Quaife LSD question

conmam · 04-03-2015, 11:24 AM

Here is the final cut version. Yes, cut exactly 1.700 inches. So, the final shaft length should be very close to 3.3 inches. Took me 45 minutes to do all this. Beats spending $160.00 on the new short shaft. Getting ready to bring this diff assembly for professional installation and adjustment.

Hopefully the final product will be nice and flawless. Will keep updating as I go along.

Now, I got to work on my 2014 Maserati Gran tourismo headers replacement..... Man these are real, real expensive.

Well, the project is done. Quaife is properly installed and calibrated inside the differential case with all new bearings, spacer and seals along with the Whiteline diff bushing set. After 1200 miles of driving normal to semi hard so far ( No track yet ), this is my opinion :

1) Very quiet. I do not hear any additional noise from the Quaife itself at all
2) The Whiteline rear diff bushings really put the wheel to the ground. Again, I do not feel any noise increase.
3) Much better manual traction control ( VDC off) during hard turns when 1 wheel started slipping.

So overall, as long as you install the unit and adjust everything to Nissan specs, you shall have a real reliable and sticky back end. Don't forget to torque all of the relevant bolts and nuts to specs after installing the diff assembly into the vehicle, or there will be future issues.

Anyone know the Nissan specs to install the quaife? Besides measuring the backlash, what are the Torque specs for anything inside the diff?

This cut was very easy and quick! Thanks for the help. Been running it all year so far issue free on a new Wavetrac

Regardless of the LSD you will be installing, you need to do the following:

1. torque all the nuts on the final drive according to torque spec in the FSM
2. check backlash to be in spec with the FSM specification
3. check preload (how much effort is necessary to actually move the gears within the diff), again, according to the FSM.
4. add oil with spec as specified by the LSD maker, amount specified by the FSM
