2011 Camaro SS Differential problem? Or Axle popped out?

But in your case, you probably boogered up the splined end of the shaft that mates with the inner race of the six-ball set up. The twist tells me that. I'd expect the shaft to go before the diff...if yer lucky!

I think all of us weekend warriors worry about this. Our cars were designed much more to be performance passenger cars than race cars. Ok, a ZL1, Z/28 and to a lesser degree, the 1LE are equipped with a few track-friendly mods.

Kind of a pay me now or pay me later proposition , IMO. $80K (give or take) gets you a Z/28 track car. But something tells me they break too. Pay to play...

My question to you is, if I'm underneath the car Right? And I decided to try to pull the axle out by the diff side first. ( I know that's not the proper way to) Is it possible that the axle can pull out about 3 inches or alittle more? Also end (spline) look similar to the hub side? Cause I don't recall seeing one when it pulled out a bit without taking the other side off. Feels like I shouldn't be able to pull it like that so easily.

I have broke both over the years.

You say "Take Off Axles" like... Replacement axles? Or Axles that can withstand a launch?

By "take off" he means they are stock axles that owners have removed for one reason or another. Most often done to install stronger axles or possibly a diff/axle swap.

Thank you for the Info. I'll post back when I see these parts.

Her car was not stock. I don't remember what mods she had at that time, but I'm sure at least a cam and headers, and NOS, and drag radials.

I'm a little embarrassed to say that while I have been around axle half shafts for 30+ years, (mostly FWD) I haven't actually pulled one from a Camaro. If I understand your question, it depends on if the inner (diff side) has a MALE end that inserts into the diff or if it's more of a flange type mount. Looking at you vid and not seeing bolts, I'm presuming it's the male version. Maybe someone can confirm.

If it were a flange mount, there probably is enough "plunge" in the CV ends to allow you to remove from just the diff side. If you had to pull the longer male spline out, it could be more difficult especially with busted up parts in it.

Someone help me out here! (I know this isn't a Camaro, just showing end types

Yeah I've only.worked with fwd. I have a 04 srt4 neon before this.... So you can see why I asked lol. I don't believe it has the flange but the male end surely for a stock axle. I appreciate the pictures though. It helps me understand more

The grip is a whole lot better and the grip was slot more than I thought. I had wheel hop and that ALONE should have been red flags. But what did I know? I got a 13.03 second quarter mile, and I wanted to get my reaction time down to .1s not .4s (their lights are delayed so you'd have to launch on the last yellow light) But yes, I was dumbing the clutch and at higher rpms. So I got what I deserved. It just confuses me that for a while it worked just fine in a straight line but when I'd turn it would thump. What finally did it for going straight AND turning was a complete u-turn. Then it felt like it disconnected.

As far as your launch technique goes, you may want to look into pre-loading the driveline a little with the emergency brake. The basic idea is that you'll stage the car (or even just get to pre-stage) and then start holding the car with the e-brake as you very lightly load the clutch. You don't want to do it long - this isn't a torque converter, and it's easy to overheat.

You just want to create a light load against the drive-train, so that when you get the green you've already taken up all the slack in the drive-train - removing, or at least reducing the snapping acting of quickly releasing that clutch with a bunch of RPM in the car.

You can find good you-tube examples of this approach. It's not for everybody, but you may find it helps reduce that initial shock, and keep the car out of wheel-hop on the initial hit. Wheel hop will break stuff like crazy - that on-off-on-off application of force is incredibly brutal and tears stuff up in a hurry. If it hops, just get out of the throttle, it's not worth it.

I'll make sure to take this into consideration next time if I go thanks!

Looks good

I don't think that would be a good idea with a manual tranny like he has . You would burn up the clutch pretty quick. Although I am guessing that he has a Manual tranny from his other posts .

Sooo, is this more common than I'd like to think? Or, is it more common at the strip? And finally, is it more common on a M6?
