plus some bolts as the 350 is bolt + nuts and the 370 is threaded holes. Quote Link to comment Share on other sites More sharing options...
dajw Posted January 10, 2016 Share Posted January 10, 2016 So you need a shafts from a 350 rather than cutting shafts down I believe for the auto its a better fit than cutting the stock ones down , dunno for the manual If by better fit you mean "doesn't just fall out because it's not retained" then yes, you need the part. That's what happened when the cutting option was tried. Quote Link to comment Share on other sites More sharing options...

Machining isn't the same as cutting the standard shafts can be machined as per Abbeys info Quote Link to comment Share on other sites More sharing options...
