Re: My BW35 has got a serious problem
You're absolutely correct about the second shaft. That would have snapped very soon.
If you change the diff carrier bearings then you're probably going to have to reset the crownwheel/pinion backlash and the running clearance in the casing, so personally I'd closely examine the bearings, and if there aren't any visible faults, re-use them. I've never had problems with those. Same goes for the output shaft bearings, they're not prone to problems, and they can be turned in your hand to feel any rough spots, but the good thing with those is that changing them doesn't require any setting up afterwards.
No problem.
There is a pawl on the output shaft of the BW35 that holds the car and stops it from rolling in PARK, if the diff is broken as in your case, and you drive through the box (so you see the speedo working) and then put it in PARK, then the rotating output shaft snaps the end of the pawl.

Barten said:Whether I shall change both the diff bearing is questionable, I think when I have it all open, I 'll do it as a precaution. The shaft bearings I will definitely change. The one on the broken side was not good.

Barten said:But I will leave the rest of it as is. Your diagnose was very correct though, and saved me a lot of trouble. I could have been dismantling the BW35 now if it was not for your advise. Thanks!
No problem.
Barten said:There was one thing I did not understand in your second post to me : "and so don't put it in PARK otherwise you'll snap the pawl off"
What is the pawl? I did put it in park before that post, so what could have happened?
