Quaife ATB Front Splines

Hi,

I would like to fit a Quaife ATB to the front diff on my Gen 4 (and rear). My question relates to the number of splines I should specify for the front Quaife ATB, OEM 22 or 26? From what I understand the standard front half shafts should be fine, and if ever not then HD 22-spline aftermarket ones could be considered, so am I correct that there seems no good reason to go for a 26-spline and all the extra bits/expense upfront?

Thanks very much!

It all depends how hard you intend to push it off road 
26 spline shafts will be stronger 
But I'm sure both 22 and 26 spline use the same cv joint

Surely the idea of having a locking diff is to stop the chance of having a spinning wheel in the air situation that can snap a shaft when tyre and earth re-unite.

Rodger you would be surprised how easy it is to lift a wheel in certain situations. Then there is bouncing on the spot on up hill climbs. 
Like Lambert says  (mechanical sympathy)
Also having really low gearing plays I big part 
 

If the suspension is capable of maintaining traction to all the wheels that are driven, then there is no need to add any form of traction control, but as Wild Bill wants to add Quaife Automatic Torque Biasing diffs to his Jimny I assumed that he periodically lifted a wheel and needed the Quaifes to control the inevitable spin out that will result. If you drive a track you will inevitably lift a wheel but Quaifes and the like will control the spin out so that when the wheel drops back it will not be spinning widely but will be controlled so that the damage you mention should not occur.

Yes, Roger, that's my thinking as well that I am trying to confirm. That coupled with the ALLGRIP Brake LSD Traction Control already there.

Thanks for your reply.

Yes, I did some reading on driving with the Torsen diffs used in military HMMWVs, and I believe I now understand the difference between Brake Throttle Modulation as used in them compared to the on-off ABS traction control on the Jimny. It seems to me that if there is a wheel in the air spinning that when the ABS brakes that wheel the ATB will indeed send torque to the other wheel, but when the ABS braking ends, if still in the air, the wheel will begin to spin again and torque will be lost to the other wheel again and we begin again, whereas with BTM the brakes remain gently applied together with the throttle (robbing some torque of course but better than 0:100) until both wheels are on the ground and there is at least some traction on both.

This leads me to wonder if anyone now has any longer-term experience using the Chinese LR/WMD E-Lockers + Torsen diffs where you should have the benefit of Torsen on the road and fully lockable diffs when desired (I understand that there is some wheel movement required in the locking mechanism of an E-Locker before it actually locks compared to Air Locker, especially if changing vehicle direction).

Anyone?
