16 S550 PP1 Slow Drip Differential

[DonPatr0L]

Hey All,

I have a 16 GT PP1 and I noticed and slow drip on the differential. Not enough to be extremely worried, but want to take care of it.

I can't see exactly where the leak is since the whole diff is someone coated. Was wondering what the standard cause of a leak on these cases are? Is it the axle input seals? Or is the diff cover the usual culprit? Trying to avoid dropping the diff to reseal the diff cover, but maybe I should just do both the cover and the seals?

Also, the car has about 10hrs of track time and maybe 200 AX laps

What's your thoughts on cleaning up the diff and then running it a bit and see if you can pin point the source of the leak?
Possible the diff is getting hot and the oil leak is from the vent?
How many miles are on the diff?

Only 24k

Sounds like a can of brake cleaner or some type of degreaser is in your future. Clean the diff and then see if you can better tell where the drip is coming from.

Where is the vent located? That could be the case if I over filled it too. I'll give it a good scrub and see if I can better trace it out

The breather should be located near the top on the rear cover, fill plug probably in the drivers side of the diff housing, 3/8" square hole plug. Lots of heat by the diff on the S550 chassis.

The vent exits into the RH rear wheel well. Axle or pinion seal maybe but these are fairly leak free.
