Default Rer diff leak. Pic included!

Hello. Only have 50 000km on my car. I noticed that 1/4 of the rear diff outside is covered in gear box fluid. It seems to be leaking. It doesn't leak on the floor, but when I run my finger on the rear diff, I can feel a layer of fluid. Like i said, it doesn't leak on the floor, like some cars leak oil. Just leaks very slowly I think, dries up from outside and on and on. Is that normal?? If not, can this be covered by warranty?? Thanks...

Just got picture up...!!!!

Are you sure it's leaking? cause at 50k kms, you should have recently changed the rear diff oil......

I know when I changed mine and with the rear diff skid plate, it was messy.....

I suggest to clean it off.... and monitor it....

Who changed the fluid last time?

How much torque was used? I think the torque required is 44 ft/lbs....

How anyone had this problem before if the gasket is leaking?

When did you do the fluid change?
Looks to me the plugs are not in deep enough. But need a closer picture to tell.
For now, use some Simple Green and clean the differential up, and see if the "leak" reappears.

Plugs are not leaking. The top part on the left is leaking. Could be axel or something. Made an appointment at the dealer next week. They will take a look..

It's probably actually the vent on top of the diff doing the leaking... it's a classic issue that there is a TSB on (though I don't have the TSB number off the top of my head ).

I hereby resurrect this thread!

I have a leak in my rear differetial (98 2.5 GT). Noticed it today while getting a heat shield removed. I looked up part numers to determine what the price would be to fix, but the parts list only shows the entire rear differential ($460+)

Is there a gasket that can be replaced or do I really need an entire rear diff? I was planning on spending the money elsewhere (brakes, tires).

Cost of repairs? Part numbers?

Thanks,
Oquipah

Mechanic also suggested the vent at top of differential, which can spray fluid out, especially at high speeds on the highway. I'm going to check my fluid levels this weekend to see just how much is or isn't there. On that note, how do I check the fluid?


If anyone can find the TSB on this I'd be your friend.

Thanks,
Oquipah

To check the fluid level in the rear diff you take the upper bolt out and stick your finger in. I think the fluid should be up near the bottom of the upper bolt hole. If its not then you may need to add more fluid.

Excellent, thanks! I found it in the Haynes manual late last night too. Fluid should be even with bottom of upper bolt opening.

Peace,
