Rear diff leak question
I have a significant leak coming from the rear differential. After driving it, there's usually a puddle about 2-3" in diameter. My question is, how long can I get away with this leak before replacing the seal? I understand it's a costly repair but I don't want to damage the rear diff. It's a 2000 FRC btw

Check the fluid in the differential to make sure that the fluid isn't too low.
To do this, remove the plug where it is stamped on the differential "FILL". Stick your pinky in there to see if fluid is up to the bottom of the fill hole. If it isn't put some fluid in, untill it seeps out of the fill hole.
You would do the proceedure above, while the car is level.
I would continue doing this method untill the differential starts leaking a considerable amount of fluid. At that time you may want to have the seal/seals replaced.
Doing this yourself would be less than $100. for the two seals, plus the cost of new fluid.
Good luck.

Use the GM fluid that has the additive all ready in the mix.
You will have to use some type of pump to get it from the container
to the fill hole.
Pricing for the repair of the seals would vary from one place to another, with labor being the most. I would stay away from the dealership.
Check with forum members in your immediate area to see who they have used for similar repairs & who they reccomend to do the repair.
Good luck.
