Help - Disposable diff syndrome. My 200Tdi is eating them

<< < (4/4)

CNorman:
Surelly a 24 spline diff would be tougher than a 10. Your meshing 24 parts of metal, not only 10!

extreme90:
no
he is siezing up the pins that the sun and planet wheels run on due to excessive wheelspin ect ect
then once nipped up, shaft breaks gubbings drop out  :lol:

this milarky about 24spline being stronger than 10 spline is aload of twoddle
only difference being the amount of splines are on the planet gears
the suns, pins, ring and pinion are all the same

go to hell with it, fit a ARB problems solved  :lol:
4 pin diff and a air locker all in one so you can go further than the rest can  ;)

Range Rover Blues:
Completely agree with Dan.  24 spline only gives a (slight) advantage in the streegth of the halfshaft and that comes at the expense of durability.

As you aren't busting half shafts yet then 24 splines is a red herring.

Fit a locker, any locker and you will stop the problem Dan is describing.

Thanks for all your advice guys. I've spoken to Steve at Crown diffs and he was very helpful. Just to get the truck back on the road I'm going for another 2nd hand one, hope for the best and take it real easy, take out some junk out of the back, throttle back the diesel pump, and reduce the "mental moments" to a bare minimum. In the meantime, i'll be saving my pennies and going for some sort of locker or a 4pin jobbie, so that when the next one breaks I can afford to do the job properly!

Re: the strength of axles, it wasnt just an off-the-cuff remark, i've got a link to a page (which annoyingly is on my work computer so I'll have to get tomorrow) which states that the 10 spline can take x amount of 1,000s of Nm, whereas the 24 spline was re-designed and can take x ++ amount of 1,000s of Nm because of the extra material in contact with the halfshaft. Of course, the information is only as reliable as the source, but it would seem rather far fetched to fabricate truth to that level of detail.

Steve, I'd be interested to read that if you can find the link.  The only part that is different is the centre of the sun gear within the diff and the end of the halfshaft, which is the part that brakes.  Typically the root of the splines starts to twist then snaps.  I guess that because the 24 splines are not as deep that there is more metal at the OD of the shaft where most of the strees is, in theory you could say it's stronger but they may also be heat-treated like the 10 spline units that Ashcroft's used to sell (I'd have those if they still made them).

The downside with 24 splines, now that they are starting to wear is beacues they have am angular contact face rather than a square one, once they have worn they jump, both the gear and the halfshaft are then wrecked.  Whilst 10 splines do wear it really just weakens the shaft as there's less metal in it, plus is causes backlash which is very annoying as I know first-hand (my diffs need to go to Crown soon).
