When me car is up in High MPH i got a film of diff oil over the back of my car. Suppose this could be cos i have over filled it maybe? If so what the best way to get it at the right level of oil when its on the car, and if its not over filled where would it leak from?

 

If the diff is at the wrong level.Just undo the filling nut and wait.When no more comes out it is right.Make sure car is on flat road.As the level is the bolt hole.

You sure it diff oil

 

Yeah deffo diff oil as u can smell it, Though how can i undo the nut on a level surface when i got to jack the car up to get to it? doh

maybe try and get under there tomorrow now its higher

 

Either Jack the front up the same as rear or find a friendly garage who will borrow you a ramp for 5 mins.

 

Need to do it over a pit or drive on/4 poster ramp if u want it really flat

Should be easy to spot if its leaking from diff once you get under there

 

Job to do on Friday i think no where can i find a nice ramp

 

Could be gearbox oil?

Did you take complete engine/box out when you had rebuild or split engine off box
in car?????

 

Nah split engine and box mate, im sure its the diff as it smells like it, and i got a bit of oil on the floor at rear of garge. Hmm best get it checked as wouldnt want that to run out of oil

 

Ahhh,if you've got puddle at rear must be diff

4 places it could leak,input seal on front,driveshaft seals(1 either side),
or rear cover(very unlikely)

Unless when the car was so low you've worn/cracked the bottom of diff casing.................looking on the bright side

 

dont joke mate i have grouns some of my case on the diff at the back

But to be honest it looks like its coming from further up after quick look. Will clean it off and go from there i suppose
