zelda Posted November 3, 2018 Share Posted November 3, 2018 (edited) Hi guys, I've just opened my new Quaife LSD and inside the box there's some instructions showing that the shafts need to be cut down. (Image attached) Anyone know if this 100% required for all 350z models? Mine's a UK 05 plate DE with a viscous LSD. Bit annoying if it is as this was supposed to be direct fitment. I thought that was the point of specifically selecting a replacement for the viscous unit. I guess though I won't know until it's all pulled apart. Also, I've got replacement seals, bearings and whiteline bushes but my kit didn't come with: 1 X Nissan OEM Inner "Back" Pinion Gear Bearing 1 X Nissan OEM Pinion Crush Sleeve 1 X Nissan OEM Outer "Front" Pinion Gear Bearing 1 X Nissan OEM Pinion Oil Seal Are these extras a requirement? E.g. likely to get damages upon removal. Thanks Edited November 3, 2018 by zelda Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted November 3, 2018 Share Posted November 3, 2018 Best to use a Nissan short shaft as cutting is not a good plan. You will only have to replace the parts you have listed if you are removing the pinion shaft. All the above in stock if required. Quote Link to comment Share on other sites More sharing options...
zelda Posted November 3, 2018 Author Share Posted November 3, 2018 Is the Nissan short shaft something that I might have installed stock already? What's the price and delivery time? Quote Link to comment Share on other sites More sharing options...

As Alex has said cutting down may not be easy or pleasant but you've got nothing to lose giving it a go if you have time if it doesn't go to plan If you're not changing final drive and just swapping crown wheel to the new diff you probably wont have to adjust the pinion shaft at all but still check the toe/heel contact and backlash after install 2 hours ago, zelda said: Is the Nissan short shaft something that I might have installed stock already? What's the price and delivery time? I think the non lsd import models had this shorter shaft fitted from factory so all UK cars with the viscous LSD's will have the longer shaft installed. Hope it goes well for you! Quote Link to comment Share on other sites More sharing options...

And yeah, I should have known nothing is bolt on. Happened time and time again. Lol I just could do without the additional expense at the moment so I will probably try machining them and see how I get on.. doing LSD, clutch, flywheel, plenum spacer, airbox mod and lightened pulleys all together is racking up.

andy james Posted November 3, 2018 Share Posted November 3, 2018 I'm in the process of building a Quaife. If you have the Standard OEM diff you will have a short shaft on the LH side and a long one on the right. Alex supplied me with another short one. The early cars without the Viscous diff have two long shafts. Yes you can cut the long one down but as Alex says it's not advisable as there will be a reduced amount of spline left compared to the short one and also no groove for the Circlip which holds the stub shaft into the diff. My advise is to get another short one. 1 Quote Link to comment Share on other sites More sharing options...
andy james Posted November 3, 2018 Share Posted November 3, 2018 This shows all the 3 types of output shafts. Quote Link to comment Share on other sites More sharing options...
350Butcher Posted November 3, 2018 Share Posted November 3, 2018 looks like I’m a little rusty on axle advise. Apologies. Its the flat tip short axle pictured on the far right you’d need. Quote Link to comment Share on other sites More sharing options...
