99 Honda Accord, 4 cyl. BAXA Trans.
It is well known that when the differential bearings start to go, the differential seals at the output shafts also start to leak and or blow out all together.
What is the reason the differential seals at the output shafts leak and or blow when differential bearings start to go? Turbulence? Heat?? I do not know the answer to this question but not knowing has got my curiosity up!
Does anyone know answer??

Thanks in advance!!

 

Misalignment. When the bearing begins to fail it no longer holds the differential on its original axis. The seal then leaks.

 

MAD MIKE has got knowledge LOL. Props to you mike :-)

 

That makes sense. I recently pulled my trans to send the input/counter shafts out to dave @ synchrotech and while pulling it noticed the seal on the intermediate shaft side was leaking. When I popped the casing off and took out the diff, I noticed the bearing on that side was bad too.

good question

 

Check your intermediate shaft to make sure it is not damaged in any way. If so replace it or you may have the same issue again. More often it is the passenger side bearing that goes first and eventually takes out the intermediate shaft side diff bearing.
