Putting car in D on jack stands (wheels off)

[MaximaGuy]

Are there any risks to transmission when the car is put in D on jack stands w/o the wheels.?

I heard a grinding sound from the passenger side axle. Not sure if it a CV that is failing or the fact that the CV is inclined when its on jack stands that there is a grinding sound. On a level surface the axles are horizontal to the floor..

Any suggestions on both my questions.?

The CV-Joints are designed to be OK in that position (unless you modified your suspencion or have a wrong CV-Joint). So you should be looking for a new CV if you are sure that the sound comes from there.
The only danger is that the car can jump off the jacks and hurt itself and it's owner/mechanic/ etc

There's no harm done if the car is evenly jacked up on all 4 corners. Just don't rev the engine too much cause that will make the engine flex on its mounts making it slightly rock back and fourth.

Just remember that with out wheels the rotors and or drums are not bolted tight to the hubs. You can flip the lug nuts around (if they don't have a blind hole) and snug about 3 of them up.
Also if you start the engine and put it into drive the drive wheels will take off on you without the brakes on. Be sure the axles are brought to a complete stop before throwing the shifter into park from drive.

I would not be going crazy with the CV shafts at full extension.

It sounds like you are starting the engine and putting it in drive.
I would not do this for prolonged periods.
The differential will probably be spinning only one side, and this is rough on the gears in it.

Thanks folks. I had to put the car in drive to check the brake job was complete before I put the wheels back and lowered it.

Thx again for your replies.

I did that on one of my cars and found out it was actually a bearing going bad.

My mechanic did that before to see where does a whine come from. He also tried using a screw driver to jam one side of the brake rotor's vent to make only the other side spin.

For short bursts, it is OK.
