Signs Of Diff Oil Leak

[dmosconi]

Hi All,

Went for a fairly long drive on Saturday, when it reached 40Deg, was not pushing the car much only every so often to overtake.

So I get home that arvo and left the car for a hour or so then went to go out to the shops, as I was backing out the drive I notice a few spots on the carport floor, so I get out give it a rub then a smell, farkin diff oil. I get the ramps out back her onto them get underneath and can’t find any signs of a leak, so I clean up the oil and off I go.

Any way get home yesterday and move the car to give it a wash and fark me the oil spots are there again, almost clear oil with some spots darker than others, so out come the stands up she goes again and nothing to be seen, smells like diff oil just no signs of residue anywhere but the floor, its got me stumped.

So today I went for a test drive and could hear a slight rubbing noise echoing from underneath the car when just rolling with a wall beside the car, so I come home to investigate, get out of the car and can now smell burning oil, up she goes and there’s farkin nothing there, I can see it on the floor, now smell it burning but can’t see a thing.

Any offers of advice would be appreciated.

Check the breather. Early BA models had some issues with the drive shaft seals leaking but I believe that was resolved.

Yer I didn't mention its a 06 BF with an auto 6speed box.

One of the seals, either from drive shaft to diff, or one of the seals from the diff to cv shafts. I recently had my diff rebuilt and about a month later noticed spots on the driveway.

Apparently when putting it back together the seal for one of the cv shafts fell in slightly causing the leak. Thank god for warranty as it's a big job due to having to drop the whole rear.

I recently had Ford do warranty on the rear end of the car, they replaced all the bushes and stub axels both sides, would this work cause something like that to happen? It’s only been 6-7 weeks since getting the car back. If so, I agree it's a big job, TFG I've still got an extended warranty.

I’ve been underneath the car for a thorough look with flood light, found oil around, but I still can’t find exactly were its coming from.
