2024 Supra possible diff leak

[FLtrackdays]

...and potentially spend thousands for a repair that would've been done, free of charge. I was willing to wait awhile to save money, but after a month, my patience has diminished quite a bit. My days of not worrying about money while working full-time are long gone.
Never would think that repair expenses would be a concern while a new $70k car is under warranty.

That does really suck man! It is a hard thing to wrap your head around for sure. I’m hoping it’s something easy for the right mechanic. Get you back on track so to speak

I got rear sway bars put on at my local shop. He had the right equipment, so took him no time at all = way cheaper than I expected. I went and talked to various mechanics about my issues at the time. Picked the right shop for me.

Good plan! I noticed over the years that using one indy shop for everything (that I choose not to do, myself) is often not wise. I used a Miata - specific shop to install all suspension upgrades for my MX5. The owner took my car to my favorite alignment shop, which happened to be across the street. And as we all know, some dealership techs are more experienced than other dealer techs.

I did pick up my Supra from the dealership, yesterday and have an appointment (Tuesday if it is not raining) at one of the three BMW indy shops I had called. Eventually, I'll get the the pucks needed to get my car up in the air to perform oil changes, etc., but for now, a person who has plenty of experience with diffs will be verifying where the leak originated.

OP: “My rear diff seems to be leaking, I’m taking it to the dealer”

Literally everyone else: “here are some things to check first to try and avoid the dealer because they are generally useless”

OP: “I chose to ignore all your advice and let the experts at the dealer figure it out, that is what they do with all their years of experience!”

Car is at the dealer for over a month…..

OP: “I took my car back because the dealer wasn’t doing anything”

Le sigh.

My priority was getting the leak documented. That was completed. Yes, it took them way too long to get the part and tools which they still haven't received.
Anyway, I found that I could back my car onto Rhino ramps (then place wheel chocks in front of the front tires) to get a better look.

Side note: The ambient temperature when the diff started leaking was near 75. Today, it was 15 degrees less.

Upon examining the diff, I found a light film of diff fluid in some areas, so I cleaned it up and went for a 40-minute ride.
Fast forward to 1-25-2024: once again backed my car on ramps and looked at and around the diff. See pics.

By the way, is this left exhaust pipe supposed to look like this?

seems strange, would bring to dealer for a lookover probably

I'd like to see the pipe-bending machine they are using. Hopefully, someone has a pic of one that looks normal. I know that I have never backed onto a concrete wall.

Yes, this is normal.

In before you ask if the ticking at idle is normal.

Too many concerts when I was young have rendered my ears desensitized. That's probably why I don't notice any ticking.

Not a Corvette exhaust...

Why/ How does this happen? No wonder why many owners replace the OEM exhaust.

It happens when the factory creates them and then installs them in Graz, Austria.

It's for clearance. Not the first car to have this and won't be the last.

You're an engineer, I'm sure you can compute how many of your rubber gaskets could still flow through those parts. RPM, rubber per minute. Corvette.

Does it look like there's a clearance problem in this photo where the curvature is distorted?
