Musturd lovers, help me out...
Replacing the diff cover seal on my buddys 03 cobra today and found this...
...metal shavings/pieces and a broken tooth on one of the gears. Didn't hear any noise while driving and havn't had any driving issues. Should my buddy be worried? If he needs to go ahead and replace, what do you guys recommend?
Thanks guys.
Oh, sorry for saying musturds, this cobra would totally smoke my vette

Re: Musturd lovers, help me out...
I love mustard! Hey wait..
Those gears definitely need replacement. That's a failure waiting to happen, and if he's lucky it won't strand him out in the middle of nowhere when it does. You don't want to see what happens when one of those teeth shears and gets caught between the ring and pinion.
My question is, what caused that? Has he been doing a lot of launching? I'm assuming that he's got the stock Cobra IRS setup with the rubber bushings, and the shock loading with wheelhop is probably killing that diff.

He hasn't launched or tracked it at all. Just bought it a month or so ago. It is pullied, tuned, exhaust, maf, making 421whp 456 wtq and as far as we can tell everything in the rear is stock. My parts manager said it may not cause any issues for a long time since we got all the metal out, any truth to this, or is it foolish to not replace the gears now?

Re: Musturd lovers, help me out...
Any other opinions? Where is flimflam, I'm pretty sure the mods were done at your shop actually, not to say that has anything at all to do with it, but I know you know these cars pretty well.

It that's the power its making, your vette should put up a good fight lol. If the car doesn't get that much abuse it will be fine. I've seen a lot worse in some f150's that last a long time with no problems. If he wants to beat on it hard I would change it out, I would suggest a true track

The gears in the picture are straight cut, which means that all the power is transmitted by a single tooth at a time. So if those are damaged, then you not only lose the ability to transmit power, but the chipped/broken teeth also become a great stress concentrator that weakens the rest of the tooth a lot.
It's like breaking off a lug stud (or two) on one of your wheels. It may do OK for a while, but now the remaining studs have a higher load and the load isn't spread uniformly any more.
I'm just not sure why "I broke a diff gear tooth, do I need to replace it" is something that can actually be debated.

It's been launched hard. The case twists without a brace and causes that type of damage.
Get a BF diff brace and replace those gears
