I have no idea if you should be able to blow pressure into the diff at all??
Anybody know?
Reading the manual for the diff it shows there is a 90 degree fitting that goes on top of the diff and is described as "breather tube and cap" items 34 & 35.
Would either of these be likely to block?
As my back is damn tender at the moment the last thing I feel like doing is crawling about underneath and pulling access cover off etc.

Unlikely to block in my view, you should not be able to blow through this breather as this would indicate air is getting past the diff output seals. The 90 deg bend would stop any diff oil travelling up the tube.Quote:

It will be clear.Block the end of a meter of tube and blow into it and compare.The D4 diff is a pretty small volume.Quote:

I have come across them blocked,usually a mixture of dirt and oil from what i have seen,or a wasps nest.
We used to find them blocked often on the work vans,but they have a very short breather.
If the diff was on a vacuum when we went to change the oil,as it had cooled down,that was the indicator the breather was blocked.
The diff seals never leaked.
