Where is the leak coming from: Fill plug, drain plug, diff flange or from between the diff and axle housing?

Hi,
Yes I have done that..... I removed it and blew down all seems OK.... noticed when I removed the pipe, the pipe has a 90' curve and just pushes in ? Is that right no connection or anything |

It should push into a pushfit fitting, and require the collar to be held in as pipe is pulled out.

The original fitting is a brass item that is pushed into the axle hole.
It’s explained here. https://gwynlewis4x4.co.uk/product/land-ro...-fittings/ |

Check the prop UJ’s right away, especially the one nearest the diff.
If they fail, or a bearing cup has failed, that can in turn cause the diff nose pinion oil seal to become oval and thus leak. And if oil can leak out, water can get in so until fixed try and avoid significant amounts of water such as Fords, river crossings, deep water etc. This is based on presumption, and bear in mind the UJ’s can be difficult to notice their failure unless unbolted. Mine went though servicing and MOT unnoticed at the time, I checked by taking it off and it was obvious, not so easy to tell whist bolted in situ though. Are the nipple / zerks there? When were they last greased out of interest?  ⭐️⭐️God Bless the USA 🇬🇧🇺🇸 ⭐️⭐️ |
