Rear diff leaking
I have a 17’ 1LE 5k miles. Noticed the rear diff was glossy looking- had a coating of fluid. Upon further examination I saw the passenger side of the diff casing was also coated with fluid and there is a ring of fluid where the axle joins. Guessing maybe a bad seal. It should still be within the 5 year power train- not sure how involved of a repair this may be.

What would be causing the fluid to cover the exterior casing? It looks like it dripped down- maybe a slow leak?

Thanks for the info. I think I saw this before but for some reason I thought I had the longer bolts.

Yeah I am the original owner. I don’t think the bolts were ever changed afterwards. Maybe they corrected them from the factory- explaining two marks?

An older thread discussing these bolts. Nothing in here discussing torquing and backing them off. Now I’m curious if the first mark was the 37.5 lbs and the 2nd was the additional 45°?? I check those bolts every time the car is on the lift and I don’t recall seeing two torque stripes. https://www.camaro6.com/forums/showthread.php?t=505246

okay if you say so, here is a pic of a correct blue paint torque mark.

Def need to investigate that TSP, your bolts have backed out. Does that have anything to do with a minor leak, I don't think so and actually in standard olden timey time rear diffs it was extremely common to have some oily staining or residue on the cover.

I’m with you on the two marks. I don’t see how a bolt backs out and ends up with a 2nd paint mark lining up perfectly with the backed out bolt.
Have you had the time to check the torque on those bolts?
