Hello Richard,
Thank you for this Information!
with a little cooling down, a beer in the evening and a bad night. I remember the move feels about caused on a short way, not as from a long way as from the halfshaft.
And as you say the bearings with rollerbearing and „Kegelrollenlager“ and this construction at the wheel/ brake and at the diff looks bombproof.
So on monday I‘ll undo the wheel and the brakedrum and will have a look deeper. So I‘m on the way to solve it myself and also in an area far under 1000,-EUR.
If I‘m wrong and it‘s the axle, my wife (she is well expierenced about my toys) had a deep look in my eyes and said: „ah, about 2000,-EUR? I was affraid about 10(thousend)“…
