Here you can take a look on the different shafts.

The 500's shafts are also shorter than the 126's ones.

Good to see you got it sorted. The advice on this forum is invaluable.

Here's a real coupling problem for you.

The bloody shaft on mine wore and not the coupling. Need to find out how this happenned so it doesnt happen again.

Any ideas anyone???

Thanks!

Wow, nasty wear on those splines. It's good that you posted that up because I was wondering whether I should replace my drive shafts..

Oh dear... I have suddenly got the same problem. there was no warning at all but at least it was on the way down my drive!

Back to the Manual and time to learn something new... I have absolutely no idea about this part of the car!

Hi Abiella,

It happens when the couplings come loose or arent tightened enough. Its a common mistake made by not wanting to tighten the couplings for fear of threading the alloy. I used a removable loctite when I put mine back together and it seems to be fine 3000klms later.

Fixing it is pretty straight forward just be mindful of the shims that fit on the axle. Make sure they are facing the right way and the right side. When I dismantled the gearbox, I took care not to pull the axles out until the entire diff assy was apart
