Brand new ball joints only a couple thousand KM's ago (Ball Joint LEMFÖRDER 13307 01)

So I've managed to gently tap the stump back in with the output shaft remaining intact.

No dramas at all with the wheels turning the diff properly on both sides before I even started to tap it back.

I didn't hear any click due the noise from tapping but it's properly home and doesn't appear to want to come back out that easily even when prying with a bar.

I'll refill with gear oil today and check for leaks.

I can't hear any bad noises from the diff when I turn the wheels by hand so I don't think there is a C clip floating around to do damage.

Looking at how I'd even inspect, the whole diff would have to come out and that's more than I can do at the moment.

Hopefully it's all good!
