Thread: Swapping 10-spline for 24-spline axles worh it?

I can't answer the question, but I wondered if you still have the gearbox out of the car? My son's car has just done it's second one.

Sorry, everything else went, only things I have left are mirrors, seats and some bits that are compatible with my 2 rangies and being kept as spares. and the chassis which is now a farm trailer.

there stronger, but in no sence strong fit and forget, if you busted a diff b4 it wont take much more punishment to brake a 24 diff,

I wouldn't bother swapping if there's nothing wrong with the 10 splines unless you go to lockers. If you go to lockers you,LL probably better getting to toughened axels and cvs

Having broken a diff a few years back, and being in the habit of solo remote trips, I am very wary of breaking a diff or axle and stranding myself. May upgrade to a locker at some stage also.

The diffs are basically the same , it is the axles that are stronger so if you broke a diff before you are just as likely to.
The axles are larger diameter and are stronger.
Lockers break axles usually, so I would ( and did long ago) fit Jacmacs or other stronger ones.
Broken diffs are IMHO and experience from different resons to broken axles.Diffs usually fail from excessive wheelspin starving the spider gear shaft of oil, it picking up and spitting the circlip and then falling out into the case, or variations thereof.
So diffs usually fail from overenthusiasm, axles from a sudden stop which snaps them from the inertia of the drivetrain torsion twisting them beyond their elastic limit.

Hi Pod

I would determine the need to change your diff assemblies, by checking for the amount of wear or movement through the axles and sun gears, etc.

Use a measurement in the form of degrees of a circle or position of the hour hand on a clock dial, on the free side.

If the old assemblies have a lot of slop, when you rock one of the wheels back and forward, compare that then with your spares.

To do this test successfully, you will need to prevent the pinion spinning by locking it tight and also the other side, wheel or axle.

Thanks for the replies; nothing wrong with the existing diffs so would only be doing a swap for the sake of fitting something stronger. Given the above advice, I won't bother changing the axles out in favour of the 24-spline units, might even put them on the market to fund a locker and tougher axles.
