Rear End Leaking after Competitive Mode Launch - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

The big variable in dumping the clutch is road surface traction. I don't care if the the ecm is limiting RPM, dump the clutch on a dead hook surface at 4 to 4.5K rpm and expect broken parts. Seen it many times at the local strip. Especially when they spray a lot of VHT and get a real tacky surface.

Take the owner's manual page that describes launch control, tear it out, and pretend you never saw it. If you prefer not tearing stuff up.

I usually launch the red car at about 5k and it has 800 foot pounds of torque coming off the line, but then again it also has a Moser 12 bolt with 33 spline axles and a full spool.

Spoke with them today about the car and they said it still looks like it is coming from the drain plug. I personally think it's an axle seal because I have seen it happen too many times. They are suppose to call GM about it to see if there is a notice or defect on the drain plugs and I'll know more tomorrow.

Just an update. After almost 2 weeks of it being in the shop they say it is the rear diff itself. New one is on order and it will be another week before it comes in. They are replacing the entire diff, insides and all.

I still think it is the drivers side axle seal though... Guess I'll know in another week.

Worst part is, all of the suspension parts, intake, exhaust and misc parts I ordered for it are all sitting in my garage with no car to put them on.

Axle seal would leak at the wheel, not at the diff. They usually leak when the breather gets plugged and can't bleed off pressure when the diff heats up causing the pressure in the diff and axle housing to blow by the seals at he ends of the tubes, then it will usually saturate your brakes. So if it's leaking below the middle of the car it's not an axle seal.

Except the camaro is IRS , not live axle. There is no axle tube , the seals are at the half-shafts on each side of the diff.

I launched at the track @ 4200, hooked up and snapped the right rear axle...not using launch control again.
