Car on jackstands, engine running, tranmission in gear - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Any reason not to do this? It can be handy at times for testing, troubleshooting, etc.

I am hesitant because I am not sure about letting the rear suspension sag with power going to the wheels.

I have done this with a solid rear axle and jackstands below the axle housing (suspension loaded). Worked great. Not so sure about the camaro with IRS and the suspension unloaded.

So, what do you think?

I did it trying to isolate the source of a rear end howling noise. I don’t think you can hurt anything, unless you get your face between the tire and the fender.

It'll throw a bunch of warning lights but they'll go away as soon as you drive down the street.

not sure the CVs like those angles so be careful. Taking the rear tires off will help.

Aside from the obvious dangers of a car on jack stands in gear, as long as the RPM is fairly low, CV’s can handle a lot of angle. Angle AND RPM builds heat. The more of both, the more potential for damage - but it would take a while. They use the same ‘Rzeppa’ style CV’s as the main driveshaft in many vehicles. Albeit, lower angle, buy higher RPM.

Proceed with caution! (IMO)

I'm counting the ways it will go wrong but you could monetize it on YouTube to offset your insurance deductible.

I've done it many times with front wheel drive vehicles. With good jack stands the danger is minimal. Just build up rpm slowly, and be ready to hit the brakes if you get any bad vibration. As an added safety factor you could do it outside and not pointed at anything.
