I have a FX4 LS rear diferential. The rear end diferential has some oil spots at the left side.

The oil leak is very low, I can't see oil in the garage, only a large spot in half left of the diferential and also in the union witj the left shaft.

The dealer said they never seen before in 2004 and don't know what is happen without a close inspect.

Are there some with this problem?

Thanks!

 

Ive only seen one other post about a leaking differential, he took it to the dealer, they replaced the gasket...problem solved.

 

I had some leaks here and there on my rear-end. The seals went on it for some reason. Went into the dealer, had it fixed that same day.
