Hello, if I see this correctly, the sealing ring in the Diff case is leaking. Right? I found only one in the parts catalog that belongs there. Does this fit? 90222045 Repair is not the problem. How do you get the shaft out of the Diff without an accident? The recommended tool for KM-617 is not available. Unfortunately, there is also a hole in the gear-side cuff. I have read a lot here. Whenever someone tries to change the cuffs, Kurt recommends the following: the whole wave to change. Would I do, but the ones that are there are just as gummy or worse than mine. And cost 3x as much as two cuffs and have significantly more kilometers down. Is the joint pressed off SO hard? The gear side cuff can’t be changed separately, right? (except with such a glue cuff of course.) Can I get out beforehand whether I have Saginaw or Loebro? From SXXXXXX it seems to be Loebro, doesn’t it? You’ve got some leads!
